Daily Pot Use Tied To Age of First Psychotic Episode

An anonymous reader writes "Reuters reports, 'In a study of adults who experienced psychosis for the first time, having smoked marijuana daily was linked to an earlier age of onset of the disorder.' ..."This is not a study about the association between cannabis and psychosis, but about the association between specific patterns of cannabis use ... and an earlier onset of psychotic disorders,' Dr. Marta Di Forti, who led the research at the Institute of Psychiatry at Kings College, said in an email. Among more than 400 people in South London admitted to hospitals with a diagnosed psychotic episode, the study team found the heaviest smokers of high-potency cannabis averaged about six years younger than patients who had not been smoking pot. Psychosis is a general term for a loss of reality, and is associated with several psychiatric diseases, including schizophrenia and bipolar disorder. ... "The thorny question is whether they might otherwise have developed the disease or would have not had mental illness. It's a distinction we haven't figured out yet," Compton said. ... It is still unclear whether there are safe levels of use for cannabis, she added. '"

How do you figure that? I'm pretty sure that these conditions exist in some state prior to one's first episode. There's also the fact that this particular pattern might select itself for certain demographics more than others, and the environment they are in might contain factors that do influence this.

Possibly, but that doesn't fully explain why people who smoked pot at an earlier age (under 15) were more likely to have psychotic episodes at an earlier age, nor why those who smoked stronger pot in larger quantities were also more likely to experience such episodes. The study found both effects. And since the study focused on people who had psychotic episodes in the first place (i.e. people who likely had mental issues to start with), it's unlikely self-medication is the explanation. Possible, of course, but unlikely.

Obviously, we'd need a study that has people smoke pot with a control group that doesn't smoke pot to be sure, but that might never happen due to legal and ethical concerns.

I used to smoke pot a lot in my mid teens (in the 80's). One time I had a very scary panic attack while in school after smoking some at the bus stop. I didn't know it was a panic attack at the time because I never had one and did not know what the hell was going on. I was able to play it off as I was just sick but it scared the shit out of me and they sent me home. Where I lived people were more accepting of pot use so the school nurse probably suspected drugs but just let it ride. My mom knew I smoked pot and I talked to her about it and she explained what she thought had happened. None of the others that smoked that same pot that morning had any problems so I know it was not spiked with something else. I smoked pot for about the six months but I did not like to if there was a chance I'd be by myself since I associated the panic attack with the pot. I made my friends were going to be staying around or we were doing something in a group. About 6 months later I eventually just quit doing it and haven't touched it or anything except alcohol since. I don't think it was the pot that caused my "problem", probably just made a problem I had worse. At the time, my dad had just died from cancer, it was close to Christmas, I had basically stopped going to school, my mom was in total shambles from my dads death, my paretns business was about to fold without my dad being around, there was a lot going on I was probably under a lot of stress. I went almost 25 years until I had my next panic attack. Turns out my mom and sister both have them. My mom worse. A lot of people have various levels of panic attacks, I did not know that until I started poking around and lightly touching on the subject with some friends and trusted co-workers.

Re: Cause and effect may be backwards

Let's be fair here. In the 1920s up through the 1950s/1960s, it was fairly common for a man to have a bitchy wife be committed to a mental hospital, and in the 1940s/1950s they were even labotomized for "anxiety and agitation".

There may have, in fact, been lower rates of psychosis in the 1920s onwards until the 1960s/1970s, but given the diagnoses at the time, it'd hard to ever be sure or be able to draw a direct comparison.

Re:Cause and effect may be backwards

Not necessarily. It could be that marijuana increase schizophrenia, and some other factor decreases schizophrenia fore than marijuana increases it. I'm not saying this is the case, but you can't just look at a period where schizophrenia decreased and say that everything that increased in that time period can't be increasing schizophrenia.

Re:Cause and effect may be backwards

[Luckyo]

Finns use alcohol heavily, but marijuana usage in the country is fairly low and stable afaik. If anything, that would suggest that alcohol isn't inducing schizophrenia. Which is pretty unlikely to be true.

Study itself makes it clear that they assume that certain factors causing the mental illness have declined. Perhaps it's the brutality of life, and not needing to worry about tomorrow? We do have quite a bit better social security network around here than before WW2 for example.

Re:Cause and effect may be backwards

[Curtman]

If the incidence of schizophrenia decreases during the same period as marijuana usage increases, it becomes very difficult to show a causal link. That's the situation this discussion leads to. Incidence of schizophrenia should follow the increase in marijuana use when plotted against time, it doesnt. It's inverse.

Re:Cause and effect may be backwards

Yes. Unsurprising.

I suspect there is another, much more insidious link, and it's along the lines of the withdrawal (period of increased likelihood of suicide) associated with the cold turkey withdrawal from multiple other prescription mood amplifiers.

Perhaps they became paranoid because "the man" was really out to get them.

Lets get our terms defined here. A paranoid psychotic episode is only one possible aspect of a psychosis. Perhaps the individual might experience fits of uncontrolled laughter and even the munchies, these episodes can been seen in many people who show signs of psychosis. Or individuals who smoke pot for that matter. Reality distortion during a psychotic episode is a difficult thing to quantify and can vary in degree to such an extent that qualifying every episode that requires intervention to be a psychotic one is a fools gambit.

However would you like to have someone who smokes high potency pot on a regular basis for an airline pilot? From my experience most who are heavy pot users are better suited for janitorial work or a space academy. Or a even a regular spot on reality tv shows. I personally even temporarily considered surrendering our planet to these guys while waiting for your order at KFC like I once did when considering whether or not to ask the clerk if they were having trouble plucking the chickens because the order was taking too long and I HAD THE MUNCHIES! Either way to conclude that psychosis is always manifested in paranoid delusions on the contrary, delusions are an integral part of our psychological make up as a species and can even be productive if seen in a more gentle context.

Re:Cause and effect may be backwards

If group A's symptoms start earlier than group B and both self-medicate, group A will self-medicate first.

Re:Cause and effect may be backwards

[strstr]

It exists in a very small amount. Drugs are the actual cause of psychotic disorders in many. If you look at the state you're in on the drug, you're shit wasted, experiencing all the effects of psychotic disorder, including hallucinations, paranoia, and sensory and cognition issues. The longer a person uses, we know they develop a lot of paranoia that seems to last long after the drugs last use. Meth users also go completely shit crazy, and long-term use nearly always results in severe brain injury.

Lastly, if you go into a hospital or see your doctor on pot or meth, even if they know you used. They're likely to give you a diagnosis of schizophenia or bipolar, and start major tranquilizer/antipsychotic treatment immediately.

I don't agree that you have schizo or bipolar if this happens, but you are usually pretty fucked up and you might have those symptoms for months or years even after your last drug use. It's my personal knowledge that the doctors should be pushing neuro rehab and detox on these cases, but aren't, so people never truly stabilize and the easiest thing seems to be to diagnose a mental condition instead, which is most cost effective but the least effective option out there. They use pharma to treat at that point, then onset of brain shrinkage and brain injury from pharma makes it permanent.

If anyone looks at the state hospital facilities and institutions, you're likely to trace most peoples mental symptoms back to a time they used drugs or alcohol. And at that point, we sell these people explanations that include the misconceptions that "they were self medicating" and shit, but usually the drugs were the sole cause of the persons demise. I have not seen many people who actually did self medication with street drugs. Someone made that up to sell mental health services, to make it look more legitimate for insurance qualifcation, court procedures, and even the media and legislatures so they'd approve funding and laws that supported their particular area of business.

Re:Cause and effect may be backwards

[denzacar]

Obviously, we'd need a study that has people smoke pot with a control group that doesn't smoke pot to be sure, but that might never happen due to legal and ethical concerns.

That's easy.
Just check the records of all psychotics who haven't smoked pot prior to their first episode - then compare their ages.

Actually, that's EXACTLY what the did in this study.

The earliest onset was seen among those who used high-potency cannabis daily - on average their first psychosis was 6 years earlier than for non-users.

And since the study focused on people who had psychotic episodes in the first place (i.e. people who likely had mental issues to start with), it's unlikely self-medication is the explanation. Possible, of course, but unlikely.

Why would it be unlikely?
Under the assumption that the psychotic episode has an underlying cause other than just smoking pot, they could have been treating that underlying cause by self-medicating with pot.

As for the study we'd need (har-har), it would have to include many thousands of children who would be separated into several groups. The study would last for several decades during which time participants would be tested for drug use daily.
Groups would be given either a single potent dose, several less potent ones, a single less potent dose but the participant would be told that it IS a very potent one, several groups would get several levels of both single and several doses, one group would be carefully kept clean of any pot use by having them handcuffed to a police officer (one per participant) and one group would get a full blown placebo.

Then, we sit back and wait until they all die while we gather the psychotic episode incidence among all the groups.

Study could be funded through well informed investments into snack and bong industries.
As for the legal and ethical concerns, one way to get around that is to convince military that it is actually a study to create super-soldier serum.

Is schizophrenia on the decline in Canada?
The preliminary comparison showed a 42% decrease in the number of first-admission schizophrenia cases over 20 years. In the main study, the annual inpatient prevalence rates decreased significantly (52%) from 1986 to 1996 with no corresponding change in outpatient rates, regardless of sex. Although total major affective disorders increased, this was due to an increase in major depression, not bipolar disorder.
This is the first Canadian case-register study to support the widely reported falling rates of schizophrenia in other parts of the world over the last 40 years. Since this is a geographically limited prevalence study based on only 10 years of data, further research over longer periods of time in other regions of the country is required to support or refute these findings.

Canadian teens lead developed world in cannabis use: Unicef report
This is the second time in a row that the WHO study has ranked Canadian teenagers as the highest cannabis users, though the percentage of teens itself has dropped. In 2002, the same survey showed that 37.5 per cent of 15-year-olds in Canada had used cannabis in the past year.

Dude, we're talking about POT, not heroin or cocaine or alcohol or tobacco. Pot is not addictive. One can of course be habituated; if I'm used to having a glass of orange juice every morning for five years and then there's none, I'm going to miss it. If I'm clinically depressed it may drive me to suicide, but that doesn't reflect on the orange juice, it reflects on a mental illness.

I've been smoking pot for over 40 years. Sometimes none is available and sometimes I can't afford it. Yeah, I miss it when I can't afford it or there isn't any available, but if I can have my coffee or pot but not both, I need my coffee.

This has nothing to do with addiction. It has to do with other mental illnesses.

I've personally never gotten high smoking a spliff. And I now understand that smoking any plant creates a risk of lung cancer. I have enjoyed the pot high from both vaporizers and space cakes/cookies though, but imho consuming in this fashion rapidly takes the high from "just enough" to "too much".

I'd honestly rather do a small sub-hallucinogic dose of a proper hallucinogen like mushrooms. Pot relaxes you and mushrooms don't really, but you feel more "on" and clear headed with mushrooms.

Any psychoactive substance has the potential for addiction, just because pot is less likely to have severe withdrawal symptoms than some other substance, does not mean that it's not addictive.

Similarly, the probability that there are other factors that decrease incidences of schizophrenia in such a way that it almost nullifies the effects of marijuana is extremely slim.

My point is that we know that alcohol does in fact cause severe mental problems.

As a result, the similarity points at the conclusion that it's something else entirely that's affecting the issue, such as for example better diagnosis. Like not seeing things like homosexuality, weird behavior, or just being different as a mental illness that needs to be treated. This was a common issue in early 20th century and that is the comparison point.

Re:Cause and effect may be backwards

Heavy pot smokers that start in teens hit the magic number of "fuck, my alveoli are enlarged and can't function as oxygen exchange all that well any more" (emphysema) around the age of 30 though. Smokers that start around the same time usually hit that about ten years later or so. It's one of those things they don't really advertise because it doesn't sound as scary as "oh god that awful looking cancerous lung" but pretty much any doctor that works with human lungs will tell you that onset of emphysema happens much earlier and is a severely limiting factor to human life.

Cancer comes much later, but not being able to take more than a few running steps before you start running out of oxygen even though you're pushing 60 breaths a second is quite a nasty problem to have for decades before cancer comes to finish you off.

Then there's the whole issue of drug use and addiction being concentrated to the same people, so most addicts are to an extent mixed users.

I've seen it with people and they do not recover from it, unless they quit and give themselves a reset [reset not rest] then they can go back to smoking. Its a balance, of smoking and just enjoying it, and smoking and burning out your mind over issues you didn't deal with while sober.

And then this more then likely is another bullshit study over pot. I've got to wonder if the US isn't involved in some form or another, as they've always been, when it comes to studies done in the US. Now I question [again just one of those 'what if' thoughts] if the US are using other countries to do these ridiculous studies.

I do. I'm only suggesting that if marijuana use increases 1000% and there is no epidemic of schizophrenia afterward, there doesn't seem to be any reason to assume a causal link, or to fear one..

There may be underlying factors influencing the decrease in schizophrenia, but there is absolutely no evidence that using cannabis will increase your likelihood of being diagnosed with it.

Actually odds are there is, but only if you admit to the cannabis use to the diagnoser, because then they'll be predisposed to diagnosing you with it

This conversation is about marijuana. Your refences to alcohol, meth and 'drugs' in general suggest that you make no distinction between these substances and marijuana.

Ignoring this and lumping them all together suggests to me that you are serving an agenda rather than attempting to actually add information to the discussion.

Re:Cause and effect may be backwards

First of all, you didn't even read the fucking summary.
"This is not a study about the association between cannabis and psychosis, but about the association between specific patterns of cannabis use ... and an earlier onset of psychotic disorders."

Secondly, there's no way you actually have a statistic that proves there's no increase in psychosis since the 1920s. I'm fairly certain we we're much more aware of mental health now than we were then. Thirdly, even I'm wrong and you have a source, it would mean nothing as other factors could have coincidentally had the opposite affect on the rate of psychosis. And again, even if you somehow had a way around that, it still wouldn't matter because this isn't even what the article's about in the first place

I need my coffee.

That's because caffeine does have withdrawal symptoms. I went overboard a while back on coffee: you get insensitised and need more for the same effect. Eventually, when I needed some very fine motor control skills, I realised I had to go cold turkey for a bit.

Oh god that was a miserable fortnight and included headaches, sleeping trouble, bad indigestion and a real jonesing for coffee.

Anyway, it passed and now I drink coffee in much more sensible quantities.

As for addicted: coffee (caffeine) is mildly addictive. It is possible to quit, but I like coffee a lot. Provided I'm sensible, why would I want to stop?

This is the thing that annoys me about some people talking about (say) pot. "If it's not addicitive, then quit." Why would one want to quit to prove a point to some random nay-sayer who won't be convinced anyway? One could say much the same about fried potato. No way I'm going to stop eating that because it's so darn delicious (and the hefty dose of fat and carbs does have an effect on my mood). Of course I could stop eating it, but no, I'm not going to.

I'm not a pot smoker/eater myself, but these arguments really annoy me. For some reason people seem to think they're OK because it's a "drug".

I'm also not going to stop drinking fine scoth either to prove I'm not addicted to booze.

Re:Cause and effect may be backwards

Heavy pot smokers that start in teens hit the magic number of "fuck, my alveoli are enlarged and can't function as oxygen exchange all that well any more" (emphysema) around the age of 30 though. Smokers that start around the same time usually hit that about ten years later or so. It's one of those things they don't really advertise because it doesn't sound as scary as "oh god that awful looking cancerous lung" but pretty much any doctor that works with human lungs will tell you that onset of emphysema happens much earlier and is a severely limiting factor to human life.

Are we talking about the active substances involved or the method of delivery here? Both nicotine and THC are consumed in a variety of different formats and ways, and I'd be willing to bet that the phenomenon you are talking about is not particularly prevalent in THC consumers who get it via digestion, for example. Even in smokers of cannabis, there is considerable region variation in preferred methods and formats - leaf/buds, oil, hash, etc., many places around the world mix cannabis products with tobacco and smoke a joint like a normal cigarette, pipes, bongs, vaporisers, etc.

The "researcher" makes a living conflating correlation and causation. AKT1 gene my arse. Marta is full of shit. Most psychotics have their first attacks in the late teens - but "proof" "Skunk cannabis" causes psychosis is that smoking it "for many years" (you read the study right?).

If you spend most of your time stoned on strong Indica you are psychotic. The rest of us smoke because we enjoy it as part of our lives. If you indulge regularly in something that leaves you couch-locked it's not the drug that's the problem - it's the motivation. Those people smoke "to get out of it" - their poly-drug users (classic "self-medicators"). But hey, it's not my fault I'm a fat fucker either, I inherited the heavy bone genes, it was a childhood diet, poor self-esteem, distorted body image, blah blah - and any "scientist/dietician/psychologist/neuroscientist" that supports that view isn't doing in a cynical attempt to further their own career so lets just all have a big hug OK?

I'll stick with the facts - a large percentage of people my age have been smoking for 40+ years, we're just not the people you would pick as "smokers". Nor are our children or grandchildren.

Or, people who consume excessive amounts of any drug have what we now classify as "mental illness"; e..g. psychosis, neurosis, personality disorder, etc. It doesn't take many hours reading history books - or even watching PBS/Cable/Satellite TV to discover that people have been seeking out these substances, and consuming them, for a very long time. Some people can tolerate them, others cannot, and others take them to excess (and their ultimate detriment). Given that evolution has not eradicated this desire from humans after a few million years, perhaps, just perhaps, we are wasting our time trying to "fix" humanity here, and the trillions of dollars spent trying to eradicate drug use would be better spent understanding how to prevent it, and treat it, and keep the abusers from committing crimes that destroy innocent people.

In other words, some people are going to get high too often no matter what you try and to about it.

Our insistence on eradicating this behavior by throwing insane amounts of money at eradication, which isn't working, is foolish. When the fix doesn't work, you do something else, not apply the fix more vigorously. Doing something over and over with the same result is, in fact, is form if neurosis.

Exactly. And it is well known that marijuana causes an increase in active disease in people predisposed to schizophrenia. These are people who are likely to drift in and out of a disease state if unmedicated anyways. The studies already have shown that it does not cause schizophrenia in people not already at risk.

This study is about a different thing, psychotic episodes. And it is the same type of result; it shouldn't be assumed to imply a causal link in people not already predisposed to have psychotic episodes. It is potentially a bigger deal than schizophrenia, because in that case people can quit using and the effect usually goes away within 2 years. With psychotic episodes, it is unknown if this reversal will happen.

Not necessarily. It could be that marijuana increase schizophrenia, and some other factor decreases schizophrenia fore than marijuana increases it.

Re:Cause and effect may be backwards

The damage caused by cannabis alone is definitely nowhere near as unmistakable as tobacco. Pretty much everybody who knows tobacco addicts can see for themselves that their lung function fails over the years, but getting evidence of such an effect for marijuana is pretty iffy, even with sophisticated statistical analysis of good studies.
"COPD risk among people who smoked marijuana, but not tobacco, was slightly higher than among nonsmokers, but the increase was not statistically significant." Tan, W.C. Canadian Medical Association Journal, April 14, 2009.
(they found a somewhat greater increase in risk for smokers of both tobacco and marijuana than just tobacco alone; that's not too surprising, tobacco is synergistic for the bad effects of other substances, as it interferes with the lungs' ability to clear themselves of foreign substances)
"Given the consistently reported absence of an association between use of marijuana and abnormal [lung function] or signs of macroscopic emphysema, we can be close to concluding that smoking marijuana by itself does not lead to COPD" Tashkin, D. New England Journal of Medicine, 1976; vol 294; similarly http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2665954/
"Currently, the evidence that smoking cannabis causes emphysema and bullae is limited to these case reports and therefore remains anecdotal. Although Tashkin et al. demonstrated modest short-term decreases in gas transfer (DLco) among 30 men allowed to smoke cannabis ad libitum for 94 days,[15] none of the population-based studies have been able to confirm that cannabis consumption is associated with persistent impairment of DLco.[11,15,16] This is in stark contrast to tobacco smoking, for which a reduction in DLco is probably the most sensitive indicator of parenchymal lung damage. In Aldington’s cross-sectional study, exclusive smokers of cannabis were much less likely to show evidence of emphysema on high-resolution CT scans than tobacco smokers, suggesting that macroscopic emphysema is not a common consequence of cannabis use.[11]" http://www.medscape.org/viewarticle/747982_4
"Smokers’ lung function was worse, unsurprisingly (pack-a-day tobacco smokers had FEV1s 63 mL lower; 20-pack-year smokers’ FEV1 were 101 mL lower). But in marijuana smokers who had smoked up to 3,650 marijuana cigarettes (10 “joint-years”), FEV1 and FVC were higher than matched nonsmokers. At these common levels of marijuana use, there was a steady dose-response relationship: the more marijuana smoked, the better the lung function (FEV1 increase of 13 mL/joint-year). Even in the heavier marijuana users, FVC remained significantly elevated by 76 mL over nonsmokers. Only those smoking large amounts of marijuana every day began to display decreases in lung function. All these trends were highly statistically significant (p 0.001), and supported by the large sample size and body of spirometric data." Pletcher MJ et al. Association Between Marijuana Exposure and Pulmonary Function Over 20 Years. JAMA 2012;307:173-181.

Marijuana is a plant, grown to supply fibres for clothing, ropes etc. and, the seeds with a high protein content for human consumption. Now if you are talking the various other substances to two most well known being THC and CBD, both of those have completely different affects and the ratio between the two have major differences in intoxication and pain relief.

Basically the bullshit propaganda is pretty obvious as it just lumps marijuana together because it affects pharmaceutical corp profits, alcohol profits, wood pulp profits, synthnic fabric profits and keeping it illegal feeds the insane ego of psychopaths and narcissists who want to destroy peoples lives and target marijuana users gives them plenty of people to crush, lord it over and destroy (those people are truly sick fuckers) and it has nothing at all to do with the intoxicating affects.

Re:Cause and effect may be backwards

[Luckyo]

Let me simplify. There are far fewer studies on cannabis than tobacco for one simple reason: number of users and illegality of usage. That makes conducting reliable studies on people with similar level of impact pretty much impossible.

So it remains "anecdotal". Which in this case means "doctors actually working with patients keep consistently seeing the effect but clinical studies find it hard to pinpoint due to low pool of potential candidates for testing".

It can also trigger a panic attack if you get too high don't know what's happening or going to happen because you are a new user. Pot can also affect the imagination which could lead to paranoia.

News at 9, if you drink whisky every waking hour you'll develop mental "problems" - oh wait, you have mental problems if you drink whisky every waking hour.

A lot of people smoke. A lot of people smoke a lot. (and it didn't start in the 60s, just became mainstream, I'm a grandfather and my grandfather "goofed off" in the Merchant Navy "as a lad". Cannabis in Scotland predates the Romans.)
So it's a subject I'd like to see researchers take seriously - but the the current regime of "funding is only available for research into the dangers" and the piss poor science doesn't do that. In the UK where that crap researcher did that "polling" you've got a few major factors that stop me from taking the "paper" seriously. Absolutely no effort is made to seperate the effects of contaminants - deliberate or otherwise from the effects of cannabis. I've seen some alarming studies of the contaminants in street weed in the UK - radioactive lead and polunium in the Nigerian imports and hydro fed with fertilizers made from metal refining by-products, even silica being added to Dutch imports, and the majority of local grow-op bud is heavily contaminated by cut flower preservatives used to try and increase profit by making the buds weigh more (Budswell, glycrerine, etc). Then you've got environmental pollution resulting from poor ventilation in overlit grow-rooms - as well as nasty levels of nitrates from overfertilization (nitrides when smoked).
I've also seen some interesting results from a study in Australia where classes of students were interviewed by men and women - even when the surveys are properly structured (which they often aren't) people lie. In the UK, the US, and Australia hospitals and GPs gather data that is deliberately misused to support particular anti-pot agendas*1. If you wind up in an Emergency room or a psych ward your answers to drug use questions will be misinterpreted to further those agendas. No surprise that we suddenly have an enormous number of people "wanting help to quit cannabis" when the police are no longer allowed to issue a simple fine (no criminal offence) for cases of small possession and cultivation. The Drug Council suddenly find proof for further funding citing an "increase in arrests" followed by courts in (for example) Australia offering mitigation or suspended sentences if the person being charged "seeks treatment".

I'm also not going to stop drinking fine scoth either to prove I'm not addicted to booze.

People have a bad habit of taking statements literally whenever it will let them trivialize and ignore what other people say. To the layman there is no difference between drug addiction and drug dependence. They lump both in as addiction. What I see, as an outside observer is the laymen using addiction as an argument to which pot advocates tend to respond with the true statements that pot is not an addictive drug. Since the laymen tend to be ignorant of the difference between drug addiction and drug dependence it just spirals down from there because the laymen aren't able to articulate that it's the dependence that they are concerned with. I find that when drug dependence is used, instead of addiction, pot advocates tend to not fair as well because all their normal talking points tend to be structured against the fact that pot is not addictive. So the advocates don't address the points that the detractors are concerned with.

For what its worth, it does appear to me that many pot users do have a psychological dependence on marijuana use. They, perhaps unconsciously, use language that suggests dependence (need vs like) or describe scenarios of repetitive use or situations where they feel uneasiness or other issues when separated from the drug.

There is a difference between saying "I have proven that lion roars don't cause earthquakes statistically" and "I am assuming lion roars don't cause earthquakes because this seems too unlikely to even warrant effort to verify"

I think it is reasonable not to do any research into whether lion roars cause earthquakes.

Are you really suggesting that you think it is reasonable to say that every chemical in marijuana has zero effect on schizophrenia, and that we are so confident we don't even need to check?

I am not saying that we need to act as if marijuana does cause schizophrenia until it is proven that it doesn't (e.g. recommending schizophrenics not use marijuana, etc). I am just saying that we need to acknowledge that from a scientific point of view we don't know the answer to this question until we do the work.

The difference between lion roars and earth quakes is that no one can even give a plausible reason to of how this might be true (as far as I know). Even if someone "proved" a causal link between lion roars and earthquakes, the focus would immediately be on what this person did wrong to arrive at such a ridiculous conclusion.

If someone actually did prove a causal link between marijuana and schizophrenia, I don't think anyone would say "How can that be, it is impossible for these things to be related". So I don't think this is a good comparison.

this is complete bullshit, i know from personal experience that if you are in a hospital, under observation because of the effects of drugs they will wait until your system is cleared of the drugs to make a definitive diagnosis, they know all too well the effects of all of the major drugs and how they can mimic actual psychological conditions... they are there to help you not hurt you.

in the case i know first hand, the treatment of tranquilizers and/or anti psychotic drugs was completely voluntary and unless there is a court order for these treatments prior to hospitalization it is illegal to force a patient on this medication or any medication other than that which might save their life (e.g. naloxone for heroin overdose).

Re:Cause and effect may be backwards

[strstr]

see, in theory that would be correct. but in practice, it is not.

I point you in the direction of my friends case. young guy, completely healthy at age 18. smokes a ton of pot, .. decides to try meth out of pure pressure. the dude went hay wire, psychotic as fuck, took his underage girlfriend on a speeding spree, then got arrested for all the crimes he'd just committed, WHICH included kidnapping his underage girlfriend, outrunning a few cops, wreckless driving and endangerment, etc.

No one got hurt and his girlfriend had the time of her life, but cause she was 17 the judge said her mom could press charges on her behalf.

Anyway, dude was taken to jail high off meth - although he was functional and coherent. he was apparently hallucinating off his ass in jail, and the guards took it upon themselves to beat him up and tase him. They did not try to do any type of detox or hospital care for the meth, ... the taser caused him to have a heart attack and caused brain damage from the severe convulsion he had after it struck, which basically could have been IMO an issue with the meth in his nervous system. At the hospital, they did not diagnose "meth use," and he was shipped off to a state mental institution for evaluation, where they diagnosed him with bipolar. they forced a ton of drugs on him, misdiagnosed, and sent him back to court to use the insanity plea, resulting in forced commitment to the mental health system where he's now stuck living out his 5+ year sentence for a crime he pleaded guilty to but was not guilty of.

Out of all the guys I know at the local state hospital, nearly half are there due to some drug condition. At least all my friends I met in there got there on drug induced psychotic episodes, and they were not observed and let go once the drugs wore off.

I do not know of many hospitals that will not see your psychotic episodes on drugs as schizophrenia, bipolar disorder, or psychotic disorder not otherwise specified. because the drugs cause all the effects of psychosis and bipolar, including rage, manic episodes, anger outbursts, hallucinations, paranoia, etc. And people seriously get treated like they're really mentally ill. Come into the ER on heroine in Eugene, raging out, and they'll give you antipsychotics (Geodone/Haldol). And you might leave diagnosed with psychosis and other conditions.

also, they can force any drug they want usually, based on the doctors opinion that it was an "emergency" and impractical to obtain informed consent. they do it all the time in Oregon. you get practically no say in the matter. they will usually start an involuntary medication process the day of admittance, and I have seen to many doctors not wait for the process to be done before forcing medications.

Nope, this is what I'm saying, quoth:

But in science we don't protect a hypothesis, when it is contraindicated by the evidence, by inventing unknown unrecorded unexplained confounding factors.

If you study two things, and there is no measurable correlation between them, then it is only reasonable to conclude that there is no link between them. Although it is technically slimly possible that the two things are linked, but some confounding factor precisely counteracts the link such that the measured correlation is zero, that cannot be reasonably proposed without some evidence. Speculation isn't good enough, which is what you did when you said this:

It could be that marijuana increase schizophrenia, and some other factor decreases schizophrenia fore than marijuana increases it.

That's all I'm saying. Anyway I don't feel combative about this issue so I don't want to harp on it. It's a minor point.

Re:Cause and effect may be backwards

[CauseBy]

Fair enough. I am an asshole. I'm not wrong though. The null hypothesis is the assumption that two phenomena are unrelated and what I said is that the null hypothesis doesn't need special protection. That is right.

Re:Cause and effect may be backwards

[TsuruchiBrian]

But in science we don't protect a hypothesis, when it is contraindicated by the evidence, by inventing unknown unrecorded unexplained confounding factors.

You don't need to invent them. But you can and should assume that there are some, and take appropriate steps to mitigate the effect of possible confounding factors you may be unaware of.

If you study two things, and there is no measurable correlation between them, then it is only reasonable to conclude that there is no link between them. Although it is technically slimly possible that the two things are linked, but some confounding factor precisely counteracts the link such that the measured correlation is zero, that cannot be reasonably proposed without some evidence.

If you have already taken appropriate steps to eliminate confounding factors, and there is no measurable correlation then it is reasonable to conclude that there is no link. If you haven;t taken the appropriate steps to eliminate confounding factors, then it doesn't really matter what you measured because it's not really useful.

Speculation isn't good enough, which is what you did when you said this:

It could be that marijuana increase schizophrenia, and some other factor decreases schizophrenia fore than marijuana increases it.

I also said I wasn't suggesting this was true or even likely to be true. I was saying that it is important to take steps to eliminate confounding factors because things like this can and do happen. This is why we have statistical methods to mitigate confounding factors

Concluding that there is no link between schizophrenia and marijuana from the fact that schizophrenia went down during a time when marijuana usage went up, is not scientifically or statistically rigorous. You need more data to make such a conclusion. For example a double blind study with a simple random sampling, etc.

Re:Cause and effect may be backwards

[TsuruchiBrian]

When you do an experiment, if your hypothesis is proven true then the null hypothesis is disproven. If you don't actually do an experiment, then you haven't done anything to prove the null hypothesis.

I don't know what you consider "special protection", but I am claiming that you need to actually do an experiment to conclude a null hypothesis in a scientifically rigorous way.

When we assume that lion roars don't cause earthquakes because it's a stupid hypothesis. We haven't actually proven the null hypothesis, we are just assuming on intuition and not on evidence.

If we actually did an experiment and can not show a link between lion roars and earthquakes, then you can conclude the null hypothesis by default. But you have to at least try before arriving at this conclusion.

Self medication

[starworks5]

Many people who have psychotic episodes, feel the need to prevent those psychotic episodes, and will be "self medicating" themselves. Its similar to saying that people who take lithium salts are more likely to develop psychosis, while there may certainly be a causation there is no correlation. This is why we have twin studies after all.

But, is it the THC, or the lack of social support and constant surreptitious activity required to obtain and use pot that leads to earlier onset?

Re:This just in...

[Will.Woodhull]

Parent post as well as several others are missing an obvious key piece of information:

This is not about typical pot smokers. This is about persons who get stoned every day (and some are probably somewhat stoned every waking minute).

Being stoned most all the time is of itself aberrant behavior, so its association with other aberrant behaviors that cause a diagnosis of psychosis should not be a surprise. A useful conjecture is that there may be a single underlying cause that can lead to chronic marijuana abuse or psychotic behavior, but thinking in terms of one progressing somehow to the other is not so useful.

At a guess, the typical use of marijuana is probably more like once a week, or two or three times a month. Has anyone seen any studies of how frequently pot smokers get stoned?

Re:This just in...

Re:This just in...

I've seen no studies, but I know a lot of pot smokers and it's all over the board. Some smoke rarely, some grab the bong before they're out of bed. I'd say there are a lot of daily smokers, though, most working-class (construction, factory) folks I know are sober all day, come home, eat dinner, then smoke a few hitters and drink a few beers while watching the tube.

I'm not sure the OP is wrong, or that this shows the pot is harmful.

As you said the pot isn't causing the schizophrenia because the schizophrenia is there already, it's just correlated with an earlier onset of psychosis. So this is consistent with people who have a more severe form of the disorder self-medicating to cope, it's also consistent with people having other emotional issues that make them more prone to both pot use and psychosis.

The 6 years is a big number so assuming their numbers are good a causal effect definitely can't be dismissed, but it's not the only answer.

However, if the schizophrenia starts in childhood, that means it predates the use of pot, which lends credence to the theory that mental illness leads to pot.

Look carefully and you will se that this is circular reasoning. Try this rephrasing: "what's happening here is that those who succumb earlier were smoking pot". That reverses the causality.

Read TFA again. It doesn't say that people have signs of schizophrenia in early childhood because they smoke pot (in early childhood??). It does say that one interpretation for the link they found is that schizophrenics tend to self-medicate.

..there probably isn't a "safe use level".

however, and here is the big thing, the thing to test against should be daily alcohol use of comparable amount - or if possible, test against whichever it is the people choose if they have both options available.

though, I'd reckon that if you're likely to have psychosis of some sort you're already more likely to be choosing to be a fucking _daily_ pot smoker for 20 years - if you get little crazy from being high 20 years that's not even news - but that is not the point, you go pretty fucked just from drinking 8 beers a day for 20 years too...

Re:in the context of society..

[Anonymous Coward]

Though I agree with your approach here, doesn't this just suggest that cannabis should be regulated as least as heavily as beer, even if it is legalised?

Such as, being arrested for being high while driving? Not selling to under a certain age? Being treated as an "addict" if you have more than X amount of consumption (alcohol isn't "addictive" in the same way as cannabis, I assume from a background of absolutely zero knowledge)? It being frowned upon to be high in public?

And, additionally, as it's comparable to smoking tobacco (though statistically less damaging directly), should it not be being illegal to smoke it in public places, enclosed spaces etc.?

The problem I have is that it probably IS less damaging that some of the things we have considered "acceptable" today. But that doesn't mean it should be unregulated even if legalised either. And I'm sure people would moan like hell if you legalised it but had to buy cannabis in specialist stores, children couldn't be exposed to the packaging or fumes, you could be arrested for being high (not even GETTING high, but just being high) in public etc.

I'm not sure that the legalisation in such an environment is actually worth the effort, given the regulation that it would have to undergo to match equivalent (or "better") such substances. Especially when, in general, we are going the other way as a society - in my country the alcohol laws are a lot stricter than they were when I was a kid.

My theoretical solution for a lot of things is "legalise it, tax it, regulate it" - a solution that cuts out a lot of the problems of illicit SUPPLY (which is the main problem with such things), not illicit, personal substance abuse. But I'm just not sure that approach is worth the gain for something like cannabis.

Alcohol is significantly more addictive than cannabis. This relatively well-known chart is a good starting point (despite being ugly and imprecise; it covers the general idea).

But I'm just not sure that approach is worth the gain for something like cannabis.

While I have no personal interest in cannabis (I don't like any drug that messes with my ability to think clearly - cannabis and alcohol both included), I do think this approach is exactly what is needed for a variety of drugs, cannabis included. Take a look at how many people are currently in prison for cannabis related offences around the world (and especially in the US) and think about what it's costing to keep them there. This - in and of itself - is enough of a reason that it'd be worth it.

That's not really the point. The question isn't whether X is less harmful than Y, the question is whether X is harmless enough to be legal. The fact that there's a large number of individuals that are more concerned with their own selfish interests, does not make for a compelling argument for legalization. If we legalize pot on that basis without bothering to go through the usual process of the legislature, what else will we legalize in that fashion?

The fact is that pot smokers have been a minority for quite some time, if they weren't a minority, then it wouldn't have been an issue to get politicians elected that favored ending prohibition.

In the end, maybe pot is safe, maybe it isn't, but we're apparently going to legalize it before we know the answer because a large number of selfish pricks don't feel like going through the proper legal route to changing the status.

Re:in the context of society..

[YttriumOxide]

That's not really the point. The question isn't whether X is less harmful than Y, the question is whether X is harmless enough to be legal.

Firstly, if Y is considered harmless enough to be legal and X is less harmful than Y, then surely the question of whether X is harmless enough to be legal is already answered, isn't it?

Secondly, asking the question this way ignores the harm of X being illegal. The war on drugs is a very harmful thing to society - far more so than the drugs themselves.

I fully believe that if all recreational drugs were legalised, there would be new problems in society that we hadn't dealt with before, but the overall amount of harm would be lower.

Impaired implies a lower level of execution. The evidence suggests that marijuana does not lower the level of driving execution, therefore marijuana is not a driving impairment under laws which generically describe driving while impaired.

Speaking of side effects of the War on Drugs, there was an interesting story the other night on the news in Denver.

A lot of pot shops are employing military grade security personnel to protect them these days. Granted, one of the most likely reasons is that this is a cash based business (the only non-cash transactions are based on creative use of ATMs), so there is motivation from others to rip them off on their way to deposit their monies. However, it is clear that the need for such specially trained security is due to the fact that pot was illegal for so long and run by the black market. Now you have those same thugs trying to rip off these businesses trying to get their hands on the product so they can take it back to the black market.

Had there not been a War on Drugs in the first place, there really wouldn't be this need for such high security at these shops.

Of course, on the other hand, it has helped to improve our local economy. I would say that I have approximately 20 friends that I see on a regular basis. Out of those 20, nearly half of them are employed directly by pot facilities, and several more are employed indirectly by businesses that have pot shops as clients.

There are many effects the War on Drugs has had on our society, and most of those effects are not going to be known until the War on Drugs ceases to exist.

USSR was anything but fair, and that's why people ran away from it whenever they could; and that's why when USSR fell nobody shed a tear for the venerable Communist Party. CPSU wasn't even good at the only thing it pretended to do - to rule the society. Ask anyone who lived in USSR and you will be told all kinds of tales.

Same thing with AGW, after a destructive hurricane or storm. There is never an "ideal time" to report study results. People who disagree should respond to the substance of the study, including its methodologies and perhaps on the legitimacy of the data. Not "gee why alla sudden so much interest in this seems funny doncha think?"

Since you bring it up, check out the recent FOIA documents obtained by Judicial Watch regarding Mayor Bloomberg's organizations actions in the hours following the Sandy Hook shooting. Specifically, look for this email, sent just after midnight, where they discuss what legislation to try to ram through in the aftermath. There's a good analysis here. Turns out, there really are conspiracies by gun control and anti-drug organizations to "leverage" high-visibility events to "surf in blood".

You assume it's natural and moral that basketball players earn millions and beer sellers earn little

It is natural. There are very few people who can play top-level pro basketball. By definition, the best are chosen for their skills on the court, their ability and willingness to work with the team and coaches, etc. Far, far more people (billions of them?) are able to carry trays of beer around. Someone setting up a business to entertain crowds of people by displaying highly skilled competitive team athletics and serving them drinks have to do what they have to do in order to attract the right people to perform those tasks. Why would an athlete spend all of that time and energy working out, practicing, risking injuries, and all the rest if your preferred system would prohibit the team from paying them more than they'd earn for doing a job that requires less effort, no commitment, and which almost anyone could do?

And it's moral. Because the alternative is someone like you dictating what each skill is worth, or dictating that everyone must earn the same no matter how good or rare their skills may be. That you've swallowed that notion as preferable to two people arriving between themselves at an understanding of what a given effort is worth - that's pretty awful. People like you have ruined entire societies, and murdered hundreds of millions of people to hide the fact that dictating relationships between buyers and sellers always fails.

The super rich also make almost all the money. Those 50% you're talking about are poor people. The amount they're making for a days labor is less than it was 30 years ago, even as the super rich demand a larger share of the profits because they can't.

It's astonishing to me that people like you are so stupid as to not realize that the take home pay for the lower classes hasn't increased to any meaningful degree since sometime in the '70s and that thanks to the economic policies that coddle the super rich, the poor can't even afford to save money as inflation always wipes out the interest on that savings..

It mostly has to do with the continued prohibition in the rest of the country and the fact that the shops are forced, by law, to deal in only cash. If the local Target had to cart around an entire day's worth of revenue, entirely in cash, they'd be the target of these thugs also.

An illiterate worker at the factory was earning more than a scientist.

I am a scientist. Would I change my job to factory work for any increase in my pay? Hell no, even if you offered millions of dollars (billions, if I had to forfeit reading). I do science because it's fun for me. If the scientists actually had it worse off than illiterate factory workers, they could have just played dumb and gotten the "better" job (a lot more easily than someone could go the other way). In a just world, people with boring/exhausting/little-better-than-a-machine jobs should be paid more than those privileged with the ability and opportunity to do fun jobs. Corruption and cronyism for political insiders is a different matter --- but there's nothing horrible about less fulfilling jobs compensating by paying more.

Re:Reefer madness?

[tftp]

This was a very familiar situation in USSR. I was an engineer there, not a worker. However my father, an experienced doctor, at some point said "enough is enough" and quit his medical field altogether. He got a job at a salt distribution warehouse, to carry sacks of salt from one place to another. His pay increased twice, if not thrice.

You are right, of course, that many scientists (all over the world!) work not for money but for fun. They love their work. However... this recipe is only good if you are all alone in the world. You'd be perfectly happy pushing the boundaries of knowledge from 9am to 5pm (or much later) and then returning home, in your little single room, which doesn't even have a bathroom or a kitchen - you'd share those with people who live in other rooms. You'd never invite a girl to your room, firstly because no girl wants a poor scientist, secondly because you cannot entice her to visit you in that shared apartment, and thirdly you will not want all your neighbors to discuss your friends. But since you are single (forever!) this is not a concern at all.

Fortunately for demographics, such people are not very numerous. Most people are interested in families and children. They want their own apartment, their own car, and their own country home (dacha.) They do not want to live on pasta 364 days per year; they need clothes for themselves and for the children, and toys, and things, and vacation in Sochi. All this requires money (and knowing people who will sell you what you need; remember, stores are empty.) The meager salary of a MNS does not pay for any such thing. Eventually the wife spells out the offer that cannot be refused: "Get a real job and be a real man who earns money for the family. Or else." However displeasing such words can be, they do make sense. Some people - many! - surrender to the inevitable, abandon their scientific or engineering - or medical - careers and become lowly workers. All this is because workers were paid FAR MORE than specialists with several years of university education. You can see for yourself how disastrous such a policy would be for any country. Why was it in place? Because USSR was, officially, a state of proletariat; the "intelligentsia" (all those scientists and engineers) were just fellow travelers that had to be tolerated because they are useful.

I can write books on this subject, as can anyone who grew up in USSR. You cannot simply apply logic and derive an answer - USSR was actively and aggressively defying logic for sake of political dogmas. The facts on the ground are just what they are, and not what an educated and friendly foreigner (such as you) would think they are.

Re:Reefer madness?

[Anonymous Coward]

Apparently, the Russian technocrats' estimates for "sufficient" pay to keep scientists happy can't have been too far off the mark --- after all, the USSR kept apace of the West in scientific development (and often in the lead). So, there must have been enough scientists happy enough with their lot not to take the "easy way" out, tripling their pay and cruising to an easy life of handouts. Perhaps not the perfect ideal --- on the other hand, better than a society where tens of millions of workers live in conditions worse than you describe. Considering what a near-minimum-wage salary buys you in most of the US, having an apartment of your own, and a car, and a vacation house, is entirely out of the question (much less supporting a family on a single salary, even at 80 hours a week). In the overall balance, I'd consider it a more just world where an ordinary worker can support a family in decent comfort (increasingly impossible under the US plutocratic system), while enough people are willing to trade away domestic satisfaction for the joys of higher work.

You say these policies were disastrous for the country --- but where is the evidence of that? The USSR did not, in the big picture, seem to particularly lack for expertise in advanced mathematics, physics, and technology, especially given their relatively lower pre-revolutionary level of economic/industrial development compared to Europe/US. Of the many systematic failures resulting in the USSR's inability to bring about a "workers' paradise" and eventual collapse, was "lack of eager participation in scientific fields" really so disastrous?

Re:Reefer madness?

In one word, yes. In many words, a country doesn't have to have science. I haven't heard of many Kenyan or Mongolian scientists; but those countries exist and are viable enough. Science is needed to improve the world. A side effect of that is increased wealth of the population, and presige, and influx of students, and many other things. A country without science will be a mere consumer of goods that others invent and produce. Such a country is lucky if it has something (natural resources) to sell in exchange for other countries' math and drawings and ideas. Many countries have nothing to sell; sucks to be them.

Apparently, the Russian technocrats' estimates for "sufficient" pay to keep scientists happy can't have been too far off the mark --- after all, the USSR kept apace of the West in scientific development (and often in the lead)

Those had many causes. But good salary was rarely one of them. First, as you say, people were willing to make sacrifices. Secondly, at the top of the pack Academicians were paid well. Thirdly, some science was so important (nuclear, spaceflight) that no money was spared. Unfortunately, the downfall of all that began under Brezhnev, and by 1990's the process of decay had completed, with research facilities standing empty, and renting space out to newborn capitalists who used rooms where chemical labs used to be to simply mix electrolyte for car batteries. Did you notice the mass exodus of Russian scientists around that time, when the mechanism of exit visas was loosened and then removed? Did they escape their country because it was good? No, they escaped because they couldn't survive on scraps that the government threw them, and because they couldn't do any science because there was no money to buy equipment or visit conferences. All they could do is to sit in their old labs and drink alcohol. Some chose that path; those who were younger and who had future ahead of them, they found jobs abroad and left as fast as they could.

Note also the positive feedback loop here. As scientists and engineers run away, whole factories become unable to manufacture complex goods. Those factories close, and replacement goods are brought in from China. This results in disappearance of competent workers - and the resulting domino effect wipes out the whole industry. This can be seen in the USA as well - hard to assemble product A if all its parts B, C and D are not made locally. That's how nearly all computers are assembled in China (Taiwan.) Do you think there are workers left in the USA who can work a steel mill? Hardly anyone, outside of gray-haired old-timers, can work on a lathe or on a milling machine and produce accurate, high quality parts. I work with machinists, and I know who they are - a dying breed that lives on small orders from startups from Silicon Valley.

on the other hand, better than a society where tens of millions of workers live in conditions worse than you describe.

Conditions of life in USSR were markedly worse than conditions in the West. Salary of an experienced engineer was, say, 2400 roubles per year. A new car (if you can get one!) costs 6000 roubles. A condo costs about 10,000 roubles. Compare to US realities. An engineer would be getting, say, $50K/yr. and he can get a new car for $15K, and a condo for $40K - just by walking into the sales office and giving them the money. In reality, US people were very, very poor. You can compare them to americans on social security - they both get just enough to live in housing of minimal quality, and to buy food of minimum quality. While that may be fair to some workers, scientists and bright engineers do not want to be poor, and they know that they can do better. Why, in your opinion, Soviet people ran to the West at the first opportunity, but the opposite was hardly ever

Uh, no. It's because Obama's DOJ has made it clear that legal marijuana shops cannot use banking services. Including armored cars.

I'm related to someone who does research on this topic. There has been a lot of research over the last few years about how marijuana may make people paranoid or have an effect on various mental illnesses. The evidence so far seems to show that prolonged heavy use really does cause problems. Unfortunately, the researchers do have issues getting research subjects because heavy marijuana users tend to think the researchers are government agents running a sting operation.

What you are suggesting is that pay should be decided by supply and demand. That's a feature of capitalism, it's not "natural" by any stretch of the imagination. That you think it is is simply a symptom of you having grown up in a capitalist system, and not having the imagination to see that it's only one of an infinite number of possible systems.

In the 1980s, the peak US military spending was 8% of GDP. OTOH, the Sovs pumped 15-17% of GDP into it's military.

But, you say, the US had/has a much larger economy than the USSR (and now Russia)... sure, because capitalism generates more wealth for more people than communism.

Re:Reefer madness?

Quite. The USSR had to spend a much higher proportion of it's smaller GDP to keep up with American militarism. That's what bankrupted the state, not communism.

America having a bigger GDP than Russia doesn't mean America's political system was better. Just that their GDP was bigger. You don't somehow believe that if both states were capitalist they would have equally sized GDPs? Of course not - different countries have different sized GDPs.

In a decade or three, China with it's non-democratic state capitalism will have a greater GDP than the USA. Will you then believe that non-democratic state capitalism is superior to American capitalism? And is therefore "natural"?

China with it's non-democratic state capitalism will have a greater GDP than the USA.

Per capita GDP will still be much lower. When Chinese state capitalism generates a per capita GDP that's as high as that of the US, then that will be an indication that such an economic system distributes wealth as well as the US system.

Larger doesn't mean fairer.

Larger implies fairer, because "fairer" generates "larger".

Pretty sure I don't have to believe any such thing. What do I believe (without any evidence, mind you) is that people suffering from psychosis may not provide reliable data - especially when it come to recalling details from 5/10/20 years in their past.

Look, patient reported data - the sole basis of this study - is notoriously inaccurate. Patient reported data among a population that is recovering from a psychotic episode is less accurate still (psychotic episode being defined as "a loss of contact with reality") . These researchers are reporting these inferences with 95% confidence with a sample size of 410. Correct me if I'm wrong, but doesn't a 95% CI with a sample of 410 imply some level of accuracy in the source data?

Re:Source data for this study?

You're wrong! The point is that we start with the default assumption that all groups will provide EQUALLY inaccurate data, both psychotic people with a history of heavy pot use, and psychotic people without that history.

Here's a simplified example. Imagine if everyone, when asked their height, gave an answer with errors of up to two whole feet (i.e. terribly inaccurate), and that people in general overestimated their own heights, but both men and women have the SAME kinds of errors in their reported heights.

Now survey 410 people at random about their height. You won't get correct average heights. But you will get correct the correct DIFFERENCE in height between men and women, about 6", with a high degree of accuracy. That's because of the assumption that everyone provided equally inaccurate data, and so the inaccuracies cancel out.

When are they going to study why I and most others like me have smoked pot for four decades, while being productive members of society all that time without succumbing to the Reefer Madness Syndrome?

What percentage of pot smokers who don't partake in other illegal drugs are mentally ill? I would guess that the difference between non-smokers would be negligible.

I dealt with surveys at work maybe fifteen years ago (maybe more).

Think Sheldon). And yeah, believe me, they know how trustworthy these people are, it's accounted for in the math (which is over my head).

Re:Source data for this study?

Can you think of another way to research this kind of thing?

It's not like you're allowed to kidnap 5000 toddlers with mutations that give high risk of psychoses, dump them on an island, and feed exactly half of them hash brownies every day to find out which ones crack up first.

The data in this study likely no less reliable then the data in a study of when non-mental patients start smoking pot. They're under treatment, so presumably they're in touch with reality, and even when they aren't under treatment folks with mental illnesses are not that much more likely to lie then the rest of us sketchy motherfuckers.

It's pretty clear there's a link between weed a major mental issues (particularly schizophrenia). What's not clear is which way the causality goes. Are schizoes self-treating with weed, or is weed driving people schizo? This is a very cheap way to shed some light on the problem without violating any ethical standards.

It gives some weight to the weed-driving-people schizo camp because when most of these people started smoking pot they had no symptoms. It's not conclusive -- perhaps a mind that hasn't undergone a psychotic episode of some sort feels "wrong" and it's owner tries mind-altering substances to fix the problem -- but it is a very interesting data point.

Re:Source data for this study?

One can have a psychotic break with reality, and then come back to sanity, particularly with the very good antipsychotic drugs we have these days. I doubt they gave them surveys during their psychotic episode, but after they were treated.

It's like the disclaimers that vitamin and supplement sellers use to disclaim a bunch of claims they just made. If you say a bunch of stuff then claim you weren't actually saying anything, you have zero credibility in my book. "It is still unclear whether there are safe levels of use for cannabis" is a pretty curious statement coming from someone who isn't even studying whether there are safe levels for cannabis use. She's right, but that declaration in this context is misleading, at best. It would have been just as relevant to say that the first piano-playing, pink African elephant may or may not be discovered by elderly New Jersey construction workers within the next decade.

PROHIBITION is the cause of Ultra-Low CBD Cannabis

[Anonymous Coward]

Cannabis itself and smoking daily is not the issue.

The issue here is that the pressures of prohibition have caused the breeding of cannabis to produce ultra-high THC strains that have little to no CBD at all. CBD is the cannabinoid that counteracts the 'psychosis' factor of THC.

Eat too much Marinol and the same thing happens. Too much THC with no CBD.

I have an article covering this very subject at thecleangame .net /2013/10/prohibition-causes-psychosis/

But I guess your average slashdotter would assume 'pot' was for good old Mary Jane.

Worthless and inconclusive research, I'm afraid...

[bogaboga]

And this is because this research doesn't answer the following question:

Can we be sure that even though psychosis manifested itself earlier in the subject population, it (psychosis), still maifested itself later in this particular group?

In otherwords, can we be sure that pot use in this specific group didn't delay psychosis even though on average, psychosis came earlier as compared to the other group?

I know of folks who use pot daily. They are now in their late 90s. One could argue that pot is responsible for their delayed psychosis if at all, no?

Yes ! We're getting close to an answer here

[Anonymous Coward]

Cannabis use skyrocketed in the last decades, but the psychotic disorders prevalence curve didn't follow the weed consumption.
Yet, doctors still see weed-induced psychotic episodes. Patients are smoking more than the general population, and those who smoke usually smoke a lot (I'm a med student I've seen this myself).
So doctors are still wondering what is the impact of cannabis use, and the main hypothesis in the medical community is that it hastens the onset of the disease and makes it more severe.
I have nothing against people who smoke weed. A lot of my friends smoke. A lot of doctors smoke during parties, gatherings, etc. But, when it comes to doing your job, you look at the patient's habits (what they eat, what they drink, which substances they use) and you see that nearly half of the patients smoke weed regularly?! Well you HAVE to look for answers if you want to help your fellow human being.

Re:Yes ! We're getting close to an answer here

[Anonymous Coward]

i wonder what the relationship between marijuana use, lsd use and psychosis it. Smoking weed was fun until I did a lot of acid one summer, then after that smoking weed would take me back to that really insane lsd place instead of just the funny dopey weed place...i love lsd and think it's great but to really get the most out of it you have to take a large does but only do it rarely. The little daily mini-trips weed started causing me was getting really mentally unhealthy. No matter how insane lsd gets you always know in the back of your mind in a day or two everything will get back to normal and you can live again...but if you keep on smoking weed constantly "normal" doesn't quite come back.

Re:Yes ! We're getting close to an answer here

[NicBenjamin]

Cannabis skyrocketed recently?

Hate to spoil your image of your parents, but the skyrocketing in weed use happened back in their day. My Dad has this great story about the time he got drunk/high and mailed a death threat to the White House (in his defense, it was Nixon). Granpa made it go away with a meeting with the FBI in the state capital. In the middle of it he realized there was a joint in his pocket.

Since the pre-weed-avaliability days were also the everybody-thinks-lobotomies-are-good-therapy days it's really hard to figure out whether we have more psychotic episodes post-weed.

That is nonsense. It only is thorny if you plan to take "war-on-drug" type actions if such a relation is confirmed.

The thorny part mostly being the fact that we seem to be highly selective in our choices of unhealthy behaviors we choose to vigorously combat.

Alcohol

[Anonymous Coward]

Alcohol usage is also tied to an earlier onset of psychosis.. It is almost certainly the general substance induce brain chemistry change, which might simply causally show an earlier psychosis onset. But that does not indicate the various product *causes* the psychosis. It only shows an underliyng problem earlier.

Re:Alcohol

[YttriumOxide]

But that does not indicate the various product *causes* the psychosis. It only shows an underliyng problem earlier.

Psychedelics are also like that.

There was significant research performed in to whether psychedelics can directly cause psychotic episodes (as anecdotally reported on more than one occasion). It was found that in people with a known predisposition for psychiatric issues (or people with existing psychiatric issues) that a psychotic episode brought on by psychedelic use occurs in a fraction of a percent (sorry, I don't have the research in front of me to look up the exact figure). In people with no known predisposition, there was only one case (out of a very large number; again sorry, no exact number right now) where a psychotic episode occurred. This was in a person who happened to be the twin of a schizophrenic; so it is considered likely that they did in fact have a predisposition that simply wasn't noted.

What if that's mixed with aspirin and some of other "herbal" stuff people can buy from any Wal*Mart to try and self-medicate their problems?

People should know the effects of marijuana by now. If you ingest it every day there are probably consequences. It's not a secret. It's been pretty well documented

People don't know what 300% vitamin B / guarana / ginseng / whatever does over 20 years though and they probably never will. But that's okay somehow because those things are regulated.

Some noted pothead psychos

Propaganda from Team Tony Blair

[Anonymous Coward]

When Blair first came to power, he tore up the entire existing power structure in the UK, and placed his loyalists at the head of every significant body, political, social, religious, business, etc. Today Blair's iron grip over the UK makes Putin's grip of Russia seem laughable in comparison.

Blair uses various forms of social theme to bond his lower level operatives- people frequently trained and recruited via Blair's COMMON PURPOSE organisation. One of these themes is a strong bias AGAINST cannabis use. This has nothing to do with whether pot is good or bad, safe or dangerous. This is a theme used to bind certain types of 'useful' idiots that are found in present day British society. You see Putin doing the same thing with so-called anti-homosexual initiatives (actually Putin's Russia is FAR friendlier to gay Russians than any previous regime). But Putin knows the anti-gay sentiment is strong in various types of people that are useful to recruit to his cause, so he exploits the mechanism while strongly believing the opposite.

Britain has long fallen prey to what are known in the UK as the "CHATTERING CLASSES". This means people of significant societal influence (when considered across their total numbers) who love to DRIBBLE on and on about the latest 'concern' of the day. Media campaigns whip these morons into a frenzy of "we must do something about this" activity.

North Korea famously has pot use completely legal- for the same 'reason', Blair wants the UK to actually have pot use more 'CRIMINAL' than before. You see, it isn't about the 'use' of cannabis, but the response of the sheeple to the THOUGHT of cannabis use. In the UK, making the use of drugs a political football is like putting grit on a road- it creates more political 'traction' for team Blair- traction Blair can use to advance the agendas he really cares about- like a massive expansion of Britain's police State, helping lay down the frameworks needed for Blair's goal of a new World War.

Reefer Madness

[FredGauss]

There has been evidence of this association floating around for ages. On the balance of evidence there may be reason for concern, but in particular as with anything in medicine, the right decision for any individual may come from presence of the right (or wrong) risk factors.

See e.g. : http://www.sciencedaily.com/releases/2012/11/121114083928.htm http://www.forbes.com/sites/alicegwalton/2012/01/11/the-neuroscience-of-pot-researchers-explain-why-marijuana-may-bring-serenity-or-psychosis/

One factor that would seem to be relevant is the proportion of THC and cannabidiol (http://en.wikipedia.org/wiki/Cannabidiol) present in plant strains, and change in ratios from decades past as plant breeding has changed the landscape of what effects may be expected from a particular plant.

The extreme reaction of "Reefer Madness" is almost certainly misguided, but there is reason to suggest that more science is needed towards ascertaining that the full benefits may be had, and risk factors removed (e.g. via genetic tests and controlled breeding/testing of plant strains) whether for medicinal purposes or otherwise.

[gestalt_n_pepper]

Illegal drugs make it easy for the police to plant evidence and pick up anyone at any time. The high prices that result from the illegality keep the cartels in business, which in turn, keeps congressional campaign coffers funded.

When I smoked pot in high school, it was fairly intense and scary, and I never had the slightest desire to use it every day. I would wonder whether people with early signs of psychosis simply find it less strange and less frightening. Simply not as different an experience. By analogy, Eskimos don't necessarily enjoy the cold more, but might be less likely to be alarmed at experiencing cold. Kids who have been spanked tend to be less afraid of being in fights. Kids whose brains behave weirdly are less likely to fear mind altering experiences. Etc.

Mental Health and vested interests

[John Allsup]

It's well known that Mental Health is dominated in many ways by vested economic and political interests.  It would be nice for the anti-drug lobby if research showed that drugs cause MH problems, so there is funding for that.  It would be nice for Big Pharma if clinical trials show their next wonder drug works.  Thus funding appears for such trials, and the ones with the desired results get published whilst others get shelved (though they need to take care not to make this too obvious).  Then occasionally (like Western Lapland), things get done differently, with better results than the medication heavy Western approach, and do the medical science research community clamour to reproduce and investigate?  That is not to mention the occasional meta-analysis that correlates a drug trial's sponsor to the best remedy in the trial...  Pot is a bogeyman for politicians to campaign against, and isn't a moneymaker for Big Pharma, nor can it be patented, so it's in their best interest if as much anti-pot research is produced.  Basic politics and economics when you get down to it, and the 'science' bit in medical science needs to be take with a truckload of salt when it comes to Mental Health.  Health in that context also needs a similar dose of salt, since drugged-up zombies with no motivation, poor physical drive, poor quality of life and a chemically supressed emotional system that can't drive them hard enough to do something about it... are deemed to be 'well, compliant with treatment, etc.' whereas someone with better physical health, who is motivated to get on with their life, but doesn't rely heavily on strong tranquilising drugs often has this non-reliance put down as a 'risk factor'.

Re:Mental Health and vested interests

[Xest]

"Pot is a bogeyman for politicians to campaign against, and isn't a moneymaker for Big Pharma, nor can it be patented, so it's in their best interest if as much anti-pot research is produced."

I've seen this said on Slashdot a couple of times but I've never had it explained. What is special about pot over say, bottle water, that you still couldn't build a brand around it? Why are certain strains of cannabis plant not patentable in the way every other plant is? What is preventing big pharma from producing their own patented strain and marketing it with their own brand?

Sorry but "big pharma hates it because it's not profitable" seems to be a conspiracy theory and nothing more. Big pharma seeks to gain massive profits from engaging in producing their own branded version of the stuff using a perfectly patentable strain of the plant (it's well established in law that you can patent strains of plants).

I'm not arguing with the rest of your point but I've yet to see this big pharma conspiracy theory padded out and explained and it's contradictory with both what the law actually says, and how business actually works. You could use the same argument to suggest Coca Cola wants water banned because you can't patent and make money off of selling water - they do, bottled water is big businesses and complements their fizzy drinks business well.

Yes and no...

[f3rret]

While I am all for legalizing it, the article does have a point.

I recall at least one British study looking at the link between cannabis and psychosis that found that strains with a high THC/other canabinoids ratio would cause tests subjects to score higher on at least one standard test questionnaire for psychosis, while subjects injected with a more 'natural' blend of THC and other canabinoids would tend to get a psychosis score not much different from them being sober.

The conclusion as I recall was that there is some evidence that strains bred specifically for a high THC content could be more likely to cause psychotic event or temporary psychosis-like states.

Well first off, most "synthetic weed" isn't really THC or any of the other naturally occurring cannabioids. they're usually fully synthetic chemicals that never were anywhere near an actual cannabis plant. From what I hear, their effects aren't much like a normal cannabis high.

That said, the study I mentioned never looked at the synthetic stuff, it only looked at the (possible) link between high THC content weed and psychosis to a more natural mix between THC and other cannabinoids.

My hypothesis is that the reason we're seeing these new super skunk strains with ultra high THC contents is because reagent tests that allow you assess the THC content in your plants have become more widely available, allowing for more focused breeding towards higher and higher THC contents; and this might turn out to be a bad thing, because if you watch the video in my original post a pure THC trip kinda looks like it sucks while a more natural mix produces what looks like a quite enjoyable experience.

Likewise, you could argue that pot actually prevents psychosis. You could argue that pot extends life. You could argue that smoking pot daily is a psychosis in itself. You could argue that nobody ever landed on the moon, and that Elvis is still alive. Most people would probably recognize you as someone who just likes to argue for the sake of argument though. Certainly nobody would take you serious, since you have no data to corroborate your argument, and your argument implies that everyone eventually gets a psychosis (which is demonstrably false).

Re:Pot?

Not really, no. It seems that pot has been getting stronger and stronger over the years. This is probably due to the results of prohibition: you need less of stronger substances making the same amount of active ingredient easier to smugglee and hide.

Plus, agriculture has improved since the 60s and people have been using the knowledge to breed more potent varieties.

Seriously wtf are you talking about "rationalization". Rationalization of what? It makes no sense since I wasn't making an argument for anything based on whether pot has got stronger or not.

Re:Pot?

[strikethree]

I quit smoking not too long ago, I had sweats, irritability, and sleeplessness for ~2 weeks

There are no physical qualities concerning marijuana and/or THC which would cause that. If it did indeed happen, it was purely mental on your part. These symptoms are not frequently noted as being suffered by others who have stopped.

this isn't 1960's pot.

Nice FUD there... which calls into question the veracity of your prior testimony. So people in the 1960s had to smoke more to get the same effect as people today. So what? You do not drink the same amount of hard liquor as you do beer. Why would you smoke the same amount of current strains as you would have with prior strains?

Albeit I don't smoke pot, I can sort of relate to this. Let me see now...bipolar, slightly psychotic at times, paranoid as f**k, loss of reality? Check! Hey, maybe I really SHOULD smoke some pot once in a while, what do I got to lose?

Re:Heh, sounds like me in a nutshell.

[Anonymous Coward]

I'm an AC because I'm not as brave as you, but I've never smoked anything in my life. I also have depressive type schizoaffective disorder, or more controversially, schizophrenia and major depressive disorder. If I inhale second-hand pot fumes---say like, at a concert---I go into psychosis. My body is *that* sensitive to THC.

Therefore, I avoid events where cannabis is smoked like the plague, because psychosis is not a particularly fun state to be in. I can always go up on my medications to calm my brain down (risperdal, klonopin), but the side effects of those medications are terrible. I'm trying to make my way through college and high doses of either of those drugs make me as dumb as a post. Not particularly a good fit for my dream of getting a Ph.D. in Electrical Engineering.

When my neighbors smoke cannabis in their bathroom (I live in an apartment), the fumes get in through the shower vents and my mind starts to race like you wouldn't believe.

What I find interesting is the debate about gun control with the acceptance of cannabis. Many people seem to link gun violence with mental disorders, so if we get more mental disorders, are people sewing the seeds of more violence and tragedy? It's a question society will have to come to terms with one way or the other.

...and I have nothing against mairjuana... ...the modern world is all about risk evaluation. If there is a correlation between smoking more cannabis and being more psychotic, workplaces etc. are more likely to select those who don't smoke cannabis. Whether cannabis is causative or merely indicative is irrelevant.

It's the same problem as racial profiling, personality testing, IQ testing, and so on. It's not that these tests confirm a basis for anything - they just hint at the outcome. It's particularly insidious because if you are biased against a certain group of people, of course they're more likely to fail.

The science vs. epidemiology of cannabis

[The Real Dr John]

This is another in a series of basically poor quality epidemiological studies attempting to link cannabis use to various psychoses such as schizophrenia. There is no link, and this study is not a scientific investigation into any such link. This is simply an epidemiological study (attempts to correlate environmental or other factors to various disease states in a population). Psychoses such as schizophrenia are not caused by drug use, and the authors clearly know this. Schizophrenia, which is the most common cause of “psychotic episodes”, is a neurodevelopmental disorder that as far as neuroscience can tell is a disorder which people are born predisposed to both genetically and probably during very early development (long before any cannabis use occurs). Cannabis works on a brain neurotransmitter system known as the endocannabinoid system for which there is a major neurotransmitter in the brain known as anandamide. It is involved in various brain functions ranging from hunger induction to anxiety to pain sensitivity. Activation of this system results in increased hunger and decreased anxiety and pain sensitivity. So there are very clear reasons why some people use cannabis other than just to relax. The science of the endocannabinoid system is still being worked out, but clearly cannabis is one of the least harmful drugs known to mankind. Compared with the clear and present dangers associate with alcohol and tobacco use and addiction, it is a wonder that these types of studies get so much attention in the press.

Transgenic Marihuana and Consumption

[chanio]

Studies of pot today should consider possible side effects of consuming transgenic marihuana. Who knows for sure that there is no side effects with it, compared with the pure and old herb?

Besides, today, use and consumption are not well differentiated words.

Antient cultures used to consider drugs as gods. They might have had less technical knowledge about science, but that should not diminish their knowledge. They used it on special occasions.

If today we use or consume drugs in a similar way as we 'use our actual gods' to get something back from them.
If we consume drugs to patch other existential problems that we need to solve. Then the god part of the drugs might act against us...

Like using guns. Guns are not good or evil. But they might become so, with our use.
The myth of drugs that started with inquisition should finally end.
Drugs have been part of the human existence since the begining of time. And forbidden or not they shall allways be part of us.

You sure?

[bussdriver]

You must not have done much. I knew pot heads; they were into it enough to know that not all Pot is the same and that a lot of Pot is NOT 100% pure. You may not have had the actual thing; it can come laced with other things. Some of these guys ended up into the other stuff later but not because Pot was the stepping stone; if anything was it was Tobacco, every single one I knew started with Tobacco. It was likely the laced stuff that got them into things they knew were dangerous (beyond Tobacco, contrary to what adults think, teens can reason beyond binary extremes... if anything it's parents who think in binary.)

Again, these problems are mostly solved by REGULATION. You don't have hard drugs laced into your Tobacco or Alcohol. Plus if somebody developed a tobacco plant that was foobar it wouldn't get into the regulated market and probably fade out of existence...

I never ever wanted to alter my brain chemistry, so I've not touched the legal (and more harmful) drugs. Plenty of opportunity and peer pressure; so I'm not some sheltered pious wimp like the non-hypocrites on the opposition.

Worthless != Not comprehensive

[Anonymous Coward]

Just because a study does not answer all the questions about the association between cannibas use and psychosis - in fact it probably raises more questions than it answers - does NOT mean it is "worthless research".

Scientists need to establish some directional parameters just to be able to justify research into follow-on areas. This IS the scientific method, NOT "prove to us from this one study that you have established a direct causation beyond any doubt."

Pot could become more dangerous than tobacco

[140Mandak262Jamuna]

Tobacco when it was first used some 400 years ago was much less addictive than it is today. It is legal, companies have been using all the scientific methods available to them to enhance the addictiveness of the product to sell more of it. Progressively the nicotine content increased. I know of people who have kicked all other habits including cocaine but were struggling to kick tobacco.

Make pot legal, direct all the scientific research to increase the potency, throw in the possible geneically modified crops ... Pretty soon you could have a legal product, producing billions of dollars of tax revenue that is addictive far beyond what tobacco became. Those who support legalization of pot, should demand an absolute limit on the narcotic content of marijuana and make sure government does not get addicted to tax revenue from pot.

Re:Worthless and inconclusive research, I'm afraid

[Anonymous Coward]

I'd be interested in the prevalence of psychotic themes among users claiming to being targeted by the government, etc. Its illegal status alone could be contributing to the severity of these episodes. While anecdotal, I've been a daily user for 13 years, and in that time I had exactly one episode where I voluntarily admitted myself due to seeing a police car and worrying I would go to jail for being stoned and couldn't shake an intense, paralyzing fear of being arrested for possession / use. Cannabis is a mild hallucinogen, and even the high THC / low CBD strains, are pleasant trips. Now that I'm a legal card holder, those themes never cross my mind.

After RTFAing...

[jddeluxe]

I think the study was done with the express purpose of finding the indicated outcome, and statistically the sample size is insignificant and relies on non-empirical self-reporting; ergo I call B.S. spin...
I've been vacationing in Jamaica since 1980, and have a circle of friends in Negril that do in fact smoke pot each and every day of their lives. I know some people from the time they were kids until grown and others from early adulthood to retirement age.
Without conducting a "study", I can say after nearly 35 years of observation, the net effect of long term daily pot smoking would appear to be nil; people that are stable /unstable, crazy/pretty sane, serious/non-serious all seem to maintain their individual personality traits long term irrespective of their ganga usage.

I dunno

[Anonymous Coward]

I might panic when I start running out of weed.

I quit too actually. I don't know why. I started doing pain pills instead and they don't make me high. I just kind of take pills to feel normal in my old (er) age these days. I am relatively young and don't have a child of my own.

Lately here I rely too heavily on my Dad but I think he probably might have more than he can spend and I will have to get my stuff together here if he needs in-patient care someday so I am taking my comfort a little now. Everything is getting so damn expensive. There won't really be anybody to take care of me. I need anger management. I wonder if I am going to kill somebody.

Who cares if pot smokers go crazy. They are going to legalize the shit sooner or later anyway. That doesn't mean you have to smoke it.

Nice try, but this study is bullshit.

[Anonymous Coward]

Pot doesn't cause psychosis. If anything, it might relax someone
who is already psychotic. But the study has managed to reverse cause
and effect.

If they wanted to blame drug use for psychotic episodes, there are numerous
other drugs which would have been much more likely to fit such a hypothesis,
such as LSD, cocaine, and meth.

Ask anyone who works as a professional in a rehab clinic. They will tell you
pot is not a problem, but that alcohol and the above drugs are.

Reefer Madness!!

[Anonymous Coward]

Re:Worthless and inconclusive research, I'm afraid

[NicBenjamin]

Just because it's not 100% conclusive doesn't mean it's worthless. Very little science in any field is actually conclusive, especially studying humans, and especially especially studying human mental health. Studying humans is really difficult because you can't do experiments.

For example, if you want to know how adolescent broken legs heal you can't just bring a hammer to an 11th grade class and go crazy. You can sit around a hospital asking 16-year-olds who broke their legs about what happened to them, but none of that data will be 100% conclusive because there's a lot you can't control for.

Mental health problems are even harder because a) they're relatively rare, b) the actual cause of most of the problems is not understood (ie: we don't know what in a person's brain chemistry could cause them to hear voices), and c) mental patients aren't easy to communicate with. Some illnesses involve actual deception, and some involve mental experiences so out of the ordinary that nobody has figured out how to explain them to people who don't have the illness, and almost all involve believing an extremely distorted reality. A schizophrenic in the midst of an episode, for example, is likely to do everything possible to convince you he's not in the middle of an episode, because if you figured out the new curtains are intended to prevent the FBI's invisible cameras from sucking out his life force you'd probably rat him out to his shrink. When he gets better he will be totally unable to explain what was going on in his head in a way you can understand.

This research is actually valuable even if the causation it implies is backwards. If people who are about to experience psychotic episodes start partaking in the marajuana because they can feel that something wrong is about to happen to their minds, and the weed helps, then it is probably a good idea for doctors who know a patient has a genetic predilection to psychotic episodes to send them to a shrink when they start partaking.

Cannabis aggravates psychosis

[Anonymous Coward]

I work in a first episode psychosis program. Clients who smoke pot require more anti-psychotic medication to treat their psychosis, and sometimes the psychosis does not completely go away despite treatment. Even on treatment clients sometimes become psychotic each time they smoke pot, and some only when they smoke a higher volume. As a person who works daily with clients suffering from first episode psychosis, I believe pot is very dangerous for many individuals. I use to smoke pot as a teen myself. I am from BC and grew up with pot smoking as a very common occurrence amongst my peers. I now feel differently, and the pot is also much stronger than when I was growing up.

I also have a family member suffering from very painful terminal cancer, who finds the best relief from medical marijuana. Marijuana is a powerful medicine, like all medications it should be used with caution and not abused.

Association is not causality

[Anonymous Coward]

Perhaps the more mentally unstable one is, the more likely one is to use drugs.

One important point to remember

[uvajed_ekil]

The vast majority of pot smokers never develop any measurable, diagnosed psychosis.

I won't whine about the difference between a weak correlation and causation, but it must be acknowledged that there is a possibility that people who experience psychosis are more likely than the general, healthy population to use drugs and, specifically, smoke marijuana daily.

There are signs that weed may exacerbate the symptoms of psychoses in some people, but that is about the only definite conclusion we can draw that links the two. That is, unless you choose to ignore science when it does not fit your agenda (we're looking at you ONDCP, DARE, and DEA).

Safe Levels

it would be in everyone's best interest to keep most of the unemployed population stoned every day to reduce petty crime... plow the money you were putting into police and prisons into treatment programs for people who voluntarily want to stop.

Be consistent, mate: if it's in everyone's best interest to keep people stoned, it's definitely not in our interest to pay for treatment programs (after which, they won't be stoned anymore).

The historical record shows that automation always creates more jobs than it destroys: there are currently more humans employed than at any other time in history. Most of them are employed in fields that didn't exist before certain enabling technologies were invented. And there has been a healthy trend away from unskilled physical labor, toward skilled employment.

Fact is, if you think the economy is bad now, it will be far worse if everyone's motivation and/or ability to performed skilled work is sacked by being stoned.

High THC

[GPS Pilot]

there is some evidence that strains bred specifically for a high THC content could be more likely to cause psychotic event or temporary psychosis-like states.

Sharpen the human genome, probably reduce overpopulation, possibly increase human happiness, and save tax money all at the same time.
