Cocaine Vaccine In the Works
martyros writes "Researchers at the Baylor College of Medicine are performing clinical trials of a vaccine that teaches the immune system to attack cocaine, preventing it from giving a high. The vaccine is made by attaching inactivated cocaine molecules to the outside of inactivated cholera proteins. When the immune system attacks the cholera proteins, it also 'learns' the cocaine molecules as well. The result is that the immune system 'recognizes the potent naked drug when it's ingested. The antibodies bind to the cocaine and prevent it from reaching the brain, where it normally would generate the highs that are so addictive.'" An earlier story from The Star notes that human trials for vaccines against both cocaine and nicotine are well under way.
I hope this wundervacine will not attach to some of the body's natural painkillers.
Would you vaccinate your child ?

I'd like some anti-freeze to drink afterwards, please.
How would this work as an alternative to drug testing? If the vaccines for various drugs were easily obtained (say, 10 years from now), then could potential employers, private schools, and such require the vaccines instead of requiring testing as they do now? Would this be better or worse?
The orgasm releases neurotransmitters that are similar to cocaine. Perhaps those vaccinated against cocaine would never have orgasms, or reduced orgasms. In fact, dopamine is critical for a lot of enjoyment. Maybe this will spawn a 'deadheading' procedure. Piss off the wrong person or government and you will never enjoy anything ever again. You wouldn't even want revenge, there would be no joy in it.
On the other hand, a sperm vaccine would be a nice alternative to having your tubes tied. Of course, there's the nightmare scenario where this treatment latches onto a live bit of cholera or whatever and spreads, neutering all humans.

Wasn't this a subplot of Neuromancer or something, where the main character was forcibly taken away from his various addictions by having his liver modified to not process the various chemicals?

Oh, great. Cocaine prohibition produced crack cocaine and meth, crackdowns on ingredients to make ecstacy produced PMA, heroin prohibition produces all sorts of gross things, etc., etc. Cocaine is actually one of the safer stimulants out there (compared to its main rivals, crack and meth, which emerged due to cocaine's astronomical price thanks to prohibition). This insane drug whack-a-mole game is producing even more deadly and impure drugs. While we could be ingesting small and known quantities of pure marijuana, MDMA, cocaine, opiates, shrooms, and LSD, we're instead ingesting unknown quantities of who-knows-what. Most drug deaths are caused by adulterants, not the pure drug itself.
The anti-smoking vaccine, NicVax, is in phase 2B clinical testing, and appears to work. Sort of: "High antibody responders (top 30%) continued to show statistically significant abstinence at nine months: 9-Month continuous abstinence rate: NicVAX=20% (12/61, p=0.0076) vs. Placebo=6% (6/100)" That's not impressive, yet it's better than most anti-smoking programs.
Nicotine addiction is the toughest one to break. Programs for getting people off cocaine are about 40% successful. Programs for getting people off smoking are about 10-20% successful. Also, addicts tend to "age out" of cocaine and heroin addiction; after age 40, most of them eventually give it up. Not nicotine; people smoke their way to the grave.
One problem with a vaccine approach is that encourage overdoses, to overcome the antibodies. For nicotine, this is less of a problem, because smoking has a limited intake rate. But for cocaine, it's a real issue.
It's encouraging, though, that no side effects of this vaccine have been detected so far vs. the placebo.
The real promise for this vaccine is as a preventative measure. The average age for a new smoker is 13. Only 10% start after age 18. So if this works, a school inoculation program might be the way to prevent smoking.
From what I understand though, the immune system is locked out of the brain proper thanks to the blood brain barrier, so this drug shouldn't have any effect on naturally occurring opiates. My high school anatomy class never got into where the opiates are generated when someone has an orgasm (that would have made it far too interesting) but I'm guessing it's in the brain directly and not in the sex organs (where they would have to filter through the bloodstream before getting to the brain). Given how orgasms tend to be immediately gratifying, I'm guessing the production is local.
I read the internet for the articles.
There's no need for this. Not when a whole *class* of new drugs are coming out around nicotine anyway.
...never never never take a "vaccine" that has a life long effect for anything other then a pathogen or bent protein. For a basic neurotransmitter mimic? youve GOT to be kidding me, scares the shit out of me. End of story
Chantix got me off of ten years of smoking in two months, experientially, not just for while i was on it, but apparently *reversed* the entire psychological and physical process from those years.
Every other time i tried to quit i'd have to avoid bars and lounges so i didn't come in contact with ANY smoke at all. After chantix therapy, I don't have to avoid anything, *i just don't want to smoke*.
I'll leave it to you (i'm already aware) of exactly why chantix has such a powerful effect. Given, i would never never never..
CS majors know the time/space tradeoff, but they never get taught the 3rd, crucial, tradeoff of the set: comprehension!
If I understand this correctly, this will prevent cocaine users from getting high. But how does it affect the LD50 (dosage sufficient to kill 50% of the population)?
A cocaine user decides to get high after being "immunized." He snorts a few lines. Huh. Nothing. So he snorts more and more... at some point I am willing to wager he will suffer cardiac arrest or some other life-threatening problem on his quest towards getting high. If the LD50 is not much changed, this may occur pretty easily.
Also, cocaine has a very rapid onset. I am thinking it wouldn't take much to overwhelm the slower immune system response.
This is an interesting experiment as it is always worthwhile to better understand the immune system, but I think this would be a Real Bad Idea to actually implement. Unless the objective is to kill all cocaine users.
It conflicts with the business interests of a politician's donors.
Do they really think that a "vaccine" against nicotine is going to help people? If they're already addicted to nicotine for years and years, aren't they going to continue smoking and either make themselves really sick (as their immune systems attempt to fight off the nicotine) or just keep smoking away?
