Because of this, drugs will continue to fund crime and do all of the horrible things they do now, except that all of the people who are currently massively anti-drugs(read the people making money off the war on drugs) will be able to say, look, we tried it your way and it didn't work", then we'll be back to the same old garbage.

    As stupid as the war on drugs is, attempting to gain the upper hand through technology is even stupider.

    For instance, thanks to the innumerable advances in creating genetically-engineered plants, we will soon see the day where the characteristics of interest in plants such as cannabis, coca, psilocybin, and opium are capable of being integrated within such ordinary plants as grass, seaweed, ferns, etc. So even if we are able to use technology to prevent drugs from coming into this country from the outside, the obvious solution for organized crime will be to make it so that the drugs can be more easily manufactured from within.

    We've already seen this with methamphetimines. By working to reduce the supply and thereby increase the cost of the more traditional drugs, the market responds with a drug like meth, that is easy and cheap to produce domestically. Look at the consequences of the meth epidemic in America. It's a total disaster.

    Changing the technology isn't the answer. Changing the policy is. Legalize drugs now.

    Who would you rather see selling drugs? Law-abiding citizens in a legalized environment who won't sell to kids? Or criminals in a black-market environment who will?

    That's the question nobody on the prohibition side seems to be able to answer. They admit that they will never be able to rid the world of illegal drugs, yet cannot come to grips with this simple question. If our drug policy is based on what is best for the children, then why haven't we legalized already? Why not start letting communities actually control these controlled substances for a change? When do we learn the lesson of alcohol prohibition? When do we recognize that there is no constitutional basis for the continuation of this goddamn policy?

      And as for deadly, heroin doesn't even come close to tobacco.

      In fact, most of the time when heroin kills, it isn't really the heroin itself, but the fact that it is illegal. This happens because the drug is adulterated, or because the correct dosage is unknown. Or because of the use of some other drug--usually alcohol--at the same time, an event that could be prevented under legalization through labelling.

      The government doesn't care about children, it cares about power. The only reason tobbacco, alchohol, coffee, and chocolate aren't controlled substances and illegal is that they were already too large in the economy and backed by people big enough to push the government around.

      Your cyncism -- or perhaps naivete -- is amazing.

      This isn't a good comparison for the simple reason that no one is really trying to prevent kids from getting access to tobacco and alcohol, and the penalties for doing so are very, very light. If the laws regarding sale of tobacco and alcohol to minors were enforced with anything like the vigor applied to less dangerous illegal drugs, I am confident that the trade would drop off very sharply. If the average apathetic convenience store clerk or unscrupulous convenience store owner knew that one violation would lead to total forfeiture of all personal assets and 30 years to life -- as it can with possession of marijuana with intent to sell in some jurisdictions -- then you could bet your bottom dollar those clerks would check every ID and not sell a pack of cigarettes with a wink and a nod.

      Frankly, I think it's worth doing and worth far more emphasis than minor problems like illegal drug abuse, which kill fewer people in a century than legal alcohol and tobacco kill in a month.

      Of course, that would only make sense if the government and the conservative anti-drug factions were really interested in public health and not using their phony drug war (like their phony terrorism war) to expand the role of state terror in minimizing dissent and maximizing profit.

When your government starts hunting for reasons to jail you, you know it's gone too far. I once read a very interesting thought on why something like this is done.

    MARIJUANA DOES NOT CAUSE RECKLESS DRIVING

    The White House Office of National Drug Control Policy (ONDCP) and certain Wisconsin legislators have launched a new crusade against "drugged driving," with a heavy emphasis on marijuana. This crusade is largely based on scientific misinformation, and it could lead to the enactment of bad laws.

    ONDCP has several slick television commercials on the subject. One shows dramatic auto accidents and two crash test dummies passing a joint while a serious voice says, "In a recent study, one in three reckless drivers tested positive for marijuana." Note the careful phrasing. The idea is to make viewers think that marijuana caused the reckless driving, without really saying that it did.

    Why would ONDCP be so coy? The answer lies in the actual data regarding marijuana's effects on driving,

    I study the effects of drugs and teach classes in the science of illicit substances, so I know this field. The plain fact is that marijuana does not cause reckless driving. Large studies of accidents show that drivers who test positive for marijuana (and ONLY marijuana -- i.e., people who haven't also been drinking or taking other intoxicating drugs) cause fewer crashes than people who haven't had any drugs at all.

    That's right, people "high" on marijuana cause fewer crashes than those who are completely sober. The findings seemed impossible to explain. It was a puzzle that made no sense.

    A bright and talented researcher in the Netherlands named Robbe recently solved that puzzle. He got experienced marijuana users stoned and had them drive around the streets of Holland. But these guys were no dummies. They drove slower, increased the distance between their cars and the cars in front of them, and never tried to pass other cars. Folks who smoked a placebo (a non-intoxicating substance made to look and smell like marijuana) drove as they usually did. Alcohol, alone or in combination with marijuana, wrecked driving completely.

    Robbe's results helped explain the accident studies. People who used marijuana and only marijuana were compensating for the drug's effects by driving more carefully. Nobody should drive high, but we can all take a lesson from these people who did: slow down, leave space between your car and the next, and don't try to pass. Unlike alcohol, which makes people behave recklessly, marijuana users tend to be aware that they are impaired and compensate with some success.

    But what about the ONDCP's claim that one in three reckless drivers tested positive for marijuana?

    It's not quite a lie, but it's deliberately misleading. The Drug Czar's no dummy. He wants to scare people, and he knows the complete facts won't do it. Instead he throws out scary but incomplete and misleading statistics - -- and hopes people won't question them. Yes, one in three reckless drivers tested positive for marijuana in a urine screen, but we don't know how many of them had alcohol, antihistamines, cocaine, or any number of other drugs in their systems.

    Legislators need to ask for the complete facts behind the scare stories before they start passing new laws based on misinformation.

    There are cheaper, easier ways to get impaired drivers off the road. Roadside sobriety tests are reliable, inexpensive, and valid indicators of impaired driving. Law-enforcement officers can learn to administer these tests quickly and easily. Unlike expensive blood tests, which can only identify a few drugs, roadside sobriety tests can detect any kind of drug im

    If I remember my chem 101 correctly, the reason this tech works is because different types of chemical bonds are susceptible to different frequencies of radiation, depending on their strength, which depends on the type of bond, types of atoms involved and their surrounding atomic environment. You shoot a bunch of wavelengths at a molecule and some will be absorbed, and in varying ratios, producing a relatively unique signature. Congratulations, you've just reinvented spectrography.

    From dyerlabs.com/chemistry:

    Atoms and molecules have only certain distinct (discrete) amounts of energy (energy levels). Relatively small amount of energy are involved in rotation of molecules, and those measurements are done with far infrared and microwave spectrometry. More energy in involved in vibrations between atoms or groups of atoms (infrared). Still more energy is involved in changes of the electronic structure (visible, ultraviolet, X-ray) and nuclear structure (gamma ray).

    Terahertz may be a good candidate from a privacy standpoint, but it's in between the not-so-useful microwave and okay-for-identifying-things infrared. So basically this is just a crippled, privacy-compliant form of IR spectrography, and they've discovered that the amphetamine-based molecules can be identified with it. This doesn't mean that other organics can be properly identified by it.

    Frankly, this seems kind of lame.
