A new attempt to scare pot smokers in Britain alleges that smoking pot can increase the risk of becoming "psychotic." A quick glance at the data cited reveals no such correlation.

Smoking pot won't make you crazy, but trying to find the truth behind the recent rash of headlines regarding a supposed link between cannabis and mental illness might.

According to the Associated Press and other news sources, a new study in the British medical journal The Lancet reports that smoking cannabis -- even occasionally -- can increase one's risk of becoming psychotic. It sounds alarming at first, but a closer look at the evidence reveals that there's less here than the headlines imply.

First, there is no new study. The paper published in The Lancet is a meta-analysis -- a summary of seven studies that previously appeared in other journals, including some that were published decades ago. Second, the touted association between cannabis and mental illness is small -- about the same size as the link between head injury and psychosis. Finally, despite what some new sources suggest, this association is hardly proof of a cause-and-effect relationship between cannabis and psychosis,

So why the sudden fuss?

Part of the answer is political. New British Prime Minister Gordon Brown longs to stiffen penalties against marijuana users. One way to justify this move involves convincing the public that The Lancet proved that puffing the weed will make you batty. Of course, that's not what the article says at all.

In fact, investigators actually reported that cannabis use was associated with a slight increase in psychotic outcomes. However, the authors emphasized (even if many in the media did not) that this small association does not reflect a causal relationship. Folks with psychoses use all intoxicants more often than other people do, including alcohol and tobacco.

Cannabis use can correlate with mental illness for many reasons. People often turn to cannabis to alleviate the symptoms of distress. A recent study performed in Germany showed that cannabis offsets certain cognitive declines in schizophrenic patients. Another study shows that psychotic symptoms predict later use of cannabis, suggesting that people might turn to the plant for help rather than become ill after use.

Perhaps the most impressive evidence against the cause-and-effect relationship concerns the unvarying rate of psychoses across different eras and different countries. People are no more likely to be psychotic in Canada or the United States (two nations where large percentages of citizens use cannabis) than they are in Sweden or Japan (where self-reported marijuana use is extremely low). Even after the enormous popularity of cannabis in the 1960s and 1970s, rates of psychotic disorders haven't increased.

Despite this evidence, we'd like to spread the word that cannabis is not for everybody. Teens should avoid the plant. Folks with a predisposition for mental illness should stay away, too. This potential for health risks in a few people, however, does not justify criminal prohibitions for everyone. (We wouldn't pass blanket prohibitions against alcohol simply to protect pregnant women, for example.) The underground market does an extremely poor job of keeping marijuana out of the hands of teens and others who should stay away from it. A regulated market could better educate users to potential risks and prohibit sales to young people.

Consequently, the review in The Lancet suggests that if cannabis really does alter risk for mental illness, we can't leave control of sales to folks who are willing to break the law. Instead, a taxed, regulated, age-restricted market is our best chance to keep any negative consequences of marijuana under control.

Ahhh! Wowww maan. Ain't cha just craaaazy over inhaaling a little weed. Whaat bout those dudes, maan, who, didn't inhale; ya'll know 'em, those dudes that bomb babies in other countries, and, real drug factories in countries that can't fend for themselves. What's their names, Bush, Clinton, Papa Bush, and then some dudes before--Nixon (whose daughters inhaled tand just disappeared), and Johnson (who made a war to start a business for helicopters for a relative of his wife), and on and on and on.

Hey, and what about during the colonial times when it was legal to raise fields of hemp, sort of like the Elyssian Fields. Our first presidents probably all raised it.

And guess what! They didn't start wars in other countries.

Hmmm! I sort of like being craaaazy.
