Pot, Now With 50% More Crazy

Bad news, dope smokers: Marijuana horticulturists, aiming to beef up your weed, have removed an element in the plant that will keep you from going nuts.

These discoveries about the link between cannabis and psychosis have been widely reported in the media, often accompanied by warnings that street cannabis has risen in strength in recent years and therefore poses a major health risk to the susceptible minority.

This, however, is too simplistic: the type of cannabis taken is an important factor. Street cannabis has indeed changed over the years. So-called “skunk” does contain higher than normal concentrations of the main psychoactive compound, a molecule called delta-9-tetrahydrocannabinol (THC). What is less well known is that another constituent, cannabidiol (CBD), has been eliminated from skunk through selective breeding to increase the THC content.
The elimination of CBD may play a key role in the development of psychosis. Laboratory studies have shown that pure, synthetic THC causes transient psychosis in 40 to 50 per cent of healthy people. In stark contrast to THC, CBD appears to have an anti-psychotic effect, at least in animals. Studies in humans, though few in number, have produced similar findings.

So the trade-off here is a really great high vs. a 50 per cent chance of developing schizophrenia? I’ll take my chances. And so will I.
