I think point I was trying to make in the end was that it is the prohibition that is largely the cause of the negative elements of cannabis, by forcing it underground they are compromising on quality. I still hold true to the idea that ultimately dietary and societal factrors are responsible for causing psychosis, cannabis is simply the catalyst that accelerates the onset of psychosis. If legalised and properly managed, not by the government but by people who know how to grow the stuff, then on the other hand it could be a powerful remedy for some (perhaps not all) people who suffer from mental illness, as well as an all round panacea. Whilst I think this article provides some evidence for this argument, unfortunately it is probably not going to be taken seriously by the government (vote loser) and used as more anti drugs propaganda by the media.

That said, I'm not entirely convinced by some of the methods of research that these institutes use, and its also worth noting that many psychedelic medicines used by shamans and tribes have negative effects in the first application of treatment, its considered part of the healing process, so in a way its possibly not entirely valid to down play the effects of THC in this way. I've read accounts of LSD being used succesfully in the treatment of schitzophrenics. To be cured of illness, it is often the case that the patient must experience some suffering, and this is generally not the approach widely implemented in contemporary allopathic medicines sold by the pharmaceuticals. They tend to go for the quick fix appraoch, worry about the side effects later, where-as the holistic approach tackles the illness by facing it head on. In my view it's a more honest and effective treatment.

Insanity is reaching epidemic levels in the world today, and there is a historical argument to the support the notion that it is a natural aspect of the process of societal evolution. in that respect to attribute blame to a natural plant which has been used for the treatment of many illnesses for thousands of years seems rather absurd to me.
