My question for you, Staurm, is this: Where was anyone, here or anyplace else, attributing the blame for most insanity to cannabis? Certainly not in any of the links here or subsequent conversations. And certainly not in any external sources I've read, either. What the original BBC article and the research reported above said was that THC isolates given to those test groups at King's College and Yale University provoked increased rates of schizophrenia and/or delusional reactions, particularly in people who were prone to those problems to begin with. And the study at the University of Cologne reported that the other active ingredient in cannabis, CBD (cannabadiol), seemed to suppress those reactions in its test subjects. That's it.
