The San Francisco Weekly has a story on a new study from the journal Schizophrenia Research that proves marijuana does not induce insanity. That's good news right before a weekend. From the story:

For the new study, British investigators at Keele University Medical School compared trends in cannabis use and instances of schizophrenia in the United Kingdom from 1996 to 2005. The research showed that even as marijuana use soared among the general population, "incidence and prevalence of schizophrenia and psychoses were either stable or declining" during this period . . . The results of another clinical trial published earlier this month indicate that the recreational use of marijuana does not affect brain chemistry in a way that is consistent with the development of schizophrenia.

"Should we expect an apology — or even better, a change in policy — from the Gordon Brown regime any time soon? Or at the very least, will some sort of 'correction' be forthcoming from the mainstream news media?" asked Paul Armentano, deputy director of the National Organization for the Reform of Marijuana Laws (NORML). "I wouldn't hold my breath."
