The following is an excerpt from the New York Times on a recent article titled, "Does Marijuana Use Cause Schizophrenia?"

I wonder how “closed hospitals” can be full of Black men that became insane because of smoking pot? The author, Benedict Carey, says it is common practice for Black men to be "locked up and the key thrown away" in England because of cannabis derived insanity?

The concern is focused largely on the link between heavy usage and psychosis in young people. Doctors first suspected a link some 70 years ago, and the evidence has only accumulated since then. In a forthcoming book, “Tell Your Children,” Alex Berenson, a former Times reporter, argues that legalization is putting a generation at higher risk of schizophrenia and other psychotic syndromes. Critics, including leading researchers, have called the argument overblown, and unfaithful to the science.
