Marijuana use by young people is known to precipitate psychotic disorder. Until the brain is fully developed, the risk remains. And the brain does not fully develop until about age 25 (30, according to one researcher I saw at a conference).
More and more, I suspect that “Reefer Madness” was not necessarily over-the-top propaganda.
We’re in for some rough times ahead as so many states are rushing to legalize marijuana.
Legalizing mj is nothing short of insanity.
