Christopher Fichtner is a psychiatrist and the former mental health director for the state of Illinois. In his new book, Cannabinomics: The Marijuana Policy Tipping Point http://www.cannabinomics.com , Fichtner predicts that marijuana policy is about to change radically. As Fichtner points out, three public policy trajectories converging. The medical marijuana movement is gaining momentum. People are increasingly waking up to the fact that drug prohibition creates more public health problems than it solves. And, in the same way that the Great Depression caused people to reprioritize how we spend our public dollars, the current economic crisis has got people thinking that bringing the biggest cash crop in the US out into the open might not be such a bad idea.
