Today, 17 states and the District of Columbia have decriminalized marijuana, four states have legalized the drug, and 23 states have passed so-called “medical marijuana” laws – despite the fact – that it is properly listed as a Schedule I controlled dangerous substance and the FDA does not recognize marijuana as a drug. Big marijuana is big business and has added Libertarians and some small government conservatives to its traditional liberal base. Public support for legalization has skyrocketed over the decades, from 12% in the 1970s to 51% today, down seven points from last year. But just as public support has grown, so has the scientific understanding of the real dangers of marijuana. Scores of peer-reviewed studies published in the last two decades show how marijuana affects the brain, heart, lungs and mental health; how marijuana has become more potent and addictive; and how it is nothing like alcohol. Join us as our distinguished experts discuss the pot business, the science behind today’s marijuana, and why Americans should oppose legalization.
