Over the last decade, medical cannabis has moved from the fringe to the mainstream—at least in some states. Nearly 900,000 Americans were registered cannabis patients in 2017, which is more than a ten-fold increase since 2009. By the end of 2020, over two-thirds of states and the vast majority of Americans will live in a state with legal access to either medicinal or recreational marijuana.
