In one form or another, marijuana legalization is coming, almost without a doubt. Four states and the District of Columbia have legalized recreational marijuana, 16 have decriminalized it, and seven allow medical use of the drug. Altogether, 27 states have relaxed their laws on the drug, and President Obama himself, speaking to Vice last March, admitted that if enough states legalized marijuana, it would be natural for Congress to consider removing it from Schedule 1 of the Controlled Substances Act—a move that would amount to overnight legalization nationwide. In March, the Supreme Court declined to hear a suit, filed by Nebraska and Oklahoma, that sought to strike down Colorado’s law. Less than a month later, Democratic presidential candidate Bernie Sanders floated the idea of de-scheduling the drug at the last Democratic presidential primary debate, and no one batted an eye.
