In three states — Washington, Colorado, and Massachusetts — efforts to liberalize marijuana laws succeeded last night. In Washington and Colorado, the new laws enacted go even further than past efforts. In these two states, fully regulated recreational pot use has now been approved by voters. Maybe these victories shouldn’t come as a surprise. After all, in 2011 Gallup found that a plurality of Americans support the legalization of marijuana, and in 2010 fully 70% of Americans supported using marijuana to alleviate pain and suffering. What does all this mean for the four-decade-old War on Drugs?
