"Legalization won in California, Maine, Massachusetts, and Nevada, although it lost in Arizona, where it was largely considered a long shot. The initiatives that won will soon join Colorado, Washington, Oregon, and Alaska among the states, along with Washington, DC, that have already legalized pot for recreational purposes. Medical marijuana measures also won in Arkansas, Florida, and North Dakota. An initiative to expand the medical marijuana program in Montana also passed. Together, the ballot measures' eight-to-one victories mean 2016 was the biggest year for marijuana reform yet."
