Voter support for marijuana legalization reached a new high as California, Massachusetts and Nevada approved recreational pot, joining four other states and Washington, D.C., with similar laws. Voters in Florida, North Dakota and Arkansas passed medical marijuana measures, pushing the number of states with such laws past two dozen. The California vote makes the use and sale of recreational cannabis legal along the entire West Coast and gives legalization advocates powerful momentum. Massachusetts is the first state east of the Mississippi to allow recreational use.
