Jan. 1 was the one-year anniversary of the legalization of recreational marijuana sales in some Montana counties. In recent years, the 1929 Federal prohibition of marijuana has gradually eased as various states have legalized both medical and recreational use. Today, 21 states have legalized recreational marijuana, and another 10 have reduced penalties for possession, effectively decriminalizing the drug. Medical marijuana has been legalized in 38 states, and proponents of full legalization are pushing hard to get the cannabis issue on ballots in other states as well. While users and pot proponents are collectively cheering legalization, law enforcement officials in at least one Montana city are less than enthusiastic.
