In 2012, Washington and Colorado voters made history when they approved measures to legalize recreational marijuana. Washington Initiative 502 “authorizes the state liquor board to regulate and tax marijuana for persons twenty-one years of age or older.”Since the vote in Washington, the Liquor Board has written a complex set of rules for the state’s new, legal recreational cannabis marketplace. The agency has also set limits on the amount of marijuana that can be grown. And the Board has begun to license growers, processors and retailers.For now, the Obama administration has signaled it will not interfere with Washington and Colorado’s legal pot experiment, unless there is evidence that legal pot is “leaking” to other states or children are getting access to the legal product. The feds are also watching to see if criminal organizations exploit the legal market.The first marijuana retail stores in Washington opened in July 2014.Recreational marijuana is also set to become legal in Oregon on July 1, 2015 after voters approved Measure 91 in November 2014.
