“Americans have changed their minds about pot. In less than a generation, public opinion has turned against the drug laws that banned marijuana, a historic shift in attitudes away from prohibition and penalties. In two U.S. states — Washington and Colorado — pot is now legal for recreational use, driving the debate about how it should best be regulated, consumed and taxed as it gains acceptance across the U.S. and in other countries. Voters in Alaska and Oregon will weigh ballot measures this year. Arizona, Nevada, Maine, Massachusetts, Montana and California — the largest state by population — may consider the next wave of pot referendums in 2016.”
