poll released by Gallup on Monday, 50% of Americans surveyed say marijuana use should be legal — up from 46% last year. This year, 46% percent said it should be illegal.
Those numbers mean that, for the first time in the poll's 42-year-history, Americans who say that marijuana should be legal outnumber those who say it should be illegal.

Societal acceptance of marijuana has come a long way since 1969, when Gallup first posed the question "Should marijuana use be legal?" Back then, only 12% of Americans favored legalization of the drug. From the '70s through the mid-'90s, support remained in the 20s, but it has been climbing steadily since 2002.
