For the first time in four decades of polling, a majority of Americans support legalizing the use of marijuana.

A Pew poll released today found that 52 percent of those polled said marijuana should be legal. Forty-five percent said it should be illegal.

Pew reports:

"Support for legalizing marijuana has risen 11 points since 2010. The change is even more dramatic since the late 1960s. A 1969 Gallup survey found that just 12% favored legalizing marijuana use, while 84% were opposed.

"The survey by the Pew Research Center, conducted March 13-17 among 1,501 adults, finds that young people are the most supportive of marijuana legalization. Fully 65% of Millennials –born since 1980 and now between 18 and 32 – favor legalizing the use of marijuana, up from just 36% in 2008. Yet there also has been a striking change in long-term attitudes among older generations, particularly Baby Boomers."
