Gallup first measured the public’s views of marijuana legalization in 1969, when 12% of Americans backed it; by 1977, support had more than doubled to 28%. It did not exceed 30% until 2000 but has risen steeply in the two decades since then, and is now twice what it was in 2001 and 2003…

Most politically left-leaning and middle-of-the-road Americans remain supportive of legalizing marijuana, while less than half of those who lean right favor it. Over eight in 10 Democrats and liberals, and more than seven in 10 independents and moderates, back legalization, but just under half of Republicans and conservatives do.

Views of legalization also differ greatly depending on frequency of attendance at religious services. A slim majority of those who say they attend weekly oppose legalization. Yet, about three in five of those who attend nearly weekly or monthly, and about four in five who attend less frequently, favor legalizing marijuana.
