Public support for the legalization of recreational marijuana in the U.S. is at a historic high—so to speak—of 60 percent, according to a new Gallup poll released Wednesday.

The results come just as a growing number of states vote to legalize recreational marijuana, with another five states casting ballots on the issue this November. Local surveys indicate the efforts are likely to pass in Arizona, California, Maine, and Massachusetts. Nevada, the final state considering legalization, seems more conflicted. (Voters will also decide on medical marijuana questions in Arkansas, Florida, Montana, and North Dakota.)

A Pew Research Center poll released last week found similar results.

Gallup first asked the question in 1969 and found that public support for legalization stood at 12 percent. It increased slightly to 28 percent during the mid-’70s, but fell back down during the “Just Say No” anti-drug era of the ’80s and wavered around 25 percent in the ’90s. But it has climbed steadily since 2000, paving the way for an increasing number of states to legalize recreational marijuana, and in 2013 reached a majority for the first time.
