Every year for nearly half a century, Gallup has conducted a poll to determine national support for making marijuana legal in the United States. The latest report shows the largest level of support in the history of the poll.
With voters in several states deciding this fall whether to legalize the use of marijuana, public support for making it legal has reached 60% -- its highest level in Gallup's 47-year trend.
Marijuana use is currently legal in four states and the District of Columbia, and legalization measures are on the ballot in five more -- California, Arizona, Massachusetts, Maine and Nevada -- this November. As a result, the percentage of Americans living in states where pot use is legal could rise from the current 5% to as much as 25% if all of these ballot measures pass.
When Gallup first asked this question in 1969, 12% of Americans supported the legalization of marijuana use. In the late 1970s, support rose to 28% but began to retreat in the 1980s during the era of the "Just Say No" to drugs campaign. Support stayed in the 25% range through 1995, but increased to 31% in 2000 and has continued climbing since then.
In 2013, support for legalization reached a majority for the first time after Washington and Colorado became the first states to legalize the recreational use of marijuana. Since then, a majority of Americans have continued to say they think the use of marijuana should be made legal.
A Pew Research Center poll released earlier in October showed national support at 57%, which was also a record for that survey.
