According to an online CivicScience poll of over 450,000 Americans, 58 percent of respondents support regulating marijuana in a manner similar to alcohol.
The majority of respondents reported that they would support “a law in [their] state that would legalize, tax, and regulate marijuana like alcohol”. Only 35% of respondents reported that they would oppose such a change in law.
Another recent poll of responses found even stronger support for marijuana legalization, with 61% of respondents polled agreeing with marijuana law reform.
The CivicScience survey is not a scientific poll, although its findings are very similar to those reported by Gallup in 2013, when 58% of respondents reported that they support marijuana legalization.
Furthermore, in April, the Pew Research Center reported that 54% of Americans support legalizing marijuana.
