Harris Poll: Two-Thirds of US Adults Favor Legalizing Marijuana

Marijuana Poll

Chicago, IL: Two-thirds of US adults favor a repeal of federal marijuana prohibition, according to nationwide polling data compiled by Harris Research.

Sixty-six percent of respondents in a nationally representative sample endorse legalizing cannabis for adults, with support being strongest among millennials (79 percent) and members of Generation X (76 percent). By contrast, just under 50 percent of Baby Boomers (those born between 1946 and 1964) backed adult-use legalization.

The results are consistent with those of other recent national polls, including those by Gallup, Morning Consult, and Quinnipiac University, showing that a supermajority of Americans believe that marijuana ought to be legalized for adults. 

When asked whether cannabis should be legal for medical purposes, 84 percent of respondents answered affirmatively – a percentage that is also consistent with prior polling.
