Poll: 66% of U.S. Adults Favor Legalizing Marijuana

66% of American adults favor marijuana legalization, according to nationwide polling data compiled by Harris Research.

The poll respondents that endorse legalizing cannabis for adults show support being strongest among millennials (79%) and members of Generation X (76%). By contrast, just under 50% of Baby Boomers backed adult-use legalization, NORML reported.

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 US adults believe that marijuana ought to be legalized for adult use.

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

Arizona voters legalized recreational marijuana via Prop 207 on Nov 3, 2020. The new law allows adults 21 and older to buy, possess and use marijuana. Dispensaries with a recreational license can sell marijuana to adults.
