GOP Support for Cannabis Legalization Dwindles to 40% Under Trump
The majority of Republicans in the U.S. no longer support legalizing cannabis under President Donald Trump.
After reaching an all-time high of 55% in 2023, Republicans who think cannabis should be federally legalized in the U.S. dropped to 40% in 2025, the lowest mark since 2015 (37%), according to Gallup pollsters.
The Gallup survey, conducted Oct. 1-16, included a random sample of 1,000 adults aged 18 and older from all 50 states and Washington, D.C.
While Republicans are heartened by this perceived progress, many in the party have backed away from supporting legalizing marijuana, Gallup analyst Justin McCarthy wrote. After climbing in the 2010s, Republican support for legalization had stalled at around 50% before retreating sharply this year another policy area in which there has been a reversal of Republicans recent movement toward more progressive attitudes.
