According to the poll, 68% of U.S. adults support the legalization of cannabis, a small increase from the 66% in favor when Gallup conducted the same poll in 2019 but double the backing marijuana received roughly 20 years earlier.
Gallup conducted the poll from Sept. 30 to Oct. 15, ahead of voters approving recreational marijuana sales in Arizona, Montana, New Jersey and South Dakota. Voters also passed medical cannabis markets in Mississippi and South Dakota on Election Day.
The poll, which surveyed 1,035 adults, also found:
- The strongest support came from the 18-29 age group, with 79% in favor.
- Of those 30-49 years old, 75% were in favor.
- Of those 50-64, 60% were in favor.
- Of those 65-older, 55% were in favor.
Marijuana legalization was more likely to be supported by those who identified as liberals and Democrats and also those who identified as moderates and independents.
Less than half those who identified as conservatives and Republicans were in favor of legalizing cannabis.
