Conservative Republicans today are the last holdouts opposing the legalization of marijuana, in contrast to the rest of the United States.

Only 29% of conservatives in the GOP say they favor legalization, according to a new poll by the Pew Research Center for the People & the Press.

This low level of support conflicts with others in their own party: 53% of moderate and liberal Republicans support legalizing marijuana.

Overall, a majority of Americans (52%) are okay with marijuana becoming legal, marking the first time this has happened in the U.S, according to Pew.

Support for legalization has jumped 11 points since 2010, driven largely by increased support from those aged 30-64. The only age group in which a majority still opposes legalization is the 65 and older cohort.

Support for legalization crosses racial and ethnic lines with a majority of whites, blacks and Hispanics in favor of changing the law.

According to the Pew poll, 48% of Americans have tried marijuana at least once, including 12% who did so in the past year. The percentage of recent use rises to 27% for those aged 18-27.

Seventy-two percent of Americans now say that government efforts to enforce marijuana laws cost more than they are worth and 60% believe the federal government should not enforce federal laws in states that allow the use of marijuana. On both matters, opinion crosses ideological lines.
