A new study by the Pew Research Center finds 57 percent of U.S. adults say they support legalizing marijuana.
A decade ago, only 32 percent of adults said they favored legalization.
The study found 66 percent of Democrats and 41 percent of Republicans favor legalization, Reuters reports.
Adults ages 18 to 35 are more than twice as likely to support legalization of marijuana as they were in 2006 (71 percent today, up from 34 percent in 2006). They are significantly more likely to support legalization than older adults.
On November 8, five states—Massachusetts, Maine, California, Arizona and Nevada—will vote on whether to legalize recreational use of marijuana.
