A poll put out in December by the firm Public Policy Polling reported that 49 percent of Coloradans say they favor marijuana legalization, compared with 40 percent who oppose it. Women, however, are less confident about legalization than men, with 47 percent in support and 42 percent opposed.

When California voters decided on a marijuana-legalization initiative in 2010, the last poll before the election showed women more against legalization than men. The initiative ultimately failed, despite having majority support in polls months before the election.
