Jacob Sullum summarizes a new public opinion poll (pdf) on cannabis:

Opposition to federal interference was even stronger than support for legalization. While 47 percent favored “legalizing marijuana for recreational use” and 53 percent said “the government should treat marijuana the same as alcohol,” 68 percent said the feds should leave state-legal growers alone and 64 percent said the same about state-legal sellers. These results indicate that some people who oppose marijuana legalization nevertheless believe the choice should be left to the states, as a consistent federalist would. Reflecting that tendency, most Republicans and self-identified conservatives supported marijuana prohibition, but most also said the federal government should not try to impose that policy on Colorado and Washington.
