At the same time, Americans remain quite divided in their overall support for legalization of marijuana use, with 48% in the poll saying it should be legal, and 50% saying it should not be. Americans’ views are roughly the same as they were last October, but as recently as 2005, only about a third of Americans supported marijuana legalization. In 1969, when Gallup first asked about the issue, 12% supported legalizing pot.
