A survey released by the University of Chicago finds that a record-high percentage of Americans – 61 percent – say they support marijuana legalization. The survey uses the same wording ("Do you think the use of marijuana should be made legal, or not?") as previous Gallup surveys, which had shown a previous high of 58 percent support for legalization last October. A follow-up question found nuance in Americans' support. Twenty-four percent of legalization supporters said marijuana should be made available "only with a medical prescription." Another 43 percent said there should be "restrictions on purchase amounts." One-third of supporters said there should be "no restrictions".
