This documentary examines the U.S. government's marijuana regulations, and how these laws have influenced public perceptions of the drug. Narrated by noted pot advocate Woody Harrelson, the film opens with a series of comically outdated anti-drug reels before chronicling America's relationship with marijuana through the decades. Filmmaker Ron Mann splices together archival footage of U.S. politicians, musicians and artists to support his weed-friendly argument.
