Seattle Hemp Fest is the largest annual rally in the United States for the legalization of hemp/marijuana. In recent years, it has taken place on a mid-August weekend in Myrtle Edwards Park. Since 2003, it has been a 2-day event. It was founded in 1991 as the "Washington Hemp Expo", held in Volunteer Park and attended by about 500 people. The '92 and '93 festivals were also held in Volunteer Park. The early festivals were straight-out celebrations of pot culture: the '92 festival, attended by 2,000, featured two sinsemilla plants on the stage.
