Seattle Hempfest is an annual event in the city of Seattle, Washington (and the world's largest annual gathering) advocating the legalization of cannabis. Vivian McPeak serves as the organization's executive director. Founded in 1991 as the Washington Hemp Expo, a self-described "humble gathering of stoners" attended by only 500 people, and renamed the following year as Hempfest, it has grown into a three-day annual political rally, concert, and arts and crafts fair with attendance typically over 100,000. Speakers have included Seattle city council member Nick Licata, actor/activist Woody Harrelson (2004), travel writer and TV host Rick Steves (2007), (2010), 2012 Green Party speaker Jill Stein, Dallas Cowboys center Mark Stepnoski (2003), and former chief of the Seattle Police Department
