Seattle Hempfest, the largest marijuana rally in the world, took place August 16-18 at Myrtle Edwards Park. Now in its 22nd year, Seattle Hempfest 2013 featured speeches from an impressive lineup of prominent cannabis activists and performances from artists such as Hed PE, Everlast and DJ Muggs of Cypress Hill.

This was the first Seattle Hempfest since Washington State passed I-502 last November, which legalized recreational marijuana. Hundreds of thousand of attendees gathered to celebrate Washington's monumental marijuana victory.

Here are some photo highlights from Seattle Hempfest 2013.
