The Outside Lands Music and Arts Festival will allow both the sale and use of weed at this year's edition of the three-day throwdown.

California has approved a permit for the sale and on-site consumption of weed at the San Francisco-set festival, per The Los Angeles Times, as part of a test program which will also include other regional events.

"I think Outside Lands is unique in that it's a large outdoor music festival in the park—not typically where cannabis events have been licensed," the state Bureau of Cannabis Control spokesperson Alex Traverso said of the move, which was preceded by the city of San Francisco granting its own permit.

The designated smoking and vaping Grass Lands areas of the festival do have a few rules, however, including a 21 and up entry requirement. Pre-rolls, edibles, concentrate cartridges, and more will be available from a variety of cannabis providers. Edibles and weed-infused beverages are not required to be consumed within the "consumption areas" and can instead be utilized anywhere within the Grass Lands portions of the festival grounds. While Grass Lands was a part of the 2018 edition of the festival, actual smoking was not allowed.

Outside Lands 2019 kicks off Aug. 9 and will include performances by Childish Gambino, Kacey Musgraves, Lil Wayne, blink-182, and more.
