Longtime friend and fellow pro-marijuana activist Snoop Dogg will join Cypress Hill as the mainstage headliner.
Hosting the festivities is Tommy Chong of the infamous herb-burning comedy duo Cheech & Chong. There will also be an area dedicated to classic rock tribute bands with groups like Wild Child (doing The Doors), The Iron Maidens (all-female Iron Maiden cover group), Led Zepagain and others.
Of course, 4:20 marks the magic time in the day when, as tradition dictates, a special unannounced guest takes the stage.
In addition to varied musical acts, Smoke Out 2002 will also feature freestyle motocross and a pro skate team showing off their "don't try this at home" tricks.
"This year's Cypress Hill Smoke Out is very special to us," B-Real of Cypress Hill said. "Not only is it going to be our fifth annual show, but we finally get to bring it home to Los Angeles for the very first time.
"In the wake of last year's show following 9/11, we felt our fans were missing something. We have heard the voice of our fans and with that, we are challenging ourselves to make this Smoke Out live up to the respect and admiration of music fans everywhere."
Last year was supposed to mark the first tour for the Smoke Out festival. However, due to the circumstances of 9/11, that was put on the back burner and only two shows actually went on. There are already plans for a national tour in 2003.
Tickets for Smoke Out 2002 are on sale through Ticketmaster.
