Snoop Dogg and Wiz Khalifa celebrate 4/20 at Red Rocks, tickets on sale this Friday at 10 a.m.

It's no secret that April 20 is a big day around here, and this year at Red Rocks, it's going to be celebrated by some of ganja's biggest advocates, Snoop Dogg and Wiz Khalifa. Both cats are obviously no stranger to the herb, so it only makes sense that they'll be on hand to help commemorate the biggest smoking day of the year. Tickets for the Snoop's 420 Wellness Retreat Denver, which is also set to feature YG, Smoke DZA and more, range from $59.50 through $100 for VIP, and go on sale this Friday, February 28, at 10 a.m.
