Ahh 4/20. A lovely, all-encompassing, festive day that pays homage to the marijuana in all of its natural glory. It has, in many regards, become an international holiday celebrating the plant.

The celebration of April 20 — and for some people anytime it's 4:20 — goes back decades. It has its roots in California, where five high schoolers nicknamed "The Waldos" used to meet and smoke weed after football practice.

Philly420 columnist Chris Goldstein wrote about how 4/20 caught fire. The spark came after an editor for High Times Magazine picked up a flyer at a Grateful Dead show.

"I'm walking out there in the parking lot and someone hands me the flyer … a half-page flyer. It had this message that people should like gather, get together, on 4/20," Steve Bloom told Goldstein.

"I showed it to all my friends and everyone got a kick out of it. Then I brought it back to the High Times office in New York. We passed it around the office and everyone got a kick out of it there too … so, I was the news editor at the time and we got some art and we printed the content of the flyer," Bloom said. "Really my little write up there in High Times was the first time the '420' probably got any national publicity outside a small network of stoners in the California area that kind of used it locally there."

Thus, the spirit of toking up and mellowing out with friends and good music would spread across the country.

Ahead of the celebrations, which happen Friday, we found a couple events around Philly that will be celebrating the spirit of the plant.
