Why "420" Became Weed's Magic Number The term "420" is deeply embedded in cannabis culture, signaling time to light up or celebrate marijuana on April 20 (4/20). Its origins trace back to a simple high school ritual in 1970s California that snowballed into a global phenomenon.

The Waldo Origin Story

In 1971, five students at San Rafael High School in Marin County—Steve Capper, Dave Reddix, Jeffrey Noel, Larry Schwartz, and Mark Gravich—dubbed themselves the "Waldos" for meeting by a campus wall. After extracurriculars, they'd rendezvous at 4:20 p.m. to hunt for rumored cannabis plants and smoke, using "420" as discreet code.

Dave Reddix later roadied for the Grateful Dead, spreading the term among Deadheads. A 1990 flyer from Oakland urged gathering on April 20 at 4:20 p.m., which High Times magazine amplified in 1991, rocketing "420" nationwide.

"They wanted people all over the world to get together on one day each year and collectively smoke pot at the same time." – Steve Bloom on the flyer's impact

Busting Popular Myths

  • Police code? No—California's HP 420 was for "station in vicinity," not weed.
  • Chemical count? Cannabis has over 400 compounds; 420 isn't the "high-inducing" total.
  • Bob Marley tie-in? His birthday was February 6; the Dylan song math (12x35=420) is coincidental fun.

These tales persist in forums like Reddit's r/OutOfTheLoop, where users debate endlessly, but Waldos' evidence (flyers, tapes) holds up.

How 4/20 Evolved into a Holiday

From stoner meetups, 4/20 grew via Grateful Dead tours and High Times into mass events—think Golden Gate Park gatherings or dispensary sales bonanzas. By the 2010s, legalization waves (starting California 1996) made it commercial: deals at Wingstop? Snoop Dogg THC drinks? All 4/20 staples.
