The Origins of 420: How a Secret Code Became Cannabis' Global Holiday
The shorthand is everywhere. The actual history is better than most people know.
Every April 20th, cannabis culture has its holiday. But before it was "420" you saw on t-shirts and stickers, it was a meeting time for a group of teenagers in northern California. Here's the real story.
1971, San Rafael, California
A group of five friends at San Rafael High School — who called themselves "the Waldos" because they hung out by a wall — heard about a cannabis plot hidden in the forest near Point Reyes. Its owner had supposedly abandoned it. The Waldos decided to look for it. They agreed to meet at 4:20 PM, after school, by a statue of Louis Pasteur.
They never found the plot. But they kept meeting at 4:20 — and "four-twenty" became their code word for cannabis. Short, ambiguous, and private — they could say it in front of parents and teachers without getting busted.
From San Rafael to the Grateful Dead
Several of the Waldos had connections to the Grateful Dead — one's older brother was close with the band, another ended up working for Dead bassist Phil Lesh. The band picked up the code and carried it on tour. Deadheads across the country adopted it. By the late 1980s, it was in zines; by the early 1990s, it was everywhere.
The urban legends
You'll still hear a lot of theories: that 420 is a police code for marijuana (it isn't), that it's the number of active chemicals in cannabis (not even close), that it's the date Bob Marley died (he died May 11, 1981). None of those are true. The Waldos story is the real one — and the original group has the postmarked letters and memorabilia to prove it.
420 in the legal era
Today 420 is a global event, with legal dispensaries in dozens of U.S. states and countries worldwide running specials, hosting events, and celebrating the culture that got us here. At NY Elite, we typically run our biggest specials of the year on April 20th — last year's lineup featured NY cultivator drops, live music on Bell Blvd, and door-crashing prices on flower and vapes. Follow our Specials page for this year's.
It's also worth remembering what the holiday originally represented: friendship, a sense of belonging, and a little rebellion. Cannabis is legal for adults in New York now, but the culture — the community, the stories, the codes — is still the reason people care.
