The Origins of 420: Waldos and Treasure Maps

Contrary to popular belief, 420 doesn’t refer to a police code or the number of active chemicals in cannabis. The real history of 420 begins in 1971 with a group of high school students from San Rafael, California. These teenagers called themselves “the Waldos” because they liked to hang out by a wall outside their school.

The Waldos had heard about an abandoned cannabis crop near the Point Reyes Coast Guard Station. They planned to meet at 4:20 PM after school activities to search for this hidden treasure. They would remind each other in the hallways by simply saying “420,” which became their code for smoking cannabis.

Though they never found the legendary crop, their code stuck. Meeting at “4:20” to smoke became their regular routine. This simple time reference might have remained just another piece of forgotten teenage slang if not for an incredible stroke of luck.

The Grateful Dead Connection

One of the Waldos had connections to the Grateful Dead through his father, who managed real estate for the band. The Waldos frequently hung around the band’s practice sessions and backstage areas, where their “420” code began to spread among the band members and their fans.

As Deadheads traveled across the country following tours, they carried this bit of slang with them, spreading it throughout cannabis culture across the United States during the 1970s and 1980s.

How 420 Evolved: From Secret Code to Cultural Icon

The history of 420 took a significant turn in the early 1990s when High Times magazine discovered and published the term. In 1991, a reporter spotted a flyer at a Grateful Dead concert that invited people to “meet at 4:20 on 4/20 for 420-ing.”

Intrigued, High Times printed the flyer and began using the term regularly. With each mention, “420” gained more recognition among cannabis enthusiasts. By the mid-1990s, April 20th had begun transforming into an unofficial holiday, with small gatherings and celebrations taking place across North America.

From Underground to Mainstream

What started as a secret code gradually entered the public consciousness. The late 1990s and early 2000s saw 420 references pop up in movies, music, and even clock scenes (filmmakers often set clocks to 4:20 as an inside joke).

As cannabis advocacy grew and legalization movements gained momentum in the 2000s and 2010s, 420 celebrations became larger and more public. Annual gatherings in places like Denver’s Civic Center Park, Vancouver’s Sunset Beach, and universities across North America drew thousands of participants.

Common Myths and Misconceptions About 420

The history of 420 is clouded with myths that continue to circulate. Let’s clear up some common misconceptions:

• Police Code Myth: Many believe 420 is the police radio code for marijuana possession. It’s not – most police departments don’t even use this number for cannabis-related incidents.
• Bob Marley Myth: Bob Marley died on May 11, not April 20, and has no direct connection to the origin of 420.
• Chemical Compound Myth: Cannabis doesn’t contain exactly 420 chemical compounds (it actually has over 500).
• Hitler’s Birthday Myth: While Hitler was indeed born on April 20, this coincidence has nothing to do with why cannabis enthusiasts chose the date.

How 420 Is Celebrated Today

Today, 420 serves as an international day of cannabis celebration, education, and advocacy. From small private gatherings to massive public events with tens of thousands of attendees, April 20th has become a day for the cannabis community to come together.

These celebrations often include:

Have you ever attended a 420 celebration? They range from casual meet-ups to organized festivals with music, food, and educational components about cannabis culture and policy.

420 in Canada: Saskatchewan and Beyond

Since Canada legalized recreational cannabis in 2018, 420 celebrations have evolved from protest movements to more mainstream events. Here at REALEAF Cannabis Dispensary in Saskatchewan, we’ve watched the transformation of 420 from a counterculture moment to a more accepted celebration.

Saskatchewan’s 420 gatherings have grown over the years, with events in Regina, Saskatoon, North Battleford, and Prince Albert drawing cannabis enthusiasts from across the province. The history of 420 continues to develop as Canada embraces legal cannabis and builds new traditions around this once-secret code.

As legalization spreads globally, 420 is becoming less of a protest day and more of a cultural celebration. It’s fascinating to watch how this simple code created by a group of California teenagers has transformed into an international phenomenon that unites millions of people worldwide.
