Every April 20th, cannabis lovers across the world light up, chill out, and celebrate a holiday that’s become a symbol of freedom, fun, and a whole lot of green . But how did 420 become the number, the code, the day? Like any good myth, the story of 420 is layered; part fact, part folklore, and fully embedded in counterculture history. At Cycling Frog, we’re all about honoring cannabis culture and exploring the deeper stories behind the vibes. So let’s cycle back through time, trace the roots of 420, and share how we’re celebrating the most iconic cannabis holiday of the year.
So… What Is 420, Really?
Before we get into the origin story, let’s clear the haze. There’s long been confusion about the origins of 420, leading to a fair share of urban legends. Some theorized it’s the police radio code for cannabis use (...it’s not). Others point to Bob Dylan’s “Rainy Day Women #12 & 35,” with it's famous line “Everybody must get stoned”, as well as 12 multiplied by 35 equaling 420. Cool math, but also, nope. While these rumors have added to the mystique, the real story behind 420 is much more interesting, and deeply tied to West Coast counterculture, secret codes, jam bands, and the power of community.

The Cultural Pre-History: Slang, Prohibition, Tea Pads & Juke Joints
Long before “420” was a thing, cannabis had its own secret language. During the jazz and blues era of the 1920s and ‘30s, terms like “gage,” “muggles,” “reefer,” and “viper” echoed through smoky clubs. Informal lounges known as “tea pads” popped up in cities like New York and Chicago, where people gathered to share music and marijuana. Cannabis culture thrived underground—despite rising moral panic from anti-marijuana propaganda films like Reefer Madness (1936), which painted cannabis as a gateway to insanity. These campaigns sparked decades of prohibition, making coded language an essential part of the culture’s survival.

The Waldos and the Birth of 420
Fast forward to 1971, San Rafael, California.
A group of high schoolers: Steve Capper, Dave Reddix, Jeffrey Noel, Larry Schwartz, and Mark Gravich, known as “The Waldos” (because they liked to hang out by a wall outside school) heard a rumor that would change history: A Coast Guard service member could no longer tend to a cannabis crop he’d planted near Point Reyes, and in the fall of ‘71, he offered up a hand-drawn map of its location to anyone willing to find it.
The Waldos were intrigued.
They made a plan to meet up after school — at 4:20 p.m., to be precise — near the statue of Louis Pasteur on campus. They’d light up and travel around, searching for the elusive weed grow. While the treasure hunt fizzled and they never found the crop, they did find something that stuck: “420”. The number was specific, and it had an almost secretive vibe, which made it all the more appealing for their group of friends. Soon, “420” became shorthand for their social gatherings and cannabis consumption.
But what started as a small, private code between a group of high school friends was just the beginning of something bigger.

From Code to Culture: The Grateful Dead & Grassroots Spread
Here’s where things get interesting. One of the Waldos’ fathers managed real estate for the Grateful Dead, and another had a brother who worked as a roadie for the band. This close connection to the Dead gave the Waldos an opening to introduce their code into the larger, more widespread counterculture of the band’s followers.
With the Dead’s tours already a focal point for a cannabis-loving, free-spirited community, “420” naturally found a place among Deadheads. The band's ethos of peace, freedom, and rebellion resonated deeply with the term, which encapsulated not just cannabis culture but a broader countercultural identity.
Through the Dead’s network, “420” spread like wildfire. Word of mouth among the band’s fans, stickers on cars, cassette tapes exchanged in parking lots, and flyers at shows all helped the term take root across the United States. The tight-knit, traveling community of Deadheads embraced "420" not just as a time to smoke but as a symbol of shared experience and resistance against mainstream norms. Long before the internet, this grassroots spread made “420” a national phenomenon, and eventually, an international one.
The real power of “420” came from this organic diffusion; it wasn’t something imposed by marketing or media, but something that grew from the ground up, driven by a collective culture that was as rebellious as it was laid-back.

High Times, Higher Profile
The next major milestone came courtesy of High Times magazine. In 1991, the publication mentioned the term "420" and offered their best guess at its origin, included on a Grateful Dead concert flyer: "It started as the police code for marijuana smoking in progress." Although the true origin was still largely unknown at the time, High Times repeated this explanation in several issues throughout the 1990s. Their consistent use of the term and the accompanying origin story played a major role in cementing 420’s place in cannabis culture. From there, the number became ubiquitous; on hats, hoodies, and headlines. It was no longer just a time of day; it was a date, an identity, and a declaration.
It wasn't until the Dec. 1998 issue of High Times, 27 years after the term was born, that the magazine decided to follow an email lead from Steve "Waldo", claiming that he and his friends where the originators of 420. That's when the pieces began to fall in place. The evidence provided by the Waldo's was irrefutable, and an article was published, finally amplifying the Waldos’ origin story and setting the record straight. With '420' already deeply intertwined with cannabis lore, popularizing the true origin has proved somewhat difficult, with many still unaware of it's true legacy.
From Underground to Mainstream: The Commercialization of 420
As legalization spread and cannabis culture moved into the spotlight, 420 transformed from a quiet code to a full-blown holiday. Cannabis brands (like us!) now celebrate with sales, limited-edition drops, and events. While some longtime enthusiasts may miss the underground days, the rise of 420 as a cultural and commercial moment reflects how far cannabis acceptance has come; and how many people now feel empowered to enjoy it openly. After all, the freedom to have safe and effective cannabis products delivered directly to your door is something worth celebrating!

Modern 420: Global Vibes, Local Roots
420 is now a worldwide celebration. From gatherings at Hippie Hill in San Francisco’s Golden Gate Park to marches in Toronto, parties in Berlin, and smoke sessions in Cape Town, the holiday is global. And it’s not just about consumption, it’s also about protest and progress. Many 4/20 events double as advocacy rallies, pushing for policy reform and cannabis justice.
Here in the Pacific Northwest, we’re proud of our roots. While it didn’t land on April 20, Seattle’s legendary Hempfest (RIP to our favorite protestival…) provided a platform for decades of activism that helped lead to legalization in our home state of Washington.
Why 420 Still Matters
At Cycling Frog, we honor the trailblazers; the Waldos, the Deadheads, the tea pad and juke joint jammers, the activists, all of the non-violent cannabis users who have been criminalized and jailed, and all the curious minds who fought for cannabis culture when it wasn’t yet accepted. It’s because of their persistence, creativity, and courage that we can now raise our cans with pride.
By drinking Cycling Frog, you’re not just enjoying a refreshing, reliable product; you’re giving a nod to the pioneers who paved the way for today’s cannabis culture, and embracing a future where safe, accessible, and consistent cannabis is available for all. Whether you’re watching a movie, jamming out, taking a walk, or splitting a 6-pack of Cycling Frog with friends, know that you’re part of a long, rich history and an exciting new chapter in the evolution of cannabis.
