In the world of cannabis culture, few symbols are as universally recognized as “420.” Whether you’re a seasoned enthusiast or just beginning to explore the world of cannabis, 420 represents more than just a number. It’s a cultural movement, a call for advocacy, and a global celebration held each year on April 20th.

So, how did this three-digit number become a symbol for an entire subculture? The history of 420 is filled with friendships, myths, music, and the unwavering spirit of counterculture that has propelled cannabis to the forefront of social change.

The Meaning of 420: More Than Just a Number 

At its core, “420” is a symbol of cannabis culture and the vibrant community surrounding it. What started as a secret code among a group of friends has grown into a powerful expression of identity, unity, and advocacy. Whether it’s lighting up at 4:20 PM or gathering on April 20th, 420 is a shared celebration of cannabis, a plant that connects people from all walks of life.

But it’s not just about smoking—it’s about the values of education, unity, and the push for cannabis legalization. 420 has become a rallying cry for those who believe in the benefits of cannabis and its rightful place in our society.

The Early Days: The Waldos’ Secret Code

The true origins of 420 lie in the early 1970s at San Rafael High School in Marin County, California. A group of five friends—Steve Capper, Dave Reddix, Jeffrey Noel, Larry Schwartz, and Mark Gravich—would meet regularly at 4:20 PM to search for a rumored cannabis crop left abandoned in the nearby woods. Armed with a treasure map and a shared sense of adventure, the group, later known as “The Waldos,” set out in hopes of finding their cannabis jackpot.

While the crop remained elusive, the term “420” became their code word for anything cannabis-related. It was a discreet way to plan sessions or discuss marijuana without raising suspicion among peers, teachers, or parents. The phrase quickly became an integral part of the Waldos’ slang, but its journey to international fame was only beginning.

What Does “420 Friendly” Really Mean?

You’ve likely seen the phrase “420 friendly” in dating profiles, social media posts, or even on business advertisements. But what does it really mean? Simply put, it signals acceptance and openness toward cannabis use, creating spaces where marijuana enthusiasts feel welcome and supported.

For example:

  • In Housing Ads: A “420 friendly” landlord or roommate is open to cannabis use in their space.
  • In Dating Profiles: The term signals that an individual enjoys or is comfortable with cannabis use.
  • In Businesses: Dispensaries, venues, and events may use “420 friendly” to communicate a cannabis-friendly environment.

It’s more than just a phrase—“420 friendly” is about creating connections and celebrating a lifestyle centered around cannabis culture.

420 Origins History

The Grateful Dead Connection: How 420 Went Mainstream

The Waldos’ connection to the Grateful Dead was the catalyst that propelled 420 from a local inside joke to a nationwide phenomenon. One of the Waldos, Dave Reddix, had a brother who managed a Grateful Dead side project, and Reddix himself worked closely with the band. Through these connections, the Waldos shared their code word with the Dead’s entourage.

As the Grateful Dead toured across the country, their devoted fanbase—known as Deadheads—began to adopt the term. The band’s culture of openness and community spirit allowed 420 to spread organically among fans, creating a shared language that resonated with cannabis enthusiasts everywhere.

420’s Rise to Prominence: High Times and Beyond

The definitive moment for 420’s rise to prominence came in the 1990s, when the term was amplified by High Times, a leading publication in cannabis culture. Steven Hager, then-editor of High Times, embraced 420 as a unifying symbol for cannabis users. The magazine popularized the number through articles, event promotions, and editorials, cementing its place in the lexicon of cannabis advocacy.

In 1998, High Times even interviewed the Waldos, officially crediting them as the originators of 420. This acknowledgment further solidified the term’s place in cannabis history and elevated the Waldos from local legends to cultural icons.
