Cannabis Culture

Few numbers are as instantly recognizable in cannabis culture as 420. Whether whispered among friends, displayed on social media, or celebrated in large public gatherings, 4/20 has become synonymous with cannabis advocacy, consumption, and community. But where did it all start? While many myths and urban legends surround its origins, the truth behind 4/20 is both fascinating and deeply rooted in cannabis history. Let’s explore how this once-secret code grew into a worldwide phenomenon.

A Timeline of 4/20’s History

The history of 4/20 spans decades, evolving from a local phrase among high school friends into a worldwide cannabis movement. Below is a timeline showcasing key moments in the rise of 4/20:

1971: A group of high school students in San Rafael, California, known as “The Waldos,” began using “420” as a code for smoking cannabis.
Early 1990s: The term spread through the Grateful Dead community, gaining traction among cannabis enthusiasts.
1998: High Times magazine popularized 4/20 as the official cannabis holiday.
2010s-Present: April 20th (4/20) became a mainstream celebration with large-scale events, legalization rallies, and dispensary deals worldwide.

What Is 4/20 and What Does It Mean?

4/20 has become more than just a number; it represents an entire subculture. Originally a codeword for smoking cannabis, it has grown into a global holiday where cannabis consumers and advocates unite to celebrate and push for legalization and reform. Whether it’s a time of day (4:20 PM) or a date (April 20th), the term is synonymous with cannabis appreciation.

The Origin of 4/20: Fact vs. Myth

While many stories exist about the true origin of 4/20, the most widely accepted account traces back to a group of five California high school students, known as “The Waldos.” They would meet at 4:20 PM after school to search for a rumored abandoned cannabis crop.

Though they never found the crop and, instead, “420” became their shorthand for smoking weed. As the phrase spread through the Grateful Dead community, it was eventually popularized by High Times magazine in the late 1990s, securing its place in cannabis culture.

Myths and Misconceptions About 4/20

Now, over the years, several myths have circulated about the meaning of 4/20, with some theories becoming so widespread that they are mistaken for fact. Here are some of the most common misconceptions:

“420 is a police code for marijuana.” Many people assume 420 was a police radio code for cannabis-related offenses, but according to Verify, no known law enforcement agency has ever used “420” in this way.
“420 comes from a Bob Dylan song.” Some claim that “Rainy Day Women #12 & 35” (since 12 × 35 = 420) inspired the term, but reports claim there is no evidence supporting this connection.
“April 20th is the best time to plant cannabis.” While spring is a common planting season for cannabis, 4/20’s origins have nothing to do with agriculture.
“420 originated from a government conspiracy.” Some believe the government created 4/20 to track cannabis users, but this is pure fiction.
