“420” is a term that has become synonymous with marijuana culture and is celebrated every year on April 20th. But what exactly is 420, and how did it become so iconic? In this article, we will explore the history, cultural impact, and significance of 420, as well as how it continues to shape the cannabis industry and the legalization movement.

A Brief History of 420

The Waldos and the Origin of 420
The story of 420 dates back to the early 1970s in San Rafael, California. A group of high school friends, known as the Waldos, would meet at 4:20 PM after school to search for an abandoned cannabis crop rumored to be hidden nearby. They never found the crop but continued to use “420” as a code for marijuana. The term 420 slowly spread, becoming a worldwide phenomenon.

The Grateful Dead Connection
The Grateful Dead, a popular American rock band, played a significant role in spreading the term 420. The band members were friends with the Waldos and became aware of the 420 code. As they toured around the world, the Grateful Dead and their loyal fan base, the “Deadheads,” helped popularize 420 as a term associated with marijuana.
