I honestly, until this very day, always thought 420 was the police code for marijuana. Turns out there is a multitude of stories, legends and myths associated with the origin of 420. Time and Vox have both done articles about the origin and seem to conclude that the most likely credible story goes back to the 1970s. in 1971, a group of high schoolers from Marin County, California, would meet at 4:20 to smoke weed. This group, who called themselves the “Waldos”, because they met by a wall, would use 420 as a code for weed.
Later, one of the members of the Waldos, Dave Reddix, would become a roadie with The Grateful Dead. The band is said to have helped popularize the term. A group of “Deadheads” in 1990 handed out pamphlets asking people to smoke weed on April 20th at 4:20 pm. One of the pamphlets ended up in the hands of Steve Bloom. Steve Bloom, a former reporter for “High Times” would publish the pamphlet in 1991. And the term would continue to be used in the magazine from then on. Soon after the code became synonymous with weed worldwide.
While that is just one story of the possible origin there are plenty of others that range from plausible to questionable to outright bizarre. Here are some of the fun ones I’ve found. If you have any others you’ve heard, please message us on social media.
