What is “420” Anyway?

The origin of the term “420” has multiple theories and potential origins, but its exact origin is not definitively known. Here are a few popular theories:
  1. The Waldos: One theory traces the origin of 420 back to a group of high school students in San Rafael, California, who called themselves “the Waldos.” In the early 1970s, the Waldos supposedly used the term “420” as a code to meet after school at 4:20 p.m. to search for a hidden cannabis crop. While they were unsuccessful in finding the crop, the term “420” became associated with cannabis use and eventually spread.
  2. Grateful Dead: Another theory connects the origin of 420 to the band Grateful Dead. It is suggested that “420” was originally a code used by Grateful Dead fans to identify each other or to coordinate cannabis-related activities at concerts and gatherings. The band’s influence and widespread following contributed to the spread of the term.
  3. Police Radio Code: Some believe that “420” originated from a police radio code used to denote cannabis-related offenses. However, there is little evidence to support this theory, and it is likely a misconception or urban legend.

It’s important to note that these theories are speculative, and the true origin of “420” remains uncertain. Over time, the term has gained cultural significance and is now associated with cannabis culture and counterculture movements. It has become a symbol for cannabis enthusiasts and is often used to refer to cannabis consumption or as a shorthand way of identifying with the cannabis community.
