Contrary to popular belief, the true genesis of 420 can be attributed to a group of high school students from San Rafael, California, in the early 1970s.

The Impact of the Grateful Dead

While the San Rafael students may have originated the term, the association between 420 and the Grateful Dead undoubtedly contributed to its spread beyond their immediate circle.
