where does the term 4 20 come from
In 1971, five high school students -- Steve Capper, Dave Reddix, Jeffrey Noel, Larry Schwartz, and Mark Gravich -- in San Rafael, California, calling themselves the Waldos because "their chosen hang-out spot was a wall outside the school", used the term in connection with a 1971 plan to search for an abandoned cannabis crop that they had learned about, based on a treasure map made by the grower. The Waldos designated the Louis Pasteur statue on the grounds of San Rafael High School as their meeting place, and 4: 20 p.m. as their meeting time. The Waldos referred to this plan with the phrase "4: 20 Louis". After several failed attempts to find the crop, the group eventually shortened their phrase to simply "4: 20", which ultimately evolved into a codeword that the teens used to mean consuming cannabis.
