San Rafael, California San Rafael ( ; Spanish for " St. Raphael", ) is a city and the county seat of Marin County, California, United States. The city is located in the North Bay region of the San Francisco Bay Area. As of the 2020 U.S. census, the city's populatio ...

made by the grower. Calling themselves the Waldos, because their typical hang-out spot "was a wall outside the school", the five students—Steve Capper, Dave Reddix, Jeffrey Noel, Larry Schwartz, and Mark Gravich—designated the Louis Pasteur statue on the grounds of San Rafael High School as their meeting place, and 4:20 pm 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 "4:20", which ultimately evolved into a code-word the teens used to refer to consuming cannabis. Steven Hager of ''

'' popularized the story of the Waldos. The first ''High Times'' mention of 4:20 smoking and a 4/20 holiday appeared in May 1991 and erroneously attributed the origin of the term to a police code; this and other spurious incorrect origin stories became common. The connection to the Waldos appeared in December 1998. Hager attributed the early spread of the phrase to Grateful Dead followers—after "Waldo" Reddix became a

holiday based on the celebration and consumption of cannabis. Events typically advocate for cannabis liberalization and legalization. Vivian McPeak, a founder of Seattle's Hempfest states that 4/20 is "half celebration and half call to action". Paul Birch calls it a global movement and suggests that one cannot stop events like these. Many marijuana users protest in civil disobedience by gathering in public to smoke at 4:20 pm. As marijuana continues to be decriminalized and legalized around the world, cannabis activist Steve DeAngelo notes that "even if our activist work were complete, 420 morphs from a statement of conscience to a celebration of acceptance, a celebration of victory, a celebration of our amazing connection with this plant" which "will always be worthy of celebration".
