4:20 or 4/20 (pronounced four-twenty) is a term used in North America to refer to the consumption of cannabis and, by extension, a way to identify oneself with the drug subculture around cannabis.

On 20 April 2007 at 4:20pm PDT, over 700 people gathered at City Hall in Victoria, BC to celebrate Victoria's 10th annual 4/20 celebration. Victoria police were not visibly in attendance

420 is common in cannabis culture. As April 20th is 4/20 it is the cannabis national holiday. Festivities abound about North America. One of the largest gathering is at the Boulder campus of Colorado University. In 2007 over 6,000 people were in high spirits.

Origins and Observances[]

Although there are many explanations for the origin of the term, one stems from a story about a group of teenagers at San Rafael High School in San Rafael, California in 1971. The teens would meet after school at 4:20 p.m. to smoke marijuana at the Louis Pasteur statue. The term became part of their group's salute, "420 Louis!",and became popularized in the late 1980s by fans of the Grateful Dead. By extension April 20 ("4/20" in U.S. date notation) has evolved into a counterculture holiday, where people gather to celebrate and consume cannabis. In some locations this celebration coincides with Earth Week. In Dunedin, New Zealand, students at the University of Otago and other cannabis law reform activists meet under a walnut tree on the Otago University Union Lawn on Wednesdays and Fridays at 4:20pm to openly smoke cannabis in public in what they call an 'act of protest'.
