420 (sometimes stylized as 4:20, Four-Twenty, etc.) is a code-term used primarily in North America that refers to the consumption of cannabis and is popular in cannabis subculture. Although many origin stories exist, the most widely discussed concerns the “4:20 Louis” group that searched for abandoned cannabis crop near San Rafael High School. April 20th has become a counterculture holiday in North America where people gather to celebrate and consume cannabis with each other.
