'Pot day,' 'weed day,' or simply '420': Call April 20, the day hippies and other marijuana enthusiasts come together to celebrate all things cannabis, whatever you like. Most stories of its origin are apocryphal, including the legend that '420' was California police code for a marijuana bust. But according to the Huffington
... Post, the holiday stems from a group of California teenagers in the early '70s who met at 4:20 p.m. to smoke marijuana after class. With the help of Grateful Dead fandom, the term spread through the hippie subculture and was later launched into a full-on buzzword when it was adopted by High Times magazine. Who among those after-school stoners would have guessed that their bit of teenage slang would now serve as the inspiration for the celebration of pot?
