you guys are fucking stupid, 420 was originated in southern california by a group called the waldos, 1 of them heard about a patch of weed plants so they decided to go look for it after school at 4:20pm they never found the weed patch but they still got high as shit off the stuff they did have. Today it is national weed smoking day/time and is today, so im still a little high =D

The 20th day of April, or National Potsmoking Day in the US. Who cares where the number 420 originated, just go out and some some pot for pot's sake.

Pothead#2: "I'm going to smoke weed all day!"

The number silly, little teenagers talk about for days upon days, but do not get high when April twentieth is finally here.

April twentieth is also Adolf Hitler's birthday. This day is not commonly known as "420" when referred to Hitler's birthday, though.

There is belief that "420" is the police code for a "drug bust," but it is not. There are no codes for a "drug bust," only "drug deal," which is code "966."
