funny enough 4:20 is a lot more than a day for smoking weed. On April 19th 1943 at exactly 4:20pm, after many scientific experiments and tests, Dr. Alfred Hofmann took lsd-25 and was the first person to experience an acid trip

the best time to smoke. it started when led zeppelin was popular, because they would have concerts at 4:30 so people would start lighting up at 4:20 and keep on smoking through the concert.

All those stories about beaners starting it up in the 70's or whatever is not true.

It is really the anniversary of The Columbine High Shooting in 4/20/99
The two kids that shot up the school were both Neo-Nazis and decided to do it on Adolf Hitler's Birthday, Which is 4/20

Then some kid thought it would be cool to make it weed day or whatever.
its also Carmen Electra's Birthday.
"Those kids were smokin at 4:20 in the afternoon."

National Pot smoking day also known as Adolf Hitler's Birthday.

A day that everyone smokes as much weed as they possibly can............in order to keep Adolf Hitler in the Afterlife....forever......thus if you smoke pot.....you are against the Nazi's.
Happy 4/20
