Just so everybody is clear this is how 4/20 actually started.

4:20 was the time of day some stoners at San Rafael High in Northern California (represent) would get together every day after school to smoke weed and get high. It is now a huge part of our culture, basically the word for the "weed culture."

It's also a holiday, April 20th, (coming up!) and the only place to be at 4:20 on 4/20 is Hippie Hill in San Francisco.
hey dude look, it's 4:20, take a hit!

shit, what are you doing on 4/20? GETTING HIGH OF COURSE

April 20th; A day where actual cannabis-smokers do the ganja. Also the day where a bunch of poseurs claim that they're gonna smoke weed on that day to try to be cool, but really don't.
So, I don't do marijuana on 4/20. Fuckin' sue me.

a TIME in the 70's where a group of teens would gather after school got out to smoke marijuana. 4:20 was the perfect time because it was after school, enough time to get the weed and smoke before parents got home. since then april 20th has become a "holiday" in which people celebrate smoking marijuana! also, 420 is NOT a police number and they do NOT say that when they see people doing drugs.
"you wana get high? afterall it is 4/20."

"happy holidays, its 4/20"
