The "official time" to smoke it up...
The original story:
A small group of kids in high school used to meet up everyday after school at 4:20 and smoke on the hill. One day on April 20th, at 4:20 they were all like "'s 4:20, and 4/20- we should make this celebration official" the celebration spread and now 4/20 is an amazing day to get blazed thanks to a group of high school kids from norcal from the 70's's 4/20...let's get blazed

time of first acid trip
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

Originated in Toronto highschools back in the late 70s as being the "safe" time to spark up.
School gets out at 3:30pm, takes about 45 minutes for general student population and teachers to leave the premises; this gives you time to hang out for a bit and to roll a few fatties.
Fuck man!'s 4:20...spark'er up. Whattaya waitin' for?
