There's lots of theories out there but the most commonly accepted one is this:
from urbandictionary.com
the term 420 originated at San Rafael High School, in 1971, among a group of about a dozen pot-smoking wiseacres who called themselves the Waldos, who are now pushing 50. The term was shorthand for the time of day the group would meet, at the campus statue of Louis Pasteur, to smoke pot. Intent on developing their own discreet language, they made 420 code for a time to get high, and its use spread among members of an entire generation.
Some people believe 420 is some police code for marijuana possession but I believe that one's been disproved.
There's a few others as well, some say it has something to do with a bible verse, and I believe some studies found that 4:20 PM is the most likely time for the average potsmoker to smoke. It makes sense, especially if you think about how high school ends somewhere between 3 and 3:30, go home, grab some food, meet up with your friends and you're sparking it right around 4:20.
