I just wanted to and was only waiting for my first opportunity to come along. I can't say for sure when the desire first hit me, but every time I heard Bob Dylan's Rainy Day Women #12 & 35, I wanted to give it a try, and if I remember right, that came out in 1966, so it took me another two years before I had my chance.
The origin of the 4:20 smoke break is claimed to be:
According to Steven Hager, editor of High Times, 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. While our teens feel that they know something we don't, you can let them in on the fact that it was your generation that came up with the numbers.
A quote from one of the Waldos in the High Times article states, "We did discover we could talk about getting high in front of our parents without them knowing by using the phrase 420." Fortunately, your teenagers will not have that same option as their parents too grew up in a drug culture and should pretty much know better.
But I have wondered from time to time if it's true origin came from Bob Dylan's Rainy Day Women #12 & 35. If you multiply 12 times 35 the answer is ... 420. Coincidence? Maybe ... but maybe not.
