It's both more and less than people make it out to be. '420' began its sub-rosa linguistic career in 1971 as a bit of slang casually used by a group of high school kids at San Rafael High School in California. '420' (always pronounced "four-twenty," never "four hundred and twenty") came to be an accepted part of the argot within that group of about a dozen pot smokers, beginning as a reminder of the time they planned to meet to light up, 4:20 p.m. Keep in mind this wasn't a general call to all dope smokers everywhere to toke up at twenty past four every day; it was twelve kids who'd made a date to meet near a certain statue. It's thus incorrect to deem that '420' originated as a national or international dope-smoking time, even though the term began as a reference to a particular time of day.
