im not too sure...ive just always thought of it as something that connects all stoners, regardless of where it was derived, 420 is just one of those things...its here...its awesome...ENJOY IT...but in ottawa (canada's capital) you are allowed to on april 20th to smoke as much ganga as you want as long as you are not dealing and ON PARLIMENT (canadas white house) property, its awesome and you thought you've seen a "sea of green" lol dunno if that had nething to with the creation of 420 though.
as much as you think your story is right someone will always say different,
so according to me, we, us stoners created it, its a mutual bond
