I would guess because getting drunk used to be called "getting stoned" so they also started callin' the high from weed "stoned", and a person who gets "stoned all of the time is a "Stoner" just a a person who cleans is a cleaner, or a person who paints is a painter. Does anybody know what I mean?
Maybe because when people are high they look like a stone not doing anything which is where "stoned" prob came from then that brought about stoners idk
Reviving this thread because I just thought of this question. Stoner is such a stoner word too. "Dude how do you feel?" "Like....stone." *Both face each other in excitement and scream in unison "WE'RE STONERS! "
i think he ment like just the general word " stone" like cuz we act like stone/rocks when we're high haha idk
