Provide evidence for your claim.
How would you like your evidence: from the literature or anecdotal?
In my reading on drug use, the 60's are widely acknowledged as a time of expanding drug acceptance. Pot was not popular among a wide audience until the 60's youth seized onto it as part of the Revolution. Prior to that, the artist/poet/grifter/drifter set knew all 'bout it, more likely in the form of hashish.
In my experience with it personally—I was born in '62—my parents reported that in their generation alcohol was the glamour drug, with harder substances still only used by "bad" folks. Pot was not popular among their generation.
It was popular enough among mine that I eventually tried it and after off-and-on attempts at it I found out I liked it...enough to become a bit of a pothead for awhile.
