LSD, MDMA hadn’t even been invented.
Pot smoking was little known outside certain subcultures.
Cocaine was known and abused as were opiates via smoking (rare) or in patent medicines which was common and that’s what I figure you are referring to.
Remember that song Wooly-booly? About Hadacol Haddie?
I call BS to your BS. For the same reason: Not much.
Pot was a well known weed and this nation didn’t turn into a bunch of pot heads, no more than we are all a bunch of drunks because we legalized alcohol.
The same arguments were made of medicinal pot: “Look out! Colorado will turn into a State full of potheads! OH, MY GOD!!!!”
Sorry, didn’t happen. In fact, 99% of the country probably didn’t even know we had legal pot.
