Used to be this inhaler, the Benzedrex nasal inhaler, that was over-the-counter. It contained, among other things, racemic amphetamine free base. So instead of inhaling it, you’d make a foul tea with it and get wired, very very wired. There is a jazz tune, Who Put the Benzedrine in Mrs Murphy’s Ovaltine? When amphetamine went on the Controlled Substance Act Class 1 list, they switched to propylhexedrine.
Then there’s Asthmador, you were supposed to smoke these Asthmador cigarettes to stop wheezing. They contained belladonna leaves (or maybe Jimson weed), and if you made a tea, you could get a dissociative, hallucinatory high for a day or so.
People will seek out these experiences, they have for thousands of years. lol There are probably an equal number of people shrieking BAN IT! since Thag the Caveman ate some strange mushrooms.
One of my sisters inhaled Asthmador when she was young. Perhaps side effects far longer than a day or two (she forgot she promsed to repay me a $$$$ loan... and asked me when she ever said THAT..... )
