40 years ago it was Pam cooking spray
And a little before that, it was Right Guard Deoderant.
Sharpies.
I remember a fellow touting the great high from huffing gasoline. Just pull the cap off and stick your nose in the filler hole. Really cheap high! An old friend worked in the fiberglass boat factories in St Petersburg in the 70s and smoked a lot of dope, too. Last time I saw him he was a highly payed detail specialist but could not put a three word sentence together. He was picked up at his house by a company driver in the AM and taken to the appropriate dock to do the final detail work then taken home at the end of the work day. Lots of guys scrambled their brains working in the boat factories.
