And who can forget the inhalants! I was never without my Vicks Inhaler (methamphetimine does wonders for a stuffy nose; and I think the photo above indicates recent use thereof). The classroom was a garden of scents, from Magic Marker to the Holy Grail of freshly run-off mimeographs. And dare I say that Airplane Glue and Dope (I'm not making this up) -- not huffed or puffed, but just enjoyed as a side-benefit of model airplane construction; which perhaps helps explain the popularity of that hobby in the fifties.
Veering away from actual consumption, I won't even retail what you got in the average 1950s Chemistry Set, but suffice it to say that between it and some items purchased from the local pharmacy I was able to make enough black powder to burn up much of my bedroom, and lucky enough not to have set it off in a tightly sealed package.
And all of this probably helps to explain the sixties and seventies.
