There was no canned air back then

Yes there was, but it was expensive, and not many stores around carried them since they were mainly used for keyboards. The early cans had Freon in the cans. Then people started getting high off the cans when they stopped putting Freon. That is when they started putting a bittering agent to get people to stop huffing the compressed air.
