In the late 1970s, I worked in a record store (selling new vinyl records), we had a display case at the register with many of these same products available (as well as pipes and bongs), it wasn't that unusual in the U.S. Even today, I suspect most smoke/vape shops have similar items, although powder cocaine does not seem as common today as it was back then.

I remember one device in particular, it was a small metal cylinder, shaped like an overgrown bullet, designed so that you could fill the main chamber with powder, screw the top on, then by rotating a smaller cylinder inside, deliver one snort into the upper chamber with an opening at the top for pressing against your nostril. It allowed you to snort almost using just one hand, with no chance of spillage. I'd still have one, but I gave it to a friend a long time ago.
