You could advertise anything in the 1970s.
When cocaine was king, there was suddenly a market of "required" accessories, along with advertising for every last type of tool you might need to keep your supply fresh and put it up your nose. It's hard to believe there was a time when you couldn't order senseless junk from the Internet while you were in a different state of mind. Back in the day, you had to send away for that stuff from the back of magazines. Just so you could be the flashy one at the party.
