hipsters
After reading the whole poem, I wanted to know what drugs the people described in the poem were taking so I did some 1950s drug research and I came across this: https://www.pbs.org/wgbh/pages/frontline/shows/drugs/buyers/socialhistory.html If you scroll down a bit, there is a section about opium and herion, and these users are specifically called "hipsters". I didn't know that, I assumed when it said hipsters it was like today's version of a hipster, you know, someone who carries around a typewriter for the aesthetic and was into that band you like waaaay before you even knew about them. But it's not that, it's a term referencing members of the "Beatnik" aesthetic who abuse heroin. It kind of makes the poem make a lot more sense, knowing that.
