Smug hipsters like to think they're doing heroin by living vicariously through their favorite androgynous hipster musicians who have lyrics about heroin. Oddly enough, they would never touch heroin because of the stigma, even though painkillers and heroin are both opiates and chemically very similar.
Hipster: "No way dude, I'm never gonna touch that stuff. Heroin isn't even like a painkiller hurr durr. And I'm not a hipster (lie)."
