Somehow I doubt that majority of drug users are from healthy families with kids.
Anecdotally, I know (or knew if they died) several people from PhD programs adjacent to my own who were habitual users of heroin (or stuff branded as such). I have significant experience with it (originating with friends in academia!!!), and it is very nice, but it just so happens that I like pooping more than I like opioids, which apparently is a stroke of luck
I also saw about 12 different heroin addicts in the streets next to my home, but tbh they were a lot less loud, aggressive and/or obnoxious than the alcoholics.
Despair is not even in the picture. Too bad you paint it as a viable excuse for making yourself even more stupid than usual.
