In the crime/drama movie Drugstore Cowboy, after returning to his hometown, Bob talks to a drug counselor lady:
Lady: Have you ever considered becoming a counselor and helping other addicts with their problems?
Lady: Why not?
Bob: Well, to begin with, nobody and I mean nobody can talk a junkie out of using. You can talk to them for years, but sooner or later they'll get a hold of something. Maybe it's not dope. Maybe it's booze. Maybe it's glue. Maybe it's gasoline. Maybe it's a gunshot in the head. But something. Something to relieve the pressures of their everyday life, like... having to tie their shoes.
