I don't smoke, never have and never will. But those whiny bitches who think they have "a right to clean air" ought to get the fuck out of a pub and go hiking. You want clean air? Then stay the hell away from crowds. Retarded hippies are the worst goddamn scum.
No, the worst scum are those who think they have a right to bring their self-destructive habits into public. If you've got a bad habit, you're the one who should find an isolated spot(go hiking) and slowly kill yourself there, not the other way around.
