I can only speak from personal experience, which is of course limited. I smoked occasionally in my 20s, but not since (I'm middle-aged now). I've been friends and acquaintances with many people that smoke a lot. I see a trend among these people - not necessarily schizophrenia (I'm not a psychologist and probably wouldn't even notice a mild case) - but instead a consistent arrogance and self-importance. It's peculiar…
Would you rather have people demoralized and hating themselves? I think we have quite enough of that already. God forbid an unaccomplished waggie enjoys life and likes who they are. Somebody put these uppity proles back in their place!
