Back in my hippie days (before I grew up), almost all potheads also used tobacco. That was the 60's-70's. EVERY dope smoker I've known or met in the last fifteen years has been a rabid smoker-hater. You had to go outside their house to have a puff on the evil cigarette, but you could light up a joint anyplace in the house, anytime you wanted. Consequently, I've come to hate them just as much as they do me.
Yes, that's the way it is now.
