You seem to be watching different anti-smoking commercials than I am. None of them have a "just say no" approach and all of them attack the "greed" of tobacco company executives.

I've seen those that you are talking about.

The "just say no" ads don't explicity say "just say no," they just feature one kid who, after having been talked to by a parent, is offered a, gasp!, cigarette by a friend. The kid turns to the friend and say "no," and the friend walks off. Then, the voice-over states "talk to your kids about not smoking."
