I'm a very happy non-smoker but I would think that the biggest reason for smokers to stop nowadays is the leper colony stigma aspect. I would think that smokers (rightfully) feel like a shunned minority when they are told to smoke in alleys far away from the general population. They have to make a special effort to go somewhere to smoke because they can no longer light up at a restaurant or while they're doing errands. It's hard to pretend you're "cool" when you're standing by yourself and society doesn't want you anywhere near them. So there's no coolness and no convenience.
