I don't have an issue with banning the smell of cigarettes. If someone is being rushed in, hurt, they may not have the time to put on a mask or whatever and if the smell were to somehow cause a peron to have breathing issues then it could make the difference between someone making it or not. My dad smokes, smoked my whole life and I almost never ended up smelling like smoke. All you have to do to avoid the smell sticking to others who live with you is not smoke in the house or in the car. And while it's harder to keep the smell off yourself if you're the smoker, there are ways to keep it way down. AND there are those new smokeless cigarettes. So people could still keep the habit if they don't want to quit.
