See its an interesting topic actually. IF we are talking about cigarettes, in the US you will tend to find it less common then in the EU or Japan. that is because in todays society we have been taught it is not good to smoke, and people actually frown upon you for doing it. I am not saying it is never done or rarely done but more then not it is not. I only say this from talking to a person who use to live in Washington then got drafted for the EU basketball team. He smokes and was telling me about this and the more I thought about it the more it made since. However this is more significant in chewing tabaco.
