Smokers aren't usually bothered by the smell of smoke that lingers in their hair and clothes. However, after they quit, they often find that instead of making them want to smoke, that smell offends them the way it does most other non-smokers. After quitting, getting rid of that unpleasant smell is usually as easy as brushing your teeth, taking a shower and making a trip to the dry cleaner. Yellow stains will start to fade from your teeth with time, as well. If you made a habit of smoking in the house or car, have your carpets and upholstery professionally cleaned to get rid of any lingering odor. It might take a while for the odors to completely diminish, but you won't be the only one to notice you don't smell like an ashtray anymore.
