You could avoid visiting places where smokers visit. You can ask your friends to not smoke around you and avoid going to any smokers' homes. If you are extremely concerned, you could buy and wear medical masks. However, non-smokers must also realize that they are surrounded by unseen air particles every day that can cause lung irritation or lung damage; air pollution in most cities and on highways is far more prevalent than second-hand smoke. As well, the only type of "mask" that truly reduces the irritants in the environment are what's known as a "rebreather mask" that cost anywhere from $2.00-4.00 EACH (compared to twenty-fifty cents for a "cone mask" or "surgical mask" which do not filter out small particles or smoke).
