If you live with a smoker, ask him or her not to smoke inside your home. Discuss how his or her habit puts you at risk. If your partner is unwilling to go outside, suggest ways to limit the exposure of smoke for you. Maybe a room could be set aside for smoking—one that is seldom used by other members of the household. Some smokers protect others at home by smoking near an open window or when no one is around. It also helps to keep rooms well-ventilated and open windows.
