Secondhand & Thirdhand Smoke
Secondhand smoke comes from burning or heating tobacco through a cigarette, cigar, pipe, hookah or electronic cigarette. It also comes from the air a smoker exhales while smoking. Electronic cigarettes also emit an aerosol that can be inhaled by bystanders.
Nonsmoking adults can suffer from health conditions such as heart disease, stroke and lung cancer if they are exposed to smoke. Consequences of secondhand smoke exposure for children is of great concern and a cause of respiratory problems, ear infections, asthma attacks and a greater risk of sudden infant death syndrome (SIDS). When you enter a space that someone has smoked in, even if they are not actively smoking you and your children are being exposed to thirdhand smoke.
