That old saying, if you smoke, your family smokes, is true. Children exposed to smoker's smoke have increased risk of lung infections, such as asthma, bronchitis, and allergies and ear infections, as well. There are two types of smoke coming to a nonsmoker the mainstream smoke, which is the smoke inhaled and exhaled from the smoker. Then there is the sidestream smoke which is the smoke from a cigar or cigarette just burning in an ashtray. The sidestream smoke has even more carcinogens it is giving off into the air.
Smoke also contains tar, nicotine and carbon monoxide.
Second hand smoke inhalation causes increased risk of lung infections and lung diseases such as pneumonia, bronchitis, asthma, emphysema, cancer, as well as, ear infections, sinus problems, heart disease, strokes, nose, eye and throat irritation, nausea, dizziness and headache. Not to mention stains on clothes and material and a very unpleasant smell that gets onto to your body and into your hair and clothes. There is sufficient documented studies on the dangers of second hand smoke. Also called passive smoking, non-smokers who breathe second hand smoke from smokers have an increased chance of developing lung cancer. Tobacco specific carcinogens have been found in the blood and urine of nonsmokers who were exposed to environmental tobacco smoke.
