3. Tobacco • Nicotine: a substance that causes physiological or psychological dependence • All tobacco products contain nicotine • Nicotine is classified as a stimulant, which is a drug that increases the action of the central nervous system • Nicotine raises blood pressure, increases heart rate, and contributes to heart disease and stroke

4. Toxic Mixture • Tobacco smoke has been classified as a Group A carcinogen. A carcinogen is a cancer-causing substance • Cigarettes contain tar, tar penetrates the smoker’s respiratory system and destroys cilia. Cilia is the tiny hair-like structures that line the upper airways and protect against infection by regulating mucous. (This is why smokers have to cough or hack in order to move mucous out of the lungs) • Carbon monoxide is also found in cigarettes, it replaces oxygen in the blood, thereby depriving the tissues and cells of oxygen.

6. Effects of Smokeless Tobacco • It’s tobacco that is sniffed or chewed • This is not a safe alternative to smoking • Since smokeless tobacco is often held in the mouth for a long period of time, it delivers both nicotine and carcinogens to the body at levels that can be two or three times the amount delivered by a single cigarette • Leukoplakia is a result of smokeless tobacco. It is thickened, white, leathery-looking spots on the insides of the mouth that can develop into oral cancer.

8. Chronic Bronchitis (Cilia no longer functions) Lung Cancer (Cancerous cells grow as a result of mucous not being regulated) Stroke (Arteries become clogged, increasing the risk of heart attack and stroke) Emphysema (Air sacs in lungs are destroyed, much more difficult to absorb oxygen) Coronary Heart Disease (Constrictions of blood flow to the heart) Long-Term Affects of the Body

15. Effects of smoke on Unborn Children • Smoking during pregnancy can seriously harm the developing fetus • Nicotine passes through the placenta, constricting the blood vessels of the fetus • Carbon monoxide reduces the oxygen levels in the mother’s and the fetus’s blood • These negative effects increase the risk of impaired fetal growth, miscarriage, prenatal death, premature delivery, low birth weight, deformities, and stillbirths • Babies can also suffer from growth and developmental problems throughout early childhood

16. Effects of smoke on Infants • Children of smokers are nearly twice as likely to be in poor health as those of nonsmokers • Children of smokers tend to have a higher incidence of sore throats, ear infections, and upper respiratory problems • Children who live with smokers have double the risk of developing lung cancer • Because children learn by example, it’s not surprising that children of smokers are nearly three times as likely to smoke as children of nonsmokers (Being a positive role model is another good reason to make the choice to be tobacco free)
