Definitions • A cancer-causing substance. • The addictive drug found in tobacco leaves. • A colorless, odorless, and poisonous gas. • A substance that causes physiological or psychological dependence. • Thickened, white, leathery spots on the inside of the mouth that can develop into oral cancer.
Health Risks of Tobacco Smoke • Environmental tobacco smoke (ETS)- or secondhand smoke, is air that has been contaminated by tobacco smoke. • ETS is composed of mainstream smoke, the smoke exhaled from the lungs of a smoker. • Sidestream smoke is the smoke from the burning end of a cigarette, pipe, or cigar.
Health Risks of Tobacco Smoke • Since mainstream smoke has been exhaled by a smoker, it contains lower concentrations of carcinogens, nicotine, and tar. • Sidestream smoke is more dangerous than mainstream smoke. • ETS from cigarettes, pipes, and cigars contain more than 4,000 chemicals. • Studies have shown that infants and young children who are exposed to ETS are more likely to develop asthma than their peers who are not exposed to ETS.
Nonsmokers Young Children • Secondhand smoke causes about 3,000 deaths from lung cancer every year. • ETS causes eye irritation, headaches, ear infections, and coughing in people of all ages. • Increases the risk of heart disease. • Children of smokers tend to have a higher incidence of sore throats, ear infections, and upper respiratory problems than children of nonsmokers. • Secondhand smoke can slow lung development. Children who live with smokers are more likely to have weaker lungs than children of nonsmokers. Health Risks
Three Actions That Have Aided Efforts to Curb Smoking in Public Places • Laws that prohibit the sale of tobacco to minors (18) are being strictly enforced. • Some states have successfully sued tobacco companies to recover the costs of treating tobacco-related diseases. • Community activities that promote a healthy lifestyle provide everyone with the opportunity to practice healthful behaviors.

Nicotine and the Body Stimulants are drugs that increase the activity of the nervous system. Once in the blood, nicotine reaches the brain within seconds. By mimicking neurotransmitters, nicotine affects breathing, movement, learning, memory, mood, and appetite. The major short-term effects of nicotine use are increased heart rate, increased blood pressure, and changes in the brain that may lead to addiction.
Nicotine Addiction Ongoing use of nicotine causes the body to develop a tolerance to nicotine. As tolerance increases, nicotine addiction develops. The time it takes to become addicted depends on several factors including genetics, frequency of use, and age. Studies show that teens become addicted faster and more intensely than adults. Psychological Dependence Tobacco use may become a habit used to cope with stressful situations. It may become associated with social situations.

Health Risks to Unborn Children and Infants • 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 blood of the mother and fetus. • This increases the risk of impaired fetal growth, spontaneous miscarriage and prenatal death, premature delivery, low birth weight, deformities, and stillbirths.
Health Risks to Unborn Children and Infants • Babies of mothers who smoked during pregnancy or who are exposed to ETS are more likely to die of sudden infant death syndrome (SIDS). • Infants exposed to ETS after birth are twice as likely to die of SIDS.
Reducing Your Risks • Try to establish smoke-free areas in the house or make a rule that smokers go outside. • If a smoker cannot always go outside, air cleaners can help. • If you are visiting a home in which someone smokes, try to stay outside or in a different room as much as possible.
Creating a Smoke-Free Society • When a smoker chooses to smoke, that person makes a decision that affects his or her health, and the health of others. • According to the Surgeon General, the only way to fully protect people from the damaging health effects of ETS is to prohibit smoking in public places. • One of the goals of Healthy People 2010 is to reduce tobacco use and the number of tobacco-related deaths.
