Nicotine • Addictive drug – a substance that causes physiological or psychological dependence • Stimulant – a drug that increases the action of the central nervous system, the heart, and other organs • Raises blood pressure • Increases heart rate • Contributes to heart disease and stroke
Cigarette Smoke • Cigarette Smoke is a Class A Carcinogen (EPA, 1992) • Carcinogen – cancer-causing substance • Tar • A thick, sticky, dark fluid produced when tobacco burns • Destroys cilia – tiny hairlike structures that line the upper airways and protect against infection • Damages the alveoli (air sacs) – which absorb oxygen and rid the body of carbon dioxide • Destroys lung tissue • More susceptible to diseases like bronchitis, pneumonia, emphysema, and cancer • Carbon Monoxide • A colorless, odorless, and poisonous gas • It is easier for blood to hold carbon monoxide instead of oxygen
Harmful Effects of Pipes and Cigars • Cigars contain more nicotine and produce more tar and carbon monoxide than cigarettes • Nicotine in 1 cigar = nicotine in 1 pack of cigarettes • Increased risk of developing cancers of the lip, mouth, and throat
Harmful Effects of Smokeless Tobacco • Smokeless tobacco – tobacco that is sniffed through the nose, held in the mouth, or chewed • NOT safe!!! – contain 28 carcinogens • Delivers nicotine two to three the amount delivered by a single cigarette • Dips/chew 8 to 10 = smoking 2 packs a day • Leukoplakia – thickened, white, leathery-looking spots on the inside of the mouth that can develop into oral cancer • Cancers – throat, larynx, esophagus, stomach, and pancreas
Short-Term Effects of Tobacco Use • Changes in brain chemistry • Increased respiration and heart rate • Dulled taste buds and reduced appetite • Bad breath and smelly hair, clothes, and skin
Long-term effects of tobacco use • Chronic bronchitis • Emphysema • Lung cancer • Coronary heart disease and stroke • Constrict blood vessels • Cuts down on circulation • Plaque build up - Arteriosclerosis
Other consequences • Legal consequences • Social consequences • Financial consequences
Reduced Tobacco Use Among Teens • Antismoking campaigns • Tobacco companies fund • Financial cost • Societal pressures • Family influence
