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

Tar Coated Lung

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
