Ch Key Terms Nicotine- the highly addictive drug that is found in all tobacco products Carcinogen- any chemical or agent that causes cancer Tar- sticky, black substance in tobacco smoke that coats the inside of the airways and that contains many carcinogens Carbon monoxide- a gas that blocks oxygen from getting into the bloodstream
Chemicals in Tobacco A stimulant More than 4000 chemicals 10% are carcinogens or poisonous Carcinogens are cancer causing agents The 3 most poisonous chemicals are: tar, nicotine, and carbon monoxide
Nicotine Psychoactive substance- causes a change in the person’s mood or behavior Very addictive- causes a physical dependence
Tar Tiny pieces that when inhaled in to the lungs, condense and form a sticky coating on the bronchial tubes Same substance used to pave roads!!! Destroys cilia, waving hair-like projections that work to keep the respiratory tract clear.
Carbon Monoxide A colorless, odorless, poisonous gas released by burning tobacco Interferes with the blood’s ability to carry oxygen Same gas from car exhaust –if inhaled directly-can be fatal
Other Chemicals in Tar
2 Leading causes of death due to cigarette smoke 1)Lung cancer 2)Heart disease
Ch Key Terms Emphysema- respiratory disease in which air can not move in & out of the alveoli because they become blocked or lose their elasticity Sidestream smoke- smoke that escapes from the tip of a cigarette, cigar, or pipe Mainstream smoke- smoke that is inhaled through a cigarette & then exhaled by a cigarette smoker Environmental tobacco smoke (secondhand smoke)- a combination of exhaled mainstream smoke & sidestream smoke
Mainstream smoke Smoke that is inhaled through a cigarette and then exhaled by a cigarette smoker
Sidestream smoke Smoke that escapes from the tip of a cigarette, cigar, or pipe This contains 2x more nicotine and tar, and 5x more CO than mainstream Non-smokers who live with smokers have a % HIGHER risk of dying from heart disorders than non- smokers who live with non-smokers!!!
Passive smoker- a person who inhales the sidestream smoke –smoke inhaled by non- smokers Passive smoke can cause: Heart disease*Asthma Eye irritation*Cancer Ear infections Emphysema

LUNG CANCER growth of malignant cells that attack and replace healthy cells NO CURE!! Now kills more women than breast cancer! Many females believe smoking causes weight loss-There is NO PROOF of this being true!
Chronic Bronchitis –Inflammation of the bronchial tubes, combined with built up particles –Chronic coughing, excessive mucus production –Cilia becomes useless-covered with tar
Pulmonary Emphysema Pulmonary=LUNGS Destruction of tiny air sacs in lungs which absorb oxygen into the body Tiny air sacs=ALVEOLI Instead of using only 5% of their energy to breathe, a person with advanced emphysema may use 80% of their energy to breathe!!
Chronic Obstructive Pulmonary Disorder Combination of chronic bronchitis and obstructive emphysema
Sudden Infant Death Syndrome (SIDS) Condition is which infants die in their sleep for unknown reasons Second Hand Smoke Anti Smoking PSA - VideoSecond Hand Smoke Anti Smoking PSA - Video
