They believe they can quit at any time— addictive nicotine (the addictive drug) Numerous chemicals and additives stimulant (drug that increases the action of the central nervous system, heart and other organs) Tar- thick, sticky, dark fluid produced when tobacco burns Carcinogens – substances in tar, cancer causing substances Carbon monoxide colorless, odorless, poisonous gas in cigarette smoke which passes through the lungs into the blood Over 12 million Americans are regular smokeless tobacco users Smokeless tobacco carries many of the same health risks as cigarettes (addiction to nicotine) Other risks: mouth sores (can turn to cancer of the lip, mouth, or throat), damage to teeth and gums, damage to the digestive system Which method gets nicotine into the bloodstream faster? smoking or chewing? smoking pipes or cigars inhale less smoke—but more likely to develop cancers of the lip, mouth, and throat because more tar and chemicals are generated by pipes and cigars. Short term effects- immediately after lighting up Long-term effects – occur as the smoking continues 2 primary diseases associated with smoking chronic bronchitis and emphysema Chronic bronchitis- condition in which the bronchi are irritated. The tar from cigarettes builds up and causes chronic coughing and excessive mucus secretion. Emphysema- a condition that involves the destruction of the tiny air sacs in the lungs through which oxygen is absorbed into the body. We use 5% of our energy to breathe, but emphysema causes one to use 80% of their energy to breathe. Lung cancer- directly linked to cigarette smoking and is the leading cause of cancer deaths among males. Increasing in females! Nicotine makes the heart work harder and speeds up pulse. It also constricts blood vessels, which cuts down on circulation or blood flow Smoking raises blood pressure which leads to stroke Smokeless tobacco is just as addictive as smoking Chewers secret more saliva. Although the excess is usually spit out, some is unconsciously swallowed. This introduces tar and other harmful chemicals into the digestive and urinary systems. Leukoplakia- thickened white, leathery-appearing spots on the inside of a smokeless tobacco user’s mouth that can develop into cancer of the mouth. 30,000 Americans annually get oral cancer; only about 50% of these people survive longer than 5 years. Just as dangerous Passive smoke- cigarette, cigar, or pipe smoke inhaled by nonsmokers as well as smoke than remains in a closed environment after the smoker is through smoking Mainstream smoke- the smoke that a smoker blows off Side stream smoke, the smoke that comes from burning tobacco Write about your feelings concerning the smoking ban.
