3 VocabularyAddictive Drug: a substance that causes physiological of psychological dependenceNicotine: the addictive drug found in tobacco leavesStimulant: a drug that increases the action of the central nervous system, the heart, and other organsCarcinogen: a cancer-causing substanceTar: a thick, sticky, dark fluid produced when tobacco burnsCarbon Monoxide: a colorless, odorless, and poisonous gasSmokeless Tobacco: tobacco that is sniffed through the nose, held in the mouth, or chewedLeukoplakia: thickened, white, leather-looking spots on the inside of the mouth that can develop into oral cancer
4 Health Risks of Tobacco Use All tobacco products display warning labels stating that using tobacco products can be harmful to an individual’s health.Medical studies have shown that tobacco use is the leading cause of preventable dealth and disability in the United States.Smoking has been linked to lung disease, cancers, and heart disease.About 90 % of adult smokers began the habit as teenagers.
5 NicotineAll tobacco products contain nicotine, the addictive drug found in tobacco leaves.Nicotine is a stimulant, a drug that increases the action of the central nervous system, the heart, and other organs.Using nicotine raises blood pressure, and increases the heart rate
6 Poisonous Substances in Tobacco Smoke Tobacco is a carcinogen or cancer-causing substanceTobacco smoke contains tar and carbon monoxideIt also contains the same poisonous compounds found in products such as paint, rat poison, and toilet cleaner.
7 Tar Tar is a thick, sticky, dark fluid produced when tobacco burns. Tar damages a smoker’s respiratory system by destroying the structures of the airway that protect the body against infection.Tar also destroys the alveoli, or air sacs, which absorb oxygen and rid the body of carbon dioxide.Smokers are susceptible to diseases such as bronchitis, pneumonia, emphysema, heart disease, and cancer.87 % of cancer deaths result from smoking
8 Carbon Monoxide Poisonous gas found in cigarette smoke Absorbed more easily than oxygenDeprives the body’s tissues and cells of oxygenIncreases the risk of high blood pressure, heart disease, hardening of the arteries, and other circulatory problems
9 Pipes, Cigars, Smokeless Tobacco Cigars contain significantly more nicotine and produce more tar and carbon monoxide than cigarettes.One cigar can contain as much nicotine as an entire pack of 20 cigarettes.Pipe and cigar smokers also increase the risk of developing cancers of the lips, mouth, throat, larynx, lungs, and esophagus.Smokeless tobacco (spit) are not a safe alternative to smoking.The nicotine and carcinogens in these products are absorbed into the blood through the mucous membranes in the mouth or the digestive tract.
10 LeukoplakiaSmokeless tobacco are absorbed into the body at levels up to tree times the amount of a single cigarette.Smokeless tobacco irritates the sensitive tissues of the mouth causing leukoplakia that can develop into oral cancer.Smokeless tobacco causes cancers of the mouth, throat, larynx, esophagus, stomach, and pancreas.8-10 plugs of tobacco daily = two packs of cigarettes
11 Short-Term EffectsBrain Chemistry changes: body craves more of the drug. Withdrawal symptoms include headaches, nervousness, and trembling as soon as 30 minutes after last use.Respiration and heart rate increaseTaste buds are dulled and appetite is reducedUsers have bad breath, yellowed teeth, and smelly hair, skin, and clothes.
12 Long-Term Effects Chronic Bronchitis Emphysema Lung Cancer Coronary heart disease and strokeWeakened immune system
13 Tobacco CostsCosts to society: Tobacco-related illnesses cost the US about $165 billion each year.Costs to individuals: A person smoking one pack of cigarettes a day will spend $1,500 a year.Legal consequences: selling to minors, smoking is a non-smoking environment or on school or government property
17 Choosing to Live Tobacco-Free LESSON 2Choosing to Live Tobacco-Free
18 VocabularyNicotine withdrawal: the process that occurs in the body when nicotine is no longer usedNicotine Substitutes: products that deliver small amounts of nicotine into the users system while he or she is trying to give up the tobacco habit.Tobacco cessation program: a course that provides information and help to people who want to stop using tobacco.

24 Promoting a Smoke-Free Environment Lesson 3Promoting a Smoke-Free Environment
25 VocabularyEnvironmental Tobacco Smoke (ETS) : or secondhand smoke, air that has been contaminated by tobacco smokeMainstream Smoke: the smoke exhaled from the lungs of a smokerSidestream Smoke: the smoke from the burning end of a cigarette, pipe, or cigar.
26 ETSETS from cigarettes, cigars, and pipes contains more than 4,000 chemical compounds.More than 50 of those chemicals are cancer- causing carcinogensInfants and young children who are exposed to ETS are more likely to develop asthma than their peers who are not exposed to ETSSecondhand smoke causes 3,000 deaths from lung cancer every year.
27 Health Risks to Unborn Children and Infants Smoking during pregnancy can seriously harm the developing fetus.Nicotine and carbon monoxide constrict the blood vessels and reduce oxygen levels in the blood of the mother and fetus.Leads to impaired fetal growth, spontaneous miscarriage and prenatal death, premture delivery, low bieth weight, deformities, and stillbirths.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 and may have severe asthma attacks, ear infections, or respiratory tract infections.
28 Create a Smoke-Free Socitey Many states now prohibit smoking in any workplaceHealthy People 2010 goal is to reduce tobacco use and the number of tobacco related deaths.States and local communities are supporting the efforts to create a smoke-free society.
