1 Chapter 20, Lesson 1 The Health Risks of Tobacco Use
2 Health Risks of Tobacco Use About 23% of high school students and 10% of middle school students are current smokersAbout 1/3 of children and teens who try cigarettes become regular smokersAbout 9.9% of high school boys and 1.2% of high school girls use smokeless tobacco
3 All forms of tobacco contain chemicals that are dangerous to your health Addictive drug – stimulantNicotineTarCarbon MonoxideSmokeless TobaccoCarcinogenLeukoplakiaHarmful Effects – long- and short-termOther consequences…
4 Addictive Drug - A substance that causes physiological or psychological dependence Nicotine - An addictive drug found in all tobacco leaves (used in all tobacco products)Stimulant - A drug that increases the action of the central nervous system, the heart, and other organs ( blood pressure, heart rate)Carcinogen - A cancer-causing substance (same poisonous compounds found in rat poison, paint, and toilet cleaner)
5 Tar- A thick, sticky, dark fluid produced when tobacco burns (how does this cooperate with your pink, healthy lungs?)Carbon Monoxide - A colorless, odorless, and poisonous gas (deprives body tissue and cells of oxygen – how do you breathe?)Smokeless Tobacco - Sniffed through the nose, held in the mouth, or chewed (sometimes called “spit” – absorbed into blood through mucous membranes)Leukoplakia - Thickened, white, leathery-looking spots on the inside of the mouth; can develop into oral cancer
6 Short-term and Long-term effects Brain chemistry changesChronic BronchitisRespiration and Heart rate increaseEmphysemaTaste buds are dulled/appetite reducedLung cancerBad breath and yellow teethCoronary heart diseaseSmelly hair, skin, clothesWeakened immune system
7 Other Consequences of Tobacco Use Costs to societyIn U.S., lost work/productivity - about $165 billion/yearCost to individualOne pack a day ($4-$11 approx.) for 1 year = ?Legal consequencesSelling cigarettes to someone under age 18 is illegal. Using tobacco products on school campus will lead to suspension.
8 Chapter 20, Lesson 2 Choosing to Live Tobacco-Free
9 Teens and Tobacco Why do some teens begin to smoke? Actually… falsely think it will help control weightcope with stressseem more mature and independentActually……smoking reduces capacity to physical activity (leads to weight gain)…nicotine dependency leads to stress levels…Media influences behaviors; is it glamorous or make you look cool?
10 Reduced Tobacco Use Among Teens Tobacco Legislation– 1998 legal settlement restricting tobacco advertising aimed at young people; also required to fund ads that discourage smokingNo Smoking policies – limited smoking areas (restaurants, airports, public places)Family Values– if parents don’t smoke more than likely you won’t eitherPositive Peer pressure – healthy role modelsHealth risks – knowledge is power; understanding about diseases and health problems
11 Benefits of Living Tobacco-Free Better cardiovascular endurance and lung functionImproved fitness level and athletic performanceReduced risk of lung cancer, heart disease, and strokeImproved mental/emotional state – not dependent on drug – sense of freedom!Less stress (less worry)More confidence in social situationsYou look and feel better!!
13 Health Risks of Tobacco Smoke Environmental tobacco smoke (ETS) – also known as “second- hand smoke” is air contaminated by tobacco smokemainstream smoke - smoke exhaled from lungs of a smokersidestream smoke - smoke from the burning end of a cigarette, pipe, or cigarWhich type of smoke is more dangerous? Why?
14 ETS from cigarettes, pipes, or cigars contain more than 4,000 chemical compounds, 50 of those are carcinogenic (cancer-causing) Second-hand smoke causes about 3,000 deaths from lung cancer each year. ETS causes eye irritations, headaches, ear infections, coughs; it worsens asthma and other respiratory problems and increases coronary heart disease
15 Health Risks to Unborn Children and Infants Smoking during pregnancy:impaired fetal growthspontaneous miscarriageprenatal deathpremature deliverylow birth weightdeformitiesstillbirthSIDS (sudden infant death syndrome)severe asthma attacks, ear infections, respiratory tract infectionsNicotine passes through placenta (constricting blood vessels)Carbon monoxide reduces oxygen levels in the blood
16 Health Risks to Young Children Children of smokers:higher levels of poor overall healthmore sore throats, ear infections, upper respiratory problemsslows lung development (weaker lungs)children learn by example…ETS (second hand smoke)
17 Creating a Smoke-Free Society Healthy People 2010: reduce tobacco use and related deathsIn most states, it is illegal to sell tobacco to teens (under 18 years of age); illegal to smoke in public placesCommunity activities that promote healthy lifestylesEncourage others to avoid tobacco use
