2  What are some harmful effects of smoking tobacco products?  What substance in tobacco causes a person to become addicted?

3  Addictive Drug: a substance that causes physiological of psychological dependence  Nicotine: the addictive drug found in tobacco leaves  Stimulant: a drug that increases the action of the central nervous system, the heart, and other organs  Carcinogen: a cancer-causing substance  Tar: a thick, sticky, dark fluid produced when tobacco burns  Carbon Monoxide: a colorless, odorless, and poisonous gas  Smokeless Tobacco: tobacco that is sniffed through the nose, held in the mouth, or chewed  Leukoplakia: thickened, white, leather-looking spots on the inside of the mouth that can develop into oral cancer

4  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  All 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  Tobacco is a carcinogen or cancer-causing substance  Tobacco smoke contains tar and carbon monoxide  It also contains the same poisonous compounds found in products such as paint, rat poison, and toilet cleaner.

7  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  Poisonous gas found in cigarette smoke  Absorbed more easily than oxygen  Deprives the body’s tissues and cells of oxygen  Increases the risk of high blood pressure, heart disease, hardening of the arteries, and other circulatory problems

9  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  Smokeless 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  Brain 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 increase  Taste buds are dulled and appetite is reduced  Users have bad breath, yellowed teeth, and smelly hair, skin, and clothes.

12  Chronic Bronchitis  Emphysema  Lung Cancer  Coronary heart disease and stroke  Weakened immune system

13  Costs 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

18  Nicotine withdrawal: the process that occurs in the body when nicotine is no longer used  Nicotine 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.

19  Falsely believe that smoking will help control weight or releive stress  Some think smoking will make you mature and independent  Teens are influenced by movies, TV, advertisements, or media messages  Truth: Smoking reduces the body’s capacity for physical activity, so it may lead to weight gain.  Health problems caused by tobacco use can increase the user’s stress level

20  CDC reports that 77 % of high school students nationwide do not smoke  Tobacco legislation: 1998 tobacco companies and 46 states reached a legal settlement that restricts tobacco advertising aimed at teens  Tobacco companies are required to fund ads discouraging teens from smoking.  Illegal for anyone under the age of 18 to purchase tobacco products in the US.  Legislation has limited smoking in public places and businesses.

21  Better cardiovascular endurance and lung function  Improved fitness level and athletic performance  Reduce your risk of lung cancer, heart disease, and stroke.  Look and feel better

22  Common to experience nicotine withdrawl  Symptoms include irritability, difficulty concentrating, anxiety, sleep disturbances, and cravings for tobacco  Use nicotine substitutes to relieve symptoms: Gum, patches, nasal sprays, and inhalers  Some are over-the-counter products; others require a doctor’s prescription

23  Prepare for the quit day: set target date and stick to it.  Get support and encouragement  Access professional health services  Replace tobacco use with healthy behaviors

24  Promoting a Smoke-Free Environment

25  Environmental Tobacco Smoke (ETS) : or secondhand smoke, air that has been contaminated by tobacco smoke  Mainstream Smoke: the smoke exhaled from the lungs of a smoker  Sidestream Smoke: the smoke from the burning end of a cigarette, pipe, or cigar.

26  ETS from cigarettes, cigars, and pipes contains more than 4,000 chemical compounds.  More than 50 of those chemicals are cancer- causing carcinogens  Infants and young children who are exposed to ETS are more likely to develop asthma than their peers who are not exposed to ETS  Secondhand smoke causes 3,000 deaths from lung cancer every year.

27  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  Many states now prohibit smoking in any workplace  Healthy 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.
