Objectives • Identify 3 factors that influence teens’ decisions about tobacco use • Describe the various forms of tobacco products
DO NOW • What does this graph reveal about the popularity of smoking among teenage smokers?
Then vs. Now • Your parents lived in a much smokier environment • People smoked on planes, in movie theatres, restaurants, and at work • Today we know A LOT more about the dangers of smoking • As a result, tobacco use has fallen • It is not as socially acceptable as it once was
Why Teens Use Tobacco • Friends • Family • Media
Influence of Friends • Most people who become addicted start in their teens • Teens that have friends who smoke are more likely to start themselves • Peer pressure • If a teen has friends that do not smoke, they are less likely to start • Most teens credit their friends for helping them resist the urge to smoke
Influence of Family • Family may have warned you about the dangers of tobacco • Positive role models • Children of smokers are much more likely to start smoking, even if their parents discourage them • They see smoking as a behavior related to adulthood • They assume they will use tobacco just like their parents
Influence of Media • ANTI-tobacco ads may have influenced you to not smoke • You most likely have heard the dangers of smoking on TV or in a magazine
Tobacco Products • Made from dried, processed leaves of the tobacco plant • They produce a chemical that acts as an insecticide • Nicotine • Very addictive • In pure liquid form it is extremely poisonous • Infant deaths
Products That Are Smoked • When the tobacco is processed for these products, preservatives, flavorings, and other substances may be added, some of which contribute to the harmful effects of smoking • Cigarettes • E-Cigarettes • Cigar Tobacco • Pipe Tobacco
Smokeless Tobacco • Tobacco that is chewed, placed between the lower lip and teeth, or sniffed through the nose • Contains many of the same chemicals found in tobacco smoke, including nicotine • Chewing tobacco – “dip” or “chew” • Poor quality, ground tobacco, mixed with flavors, preservatives, and chemicals • Snuff • Finely ground, powdered tobacco • Mouth or sniffed through nose
Vocabulary • Nicotine– an extremely addictive chemical in tobacco products. • Smokeless Tobacco – tobacco products that are chewed, placed between the lower lip and teeth, or sniffed.
Vocabulary • Chewing Tobacco – a smokeless tobacco product that consists of poor-quality, ground tobacco leaves and is placed between the gum and cheek. • Snuff– a smokeless tobacco product that consists of dry or moist powder. It may be placed between the lower lip and teeth or sniffed.
Vocabulary • Stimulant– drug that increases the activity of the nervous system • Tar– the dark, sticky substance that forms when tobacco burns • Carcinogen– cancer causing agents • Carbon Monoxide – an odorless, poisonous gas produced when tobacco is burned
Nicotine’s Short Term Effects • Increased heart rate • Increased blood pressure • Changes in the brain that may lead to addiction
Nicotine Addiction • People rely on tobacco for feelings of alertness and pleasure • Ongoing use leads to the development of a tolerance • Therefore, the more a person uses tobacco, the bigger their tolerance will become • This will eventually lead to nicotine addiction
Nicotine Withdrawal • If a nicotine addict goes without nicotine for even a short while, he or she may experience withdrawal symptoms • Symptoms include: • Headaches • Irritability • Difficulty sleeping • Inability to concentrate • Intense nicotine cravings
What’s in a Cigarette? • There are approximately 600 ingredients in cigarettes • When burned, they create more than 4,000 chemicals • At least 50 of these chemicals are known to cause cancer, and many are poisonous • Many of these chemicals are also found in consumer products, but these products have warning labels • While the public is warned about the danger of the poisons in these products, there is no such warning for the toxins in tobacco smoke
Here are a few of the chemicals in tobacco smoke, and other places they are found… • Acetone – found in nail polish remover • Acetic Acid – an ingredient in hair dye • Ammonia – a common household cleaner • Arsenic – used in rat poison • Benzene – found in rubber cement • Butane – used in lighter fluid • Cadmium – active component in battery acid • Carbon Monoxide – released in car exhaust fumes • Formaldehyde – embalming fluid • Hexamine – found in barbecue lighter fluid • Lead – used in batteries • Napthalene – an ingredient in moth balls • Methanol – a main component in rocket fuel • Nicotine – used as insecticide • Tar – material for paving roads • Toluene - used to manufacture paint
Short Term Effects of These Chemicals • Brown stains on fingers and teeth • Smelly hair and clothes • Bad breath • Receding gums and tooth decay • Paralysis of cilia lining the airways • Increased respiratory infections (colds, flu) • Impaired lung function (reduced athletic ability)
Vocabulary • Chronic Obstructive Pulmonary Disease (COPD) – a disease that results in gradual loss of lung function • Chronic Bronchitis – a condition in which the bronchi in the lungs are constantly swollen and clogged with mucus • Emphysema – a disorder in which damaged alveoli in the lungs can no longer take in adequate oxygen and eliminate carbon dioxide
Vocabulary • Leukoplakia – white patches on the tongue or lining of the mouth that may become cancerous • Mainstream Smoke – smoke that is exhaled from a smokers lungs • Sidestream Smoke – smoke that goes directly into the air from a burning tobacco product • Secondhand Smoke – a combination of mainstream smoke and sidestream smoke
Long Term Risks • Tobacco is the leading cause of preventable death in the US • Cigarette smoking is responsible for 400,000 deaths a year in the US • Tobacco users increase their risk of developing respiratory diseases, cardiovascular diseases, and several forms of cancer
Respiratory Diseases • “Smoker’s Cough” • Results from damage done by tar • Tar sticks to the cilia in the in the respiratory tract and prevent them from moving • This results in mucus and particles to be pushed into the lungs instead of the throat to be swallowed • The cough comes from trying to clear the airway
Respiratory Diseases • Tobacco smoke and other toxins also irritate the lining of the bronchi • The bronchi are tubes that carry air between the trachea and the lungs • They become inflamed • This restricts the amount of air let into the lungs
Smoking Also Leads To… • Increased risk of stomach ulcers • Slower healing of injuries • Increased colds and flu • Increased allergies and asthma • A constant runny nose • Frequent headaches • Dulled sense of taste and smell • Premature wrinkling
Cardiovascular Disease • Diseases of the heart and blood • Kills 140,000 smokers a year • The combined effects of nicotine, tar, and carbon monoxide force the cardiovascular system to work harder to deliver oxygen throughout the body
Cardiovascular Disease • A smoker is 3 times more likely than a nonsmoker to have a heart attack • Cigarette smoking doubles a persons chances of having a stroke • Smokers are 10 times more likely to develop circulation problems in blood vessels that carry blood to the entire body
Cancer • Tobacco use is a major factor in the development of lung cancer, oral cancers, and several other cancers
Lung Cancer • Leading cause of cancer death for men and women • 85% of lung cancer deaths are related to smoking • By the time most lung cancers are diagnosed, successful treatment is unlikely • Only 15% of lung cancer patients survive for more than 5 years
Oral Cancer • Cancer of the mouth, tongue, and throat • 90% of oral cancers occur from people using tobacco • The survival rate is higher than lung cancer • However, surgery to remove the cancer can be disfiguring
Other Cancers • Tobacco users also have an increased risk of cancers of the: • Esophagus • Larynx • Stomach • Kidneys • Pancreas • Bladder • Blood • Other sites
Secondhand Smoke • Long term exposure to secondhand smoke can cause cardiovascular disease, many respiratory problems, and cancer • Secondhand smoke causes 50,000 deaths from heart attacks and lung cancer each year • Each year, secondhand smoke contributes to about 300,000 respiratoryinfections in children youngerthan 18 months
