Six types of tobacco products • Cigarettes • Chew • Snuff • Pipe • Cigars • Clove/herbal Cigarettes
Nicotine • Addictive ingredient in tobacco • Low doses-mild stimulant and muscle relaxant • Higher doses-powerful nerve poison • 60 mg of nicotine are enough to kill most people. 1 or 2 mg are inhaled when a cigarette is smoked.
TAR • Thick, black substance in tobacco smoke. • Coats inside of airways • Contains many carcinogens
Chemicals • 4000 chemicals in cigarette smoke • 40 of the chemicals are carcinogens (chemical agents that cause cancer)
Six of the dangerous chemicals found in tobacco smoke • Cyanide-poisonous gas used to develop photographs • Formaldehyde-substance used to preserve laboratory animals and as embalming fluid • Lead-dangerous metal
Continued: • Vinyl chloride-flammable gas used to make plastic products • Carbon monoxide-gas that blocks oxygen from getting into the bloodstream • Ammonia-chemical found in bathroom cleaners
Smokeless Tobacco • Snuff • Chewing tobacco • They contain: nicotine, tar, arsenic, nickel, benzopyrene, polonium • They lead to mouth sores, mouth cancer
Short term effects(1 second for inhaled nicotine to get into the bloodstream) • Stimulates brain reward system • Increases heart rate and blood pressure • Increases breathing rate • Increases blood sugar levels • Stimulates the vomit reflex
Long term effects • 1. Addiction-changes the way the brain reward system functions • 2. Bronchitis-paralyzes then kills cilia so mucus builds up in lungs • 3. Emphysema-air cannot move in and out of the lungs because alveoli are damaged
4. Heart and Artery Disease • Nicotine increases heart rate, narrows blood vessels and eventually causes arteries to become hardened and clogged • Nearly 170,000 die yearly
5. Cancer • Types that can be caused from tobacco: Lung, Pancreas, Bladder, Cervix, Kidney, Oral, and Throat • Lung cancer often spreads to other parts of the body; leading cancer killer
6. Immune System Suppression • Reduces the activity of immune system • Leads to susceptibility to disease
7. Other • Excess stomach acid build up • Damage to stomach and small intestines • Stains on fingers and teeth • Mouth sores • Odor and tar film on clothes • Dulls senses of smell and taste
Effects of Smoke on Nonsmokers • Sidestream smoke - smoke that escapes from the tip of a cigarette, cigar, or pipe • Mainstream smoke - smoke that is inhaled through a tobacco product and exhaled by a tobacco smoker • Environmental tobacco smoke (second hand smoke) - both of the above
Dangers of Second hand smoke • Lung cancer-for every 8 smokers killed by their own smoking, 1 non-smoker is killed by exposure • Headaches, nausea, dizziness, reduced heart functions, asthma
Smoking during Pregnancy • Chemicals pass through placenta to fetus and affect fetus the same way they affect the mother • Can lead to miscarriage, premature birth, low birth weight • Baby at risk for SIDS • Can affect fetus brain development • May be addicted to nicotine at birth
Tobacco and Family • Over $1,500 per year for buying tobacco products • Lost wages due to illness • Medical bills • Funeral costs (20% of premature deaths in the US are caused by tobacco use
Tobacco and Society • Estimated $138 billion per year (related to medical care that cannot be paid) • Insurance costs go up • Accidental fires
Law • Cannot sell to anyone under 18
