1. The Glamour of Smoking

2. Effects of Smoking on the Body
Smoking causes 1 in 5 deaths in U.S.
One in two lifetime smokers will die from their habit
Smoking damages every system in the body
Smoking leads to cancer of the lungs, throat, mouth, trachea, larynx, stomach, pancreas, kidneys, and bladder
Smoking increases stickiness of blood & build-up of fatty deposits on artery walls, increasing risk of Coronary Artery Disease, heart attack, & stroke
Smoking increased risk of ulcers
Lower sperm count & increase of deformed sperm

3. Effects of Smoking on the Body
Risk of lung cancer is 23 times higher in smokers than non-smokers
Smoking raises blood pressure & pulse rate
Smoking decreases circulation to fingers & toes, sometimes necessitating amputation
Smoking leads to emphysema, chronic bronchitis, and other debilitating respiratory diseases
Smoking during pregnancy can lead to stillborns, miscarriages, and newborn defects
Smoking reduces bone density, leading to osteoporosis

4. Lip cancer from smoking
Smoker’s gum disease

5. Effects of Smoking on Lifestyle
Causes yellowing of teeth and fingers
Increases cough & lung infection due to damage to cilia in trachea
Accelerates aging & wrinkling of skin
Causes damage to larynx (voicebox)
Increases impotence (due to decreased circulation to necessary parts)
Leaves lingering odor on clothing and environment
Decreases sense of taste and smell
Is expensive!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

7. Cigarettes
Cigarettes contain ~4000 chemicals, 60 of which cause cancer
Cigarettes contain tar, carbon monoxide, cyanide, arsenic, lead, and radioactive compounds
Cigarette tar coats your lungs like soot coats a chimney
A pack-a-day smoker smokes 7300 cigarettes per year for $700

8. Profile of Some Cigarette Chemicals
Formaldehyde: used to preserve dead bodies in funeral homes (used in biology specimens)
Carbon Monoxide: toxic gas in car exhaust – often used to commit suicide
Tar: one cup/year coats the lungs of a smoker
Hydrogen Cyanide: poison gas used to kill enemies in WWI
Acetone: fingernail polish remover – used to suffocate insects in this class
Arsenic: a preservative & pesticide that can cause death through multi-system failure
Nicotine: addictive drug – one drop can kill a person

9. Effects of Smoking on the Respiratory System
Lung damage from the build-up of dangerous substances in lungs and airway
Lung damage due to decreased ability to clear mucus & debris from airway & lungs
Increased risk of lung infection
Decreased elasticity of alveoli, and inability to expel sufficient air on exhalation

10. Healthy Lung vs. Smoker’s Lung

11. Smoker’s Lungs

12. COPD & Lung Cancer Evidence of Smoking’s Harmful Effects
Group of disabling diseases where the lungs & lung tissue have been destroyed
Emphysema, chronic bronchitis
Characteristics:
Almost always caused by smoking
Progressive inability to breath
Coughing & frequent lung infections
Chronic hypoxia (lack of oxygen)

13. Emphysema “Pink Puffers”
Loss of lung elasticity due to smoking makes expelling air very difficult
Exhalation takes great effort & energy
Carbon dioxide becomes trapped in lungs, leaving no room for oxygen
Patients develop barrel-chest & must be on oxygen all the time

14. Chronic Bronchitis “Blue Bloaters”
Irritated & inflamed mucosa generate excess mucus
Damage to trachea decreases ability to expel mucus from airway
Excess mucus impairs ability to breath
Infection is common & cyanosis is obvious

15. Lung Cancer One third of all cancer deaths
Number of deaths from lung cancer are constantly increasing
Most lung cancer is very aggressive and metastasizes very rapidly
Low survival rate due to late diagnosis
Average survival time after diagnosis is 9 months
Over 90% of lung cancer victims are smokers

16. Healthy Lung Cancerous smoker’s lung
