4. Health Risks of Tobacco Use
Leading cause of preventable death and disability in US
Carcinogen or cancer causing substance
Linked to
Lung disease
Heart disease
Cancers
90% percent of adult smokers started as teens

5. Toxins in Tobacco Nicotine Tar Carbon Monoxide
Many of these products can also be found in paint, rat poison and toilet cleaners

6. Nicotine Addictive drug – causes physical or psychological dependence.
Stimulant – drug that increases the action of the CNS
Raises blood pressure and heart rate

7. Tar Thick, sticky, dark fluid produced when tobacco burns
Paralyzes and destroys cilia
Destroys alveoli
Destroys lung tissues
Leaves smokers susceptible to bronchitis, pneumonia, emphysema, heart disease and cancer

8. Carbon Monoxide Colorless, odorless and poisonous gas
Absorbed more easily than oxygen
Increases risk of high blood pressure, heart disease, hardening of arteries and circulatory deficits

9. Pipes, Cigars and Smokeless Tobacco
Cigars contain more nicotine, tar and CO than cigarettes.
Pipes and cigar smokers have a higher risk of developments cancers of the lips, mouth, throat, larynx, lungs and esophagus.
Smokeless tobacco is no less risky than smoking tobacco because it is absorbed into the lining of the mouth and digestive system.

10. Short Term Effects of Tobacco Use
Brain chemistry changes
Respiration
Increased heart rate
Dulled taste buds
Reduced appetite
Bad breath
Yellowed teeth
Smelly hair, skin and clothes

11. Long Term Effects of Tobacco Use
Chronic Bronchitis
Emphysema
Lung cancer
Coronary heart disease
Stroke
Weakened immune system

12. Other Consequences
Cost to society – tobacco related illnesses cost the US $165 billion each year
Cost to individuals – average smokers spends $1500 a year

24. Health Risks of Tobacco Smoke
Environmental tobacco smoke (ETS) - air that has been contaminated by tobacco smoke
Mainstream smoke – smoke exhaled from the lungs of a smoker and contains lower concentrations of carcinogens
Sidestream smoke – smoke from the burning end of a cigarette, pipe, or cigar.
People exposed to ETS are more likely to develop asthma than their peers who are not exposed.

25. Non - Smokers Secondhand smoke causes
about 3,000 deaths from lung cancer each year
Eye irritations
Headaches
Ear infections
Coughing
Increase risk of coronary heart disease

26. Unborn Children
Smoking during pregnancy can harm the fetus because toxins can diffuse through the placenta to the baby
Nicotine constricts blood vessels
CO reduces O2 levels in the blood of the fetus and mother
Increase risk of miscarriage, premature birth, low birth rate, deformities, stillbirth, growth and developmental problems during childhood

27. Infants
Infants exposed to ETS twice as likely to die of SID, have severe asthma attacks, ear infections, or respiratory tract infections.

28. Young Children
Children of smokers tend to have more sore throats, ear infections, and upper respiratory problems.
Secondhand smoke slows lung development and children who live with smokers may have weaker lungs.
Children who live with smokers are more likely to smoke themselves.

29. Reducing Risk Encourage family and friends to quit
Establish smoke-free areas
Keep windows open and use air cleaners
Meet in public areas
Request non-smoking environments
