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

Toxins in Tobacco

• Nicotine

• Tar

• Carbon Monoxide

Many of these products can also be found in paint, rat poison and toilet cleaners

Nicotine

• Addictive drug – causes physical or psychological dependence.

• Stimulant – drug that increases the action of the CNS

• Raises blood pressure and heart rate

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

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

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.

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

Long Term Effects of Tobacco Use

• Chronic Bronchitis• Emphysema• Lung cancer• Coronary heart disease• Stroke• Weakened immune system

Other Consequences

• Cost to society – tobacco related illnesses cost the US $165 billion each year

• Cost to individuals – average smokers spends $1500 a year

• Legal consequences – selling tobacco to people under 18 is illegal.

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.

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

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

Infants

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

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.

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
