***What’s in a Cigarette?

1. Cyanide2. Formaldehyde

3. Arsenic4. Nicotine

•Each puff of a cigarette contains more than 43 carcinogens.

***Nicotine

•Stimulant•Addictive• Increases BP• Increases HR

•Destroys cilia• Low tar cigarettes are still harmful to the smoker because the smoker tends to inhale more deeply and smoke more

***Tar

***Tobacco use is linked to…• Increased risk of heart disease• Increased risk of stroke• Chronic bronchitis• Emphysema• Increased risk of many types of cancer

•High BP• Impotence•Premature wrinkling of the skin

Other Forms of Tobacco

•Cigar•Pipe

•Pipe and cigar smoking• Inhale less•More likely to develop cancers to the lip, throat, and mouth• ***More tar is generated by pipes and cigars

Respiratory Diseases

•Chronic Bronchitis

•A condition in which the bronchi are irritated•Cilia becomes useless•Tar from cigarette smoke builds up which result in chronic coughing and excessive mucous secretions

Emphysema• The destruction of the tiny air sacs in the lungs • The walls of the air sacs are destroyed and provide less total surface area which oxygen can be absorbed•More breaths are required•Healthy individual uses 5% energy to breath• Advanced emphysema patients uses 80% energy to breath

***Lung Cancer•Directly linked to smoking•#1 cause of cancer deaths in men• Begins as the bronchi are irritated by cigarette smoke• Cilia are destroyed• Extra mucous can not be expelled• Smoker develops a cough• Cancerous cells begin to grow• Cancer cells travel to other organs

***Circulatory System

• Increase HR•3x greater risk of heart attack• Increase BP• Increases Cholesterol

***Smokeless Tobacco

•Nicotine in smokeless tobacco is as addictive as that in cigarettes•People who chew or dip secrete more salvia

•Oral cancer strikes about 30,000 Americans annually (only 50% of its victims survive longer than 5 years)

•Greater tooth wear•Gums pushed away from their teeth•Roots of gum exposed•Bad breath

•Discolored teeth•Decrease in the users ability to smell and taste especially sweet and salty foods

HealthRisks

***Smoking During Pregnancy

• Associated with small fetal growth• Increased chance of spontaneous abortion• Prenatal death/Increased still born birth• Carbon monoxide reduces the oxygen levels in the mother’s and fetus’ blood

•***Sidestream Smokethe smoke that comes from a burning cigarette. (This has higher concentrations of carcinogens)•***Mainstream Smokethe smoke the smoker blows off•***Second hand smokeit is both Mainstream/Sidestream smoke
