2 Tobacco Use-A Serious Health Risk Tobacco Use is the #1 cause of preventable disease and death in the US. It is attributed to roughly 438,000 deaths per year, or 1 out of 5 deaths overall. Worldwide, tobacco use causes more than 5 million deaths per year. On average, adults who frequently smoke cigarettes die 14 years earlier than nonsmokers. Addictive drug-is a substance that causes, physiological or psychological dependence. (Physiological=body, Psychological =mind) Nicotine=the addictive drug found in tobacco products. It is classified as a Stimulant-which is a drug that raise blood pressure, increase heart rate, and contributes to heart disease and strokes.

3 Cigarette Smoke-A toxic mix Carcinogens-are cancer causing substances Tar-a thick, sticky, dark fluid produced when tobacco burns Carbon monoxide-a colorless, odorless, and poisonous gas. When smoking Carbon monoxide is taken up more by the blood than oxygen, thereby depriving the cells of oxygen. Prune juice can be added a flavoring There are more than 4000 toxic chemicals in Cigarettes

Health risks include but are not limited to: Lip and throat cancer, damage to teeth and gums and digestive system. Leukoplakia-Thickened white, leathery looking spots on the inside of the mouth.

5 How about a Dip…? Leukoplakia

6 Short Term Affect on the body Changes Brain chemistry- body craves more Withdrawal symptoms In a s little as 30 minute after last use. Increased respiration and heart rate Dulled taste buds Bad breath, smelly clothes, hair, and skin

7 Long Term Affects on the body Diseases of the Respiratory System (Lungs) A. Chronic Bronchitis: is an irritation of the bronchi. The cilia become useless; tar builds up causing a chronic cough and excessive mucus. B. Emphysema: is a condition which destroys the tiny air sacs in the lungs. These air sacs are needed to absorb oxygen into the blood stream. A person with advanced emphysema can use up to 80% of their energy just to breath. C. Lung Cancer: is the leading cause of caner deaths in males. Cilia are destroyed and extra mucus can not be expelled. Cancer cells grow in these conditions, block the bronchi and move into the lungs. African Americans tend to suffer most from Tobacco related lung caner

8 Diseases of the Circulatory System (Heart) Nicotine makes the heart work harder and speeds up the pulse. Smoking constricts the blood vessels, which cuts down on circulation. Nicotine contributes to plaque build up in blood vessels. This leads to hardening of the arteries. This condition increases the risk of a heart attack. Nicotine also increases blood pressure and can lead to strokes.

9 Nervous System Addiction Increase risk of strokes- which occur in the Brain

10 Digestive system Possible mouth, pharynx, larynx, stomach, pancreas cancers Increased nausea, diarrhea
