1. Chapter 21 Tobacco

2. Tobacco is the #1 cause of preventable disease in the United States Everyday teens and adults begin to use some form of tobacco and quickly become addicted

3. The adverse health effects from cigarette smoking account for an estimated 480,000 deaths, or nearly one of every five deaths, each year in the United States More deaths are caused each year by tobacco use than by all deaths from human immunodeficiency virus (HIV), illegal drug use, alcohol use, motor vehicle injuries, suicides, and murders combined On average, someone who smokes a pack or more of cigarettes a day lives seven years less than someone who never smokes Smoking Statistics

4. Statistics Cont’d. Smokers are more likely to develop heart disease, stroke, and lung cancer. Smoking is estimated to increase the risk— For coronary heart disease by 2-4 times (leading killer in US) For stroke by 2-4 times Of men developing lung cancer by 25 times Of women developing lung cancer by 26 times Cancer almost anywhere in your body If nobody smoked, 1 out of 3 cancer related deaths wouldn’t exist *According to CDC

5. Secondhand Smoke Secondhand smoke contains about 70 cancer-causing chemicals Secondhand smoke causes an estimated 46,000 premature deaths from heart disease each year in the United States among nonsmokers. Nonsmokers who are exposed to secondhand smoke at home or at work increase their risk of developing lung cancer by 20–30%

6. Tobacco users develop an addiction due to nicotine, a substance found in the leaves of tobacco Nicotine is a stimulant, it increases the action of the central nervous system Two pronged sword Raises blood pressure and increases heart rate Smoking damages blood vessels by: Vessels grow thicker and grow narrower Which makes heart rate increase and blood pressure increase Once addicted, people need to increase consumption to satisfy cravings

7. How does body become addicted to nicotine? Nicotine increases activity in the brain and CNS When it enters the brain, dopamine gets released...the “feel good” chemical that causes feelings of calm and pleasure Also helps you to feel alert Over time the brain adjusts to this “buzzed” feeling and more nicotine is required to achieve the same buzz Eventually, the user will need more amounts of nicotine to feel normal

8.

12. Hookah vs. Cigarettes A typical 1-hour-long hookah smoking session involves inhaling 100–200 times the volume of smoke inhaled from a single cigarette The charcoal used to heat tobacco in the hookah increases the health risks by producing high levels of carbon monoxide, metals, and cancer-causing chemicals. Water pipe smoking is at least as addictive as cigarettes Secondhand smoke from hookahs poses a serious risk for nonsmokers, particularly because it contains smoke not only from the tobacco but also from the heat source (charcoal) used in the hookah Hookah smokers are at risk for the same kinds of diseases as are caused by cigarette smoking, including oral cancer, lung cancer, stomach cancer, cancer of the esophagus, reduced lung function, and decreased fertility
