Presentation Transcript

  1. Nicotine • The average cigarette contains from 1 to 16 grams of nicotine.  When inhaled, nicotine enters the bloodstream, reaching the brain in less than 10 seconds.  In less than a minute, nicotine spreads throughout the entire body. • Since nicotine is a stimulate, it raised blood pressure and increases the heart rate,

  2. Poisonous Substances in Tobacco SmokeTar & Carbon Monoxide • Tobacco is an addictive and toxic drug. It’s a carcinogen. Tobacco Smoke contains Tar and Carbon Monoxide.

  3. TAR • The tar damages a smoker’s respiratory system by paralyzing and destroying cilia. • Tar destroys the alveoli which absorbs oxygen and rids the body of carbon dioxide. Smokers are susceptible to bronchitis, pneumonia, emphysema, heart disease, and cancer.

  4. Carbon Monoxide • Its is absorbed more easily than oxygen. • It increases the risk of high blood pressure, hardening of the arteries, and other circulatory problems.

  5. Smokeless Tobacco Pipes, Cigars, Dip, and Chew. • Cigars contain significantly more nicotine and produce more tar and carbon monoxide than cigarettes (20 cigarettes). • Cancer of the lips, mouth, throat, larynx, and esophagus are at a huge risk with smokeless tobacco.

  6. Smokeless Tobacco • The harmful effects of smokeless tobacco are absorbed into the body at levels up to three times the amount of a single cigarette ( 2 packs of cigarettes) • Irritates the sensitive tissue of the mouth causing leukoplakia.

  7. Short –Term Effects • Brain Chemistry Changes • Heart Rate Increases • Taste buds are dulled • Appetite is reduced • Bad breath • Yellowed teeth/nails • Smelly Hair

  8. Long-Term Effects • Chronic Bronchitis • Coronary Heart Disease • Stroke • Weakened Immune System • Emphysema • Lung Cancer • Stoma

  9. Secondhand Smoke • The health effects of tobacco smoke affect smokers and nonsmokers alike. Nonsmokers who breathe air containing tobacco smoke are also at high risk for health problems. • Environmental smoke (ETS)-secondhand smoke is air that has been contaminated by tobacco smoke. • ETS is composed of mainstream smoke and sidestream smoke.

  10. Mainstream smoke: exhaled from the lungs of a smoker Sidestream smoke: The smoke from the burning end of a cigarette, pipe, or cigar.

  11. Mainstream smoke contains lower concentration of carcinogens, nicotine, and tar. For this reason, sidestream smoke is more dangerous than mainstream smoke. • ETS contains more than 4,000 chemical compounds and more than 50 are cancer-causing carcinogens.
