Dangers of using cigars or pipes: • Cigar smoke contains 25 times more carbon monoxide and up to 400 times more nicotine than cigarette smoke. • Cigar and pipe smokers are more likely to develop cancers of the lip, mouth, and tongue than nonsmokers.
Tobacco Addiction Nicotine: type of drug = stimulant is as addictive or more so a drug as cocaine or heroin. Nicotine addiction leads to more diseases and deaths than all other addictions combined. Reducing or cutting off the supply of nicotine causes withdrawal.
Psychological Dependence A tobacco user first becomes psychologically dependent on tobacco. Psychological dependence leads to addiction because a person believes that he or she needs a drug in order to feel good or function normally although they really do not To break a psychological dependence on tobacco, users need to change their habits.
Physical Dependence Physical dependence is an addiction in which the body develops a chemical need for a drug. Physical dependence on tobacco is directly related to nicotine. As a person continues to use tobacco, the body’s tolerance for nicotine increases. Tolerance is the body’s need for larger and larger doses of a drug to produce the same effect.

Respiratory System Tobacco smoke damages the alveoli. This damage may lead to emphysema. Smokers are also between 12 and 22 times more likely than nonsmokers to develop lung cancer. Some long term effects of smoking include……………… Digestive System increase the risk of cavities and gum disease. Taste Buds die. linked to cancers of the mouth, throat, esophagus, stomach, and pancreas. Circulatory System Tobacco use is linked to heart disease. Excretory System Smokers have at least twice the risk of developing bladder cancer as nonsmokers. Smokeless tobacco can also put users at risk of developing bladder cancer. Nervous System Tobacco use reduces the flow of oxygen to the brain, which can lead to a stroke.
Smoking is the #1 risk factor associated with Heart Attacks and Heart Disease
Common Problems of the Respiratory System associated with smoking Disease or Disorder Description Treatment is a chronic inflammation of the bronchi (medium-size airways) in the lungs. Chronic Bronchitis Bronchodilators Disease in which alveoli harden and disintegrate; symptoms include extreme difficulty breathing; almost entirely caused by smoking No known cure; pure oxygen can make breathing easier Emphysema Uncontrolled growth of cells that produce abnormally in lungs; often caused by smoking Surgery, radiation, and medication; Survival rates are very low Lung Cancer
How Tobacco Affects Nonsmokers (cont’d.) Exposure to secondhand smoke causes people to become passive smokers. Passive smoking is harmful because: • It can cause respiratory problems, including lung cancer, just like smoking. • It may irritate the nose and throat and cause itchy and watery eyes, headaches, and coughing.
