Tobacco and Smoking

John Dorrance

Tobacco Basics

Definition of Tobacco: dried leaves processed for smoking: the dried leaves of a plant of the nightshade family, processed primarily for smoking in cigarettes, cigars, and pipes.  They usually Smoke it but they may also eat it and snort it.



Ingredients of Cigarettes

Cigarette smoke contains over 4,000 chemicals, including 43 known cancer-causing (carcinogenic) compounds and 400 other toxins. These include nicotine, tar, and carbon monoxide, as well as formaldehyde, ammonia, hydrogen cyanide, arsenic, and DDT.

Nicotine is highly addictive. Smoke containing nicotine is inhaled into the lungs, and the nicotine reaches your brain in just six seconds.

While not as serious as heroin addiction, addiction to nicotine also poses very serious health risks in the long run.


About 3800 people start smoking everyday.

Cancer is caused by changes in a cell's DNA – its genetic "blueprint." Some of these changes may be inherited from our parents, while others may be caused by outside exposures, which are often referred to as environmental factors. Environmental factors can include a wide range of exposures, such as:

•Lifestyle factors (nutrition, tobacco use, physical activity, etc.)

•Naturally occurring exposures (ultraviolet light, radon gas, infectious agents, etc.)

•Medical treatments (chemotherapy, radiation, immune system-suppressing drugs, etc.)

•Workplace exposures

•Household exposures

Effects of Smoking

As a smoker, you’re at risk for cancer of the mouth. Tobacco smoke can also cause gum disease, tooth decay and bad breath. The teeth become unsightly and yellow. Smokers may experience frequent headaches. And lack of oxygen and narrowed blood vessels to the brain can lead to strokes.   Lungs and Bronchi Moving down to your chest, smoke passes through the bronchi, or breathing tubes. Hydrogen cyanide and other chemicals in the smoke attack the lining of the bronchi, inflaming them and causing that chronic smoker’s cough. Because the bronchi are weakened, you’re more likely to get bronchial infections. Mucus secretion in your lungs is impaired, also leading to chronic coughing. Smokers are 10 times as likely to get lung cancer and emphysema as nonsmokers.   Smoking and the Heart The effects of smoking on your heart are devastating. Nicotine raises blood pressure and makes the blood clot more easily. Carbon monoxide robs the blood of oxygen and leads to the development of cholesterol deposits on the artery walls. All of these effects add up to an increased risk of heart attack. In addition, the poor circulation resulting from cholesterol deposits can cause strokes, loss of circulation in fingers and toes and impotence.   Smoking and the Body’s Organs The digestive system is also affected. The tars in smoke can trigger cancer of the esophagus and throat. Smoking causes increased stomach acid secretion, leading to heartburn and ulcers. Smokers have higher rates of deadly pancreatic cancer. Many of the carcinogens from cigarettes are excreted in the urine where their presence can cause bladder cancer, which is often fatal. High blood pressure from smoking can damage the kidneys.
