The Facts About Cigarette Smoking

Nearly 50 million Americans smoke, resulting in nearly 450,000 deaths each year. The smoke from cigarettes alone contains over 4,000 different chemicals, including 200 known poisons. Cigarettes are also highly addictive; one-third of the young people who "experiment" end up addicted by the time they turn 20.

Even though many people smoke because they believe cigarettes calm their nerves, smoking releases epinephrine, a hormone that creates physiological stress in the smoker, rather than relaxation. Not only are smokers affected by their habit, but second-hand smoke is also responsible for approximately 3,000 lung cancer deaths annually of non-smokers in the United States.

There are numerous negative side effects associated with smoking cigarettes; they include the loss of the sense of smell and taste, emphysema, premature and overabundant face wrinkles, gastric ulcers, smoker's cough, stroke, heart disease, and cancer of the mouth, larynx, pharynx, esophagus, lungs, pancreas, cervix, uterus, and bladder.

Smokers become physically and psychologically dependent, suffering numerous withdrawal symptoms when they attempt to quit. These symptoms include: changes in body temperature, heart rate, digestion, muscle tone, and appetite, irritability, anxiety, sleep disturbances, nervousness, headaches, fatigue, nausea, and cravings for tobacco that can last days, weeks, months, years, or even an entire lifetime.

Cigarette smoking is perhaps the most devastating preventable cause of disease and premature death. Adolescent cigarette smokers are more likely to smoke marijuana and are more likely to use other illicit drugs such as cocaine and heroin in the future.
