Cigars, smokeless tobacco, clove cigarettes and low-tar and low-nicotine cigarettes all pose the risks that are usually associated only with cigarette smoking. Tobacco effects not only the smoker, but anyone in the smoker's environment. There are three main risks associated with any tobacco use:
I. Adverse Health Affects
II. Addiction
III. Adoption of other risky behaviors
I. Adverse Health Affects
Heart Disease
Many factors influence a person's chances of developing heart disease [coronary artery disease]. The risk factors beyond individual control include family history, gender and age. However, individuals are able to modify the risk factors of high blood pressure, elevated cholesterol levels, sedentary lifestyle, fatty diet and obesity, as well as smoking. Compared to non-smokers, smokers have a 70 percent greater death rate from heart disease; they are also four times more likely to develop symptoms of heart disease. Every year that passes reduces the chance of heart disease for smokers who have quit.Lung Cancer
Emphysema
Cigarette smoking is the major cause of lung cancer. Risk for lung cancer increases with the amount of cigarettes smoked: one pack-a-day smokers may have a seven to ten times greater risk, while two pack-a-day smokers may have a fifteen to twenty-five times greater risk. Fewer than 10 percent of lung cancers occur among non-smokers, and new studies indicate that many of these persons were exposed to significant amounts of secondhand or sidestream smoke. Cancers of the lip, tongue, salivary glands and esophagus are five times more common in smokers. Kidney, bladder, pancreatic and larynx cancers are also more likely among those who smoke.
Emphysema is known as a chronic obstructive pulmonary disease [COPD] or chronic obstructive lung disease [COLD]. Over time [only a few years for some], chemicals from smoking cause the tiny air sacs, alveoli, to weaken and sometimes rupture. The result is pronounced breathing impairment, particularly the ability to exhale. People with emphysema often are unable to blow out a single match. Emphysema is usually preceded by chronic bronchitis-another COPD. Quitting smoking will greatly slow the rate of decline; however, damaged lung tissue is unable to repair itself. Both lung cancer and emphysema result in the lungs losing their spongy, elastic properties, which enable them to function efficiently.
II. Addiction
III. Adoption of other risky behaviors
Tobacco is considered to be a "gateway drug", leading to the use of other serious drugs including alcohol. It is often the first drug used by young people who later use alcohol, marijuana and other drugs.
