Tobacco is a plant grown for its leaves, which are smoked, chewed, or sniffed for a variety of effects.
- It is considered an addictive substance because it contains the chemical nicotine.
- Tobacco also contains more than 19 known cancer-causing chemicals (most are collectively known as "tar") and more than 4,000 other chemicals.
Most smokers in the United States would like to quit smoking. Most people who have quit smoking made at least one unsuccessful quit attempt in the past. Try not to view past attempts to quit as failures, but rather as learning experiences.
HEALTH RISKS OF SMOKING OR SMOKELESS TOBACCO
Many smokers come to depend on the positive effects of nicotine, such as boosting their mood, improving short-term memory and concentration, and producing a sense of well-being.
There are many more reasons to quit using tobacco. Knowing the serious health risks may help motivate you to quit. When used over a long period, tobacco and related chemicals such as tar and nicotine can increase your risk of many health problems.
- Heart and blood vessel problems:
Blood clots and aneurysms in the brain, which can lead to strokes
- Blood clots in the legs, which may travel to the lungs
Coronary artery disease, including angina and heart attacks
High blood pressure
- Poor blood supply to the legs
- Problems with erections because of decreased blood flow into the penis
- Cancer (especially in the lung, mouth, larynx, esophagus, bladder, kidney, pancreas, and cervix)
- Poor wound healing, especially after surgery
- Lung problems such as emphysema and chronic bronchitis, or asthma that is harder to control
- Problems during pregnancy, such as babies born at low birth weight, premature labor, miscarriage, and cleft lip
- Other health risks or problems:
- Decreased ability to taste and smell
- Harm to sperm, which contributes to infertility
- Loss of sight due to an increased risk of macular degeneration
- Tooth and gum diseases
- Wrinkling of the skin
Smokers who switch to smokeless tobacco instead of quitting tobacco completely still carry a number of health risks:
- Increased risk of mouth or nasal cancer
- Gum problems, tooth wear, and cavities
- Worsening high blood pressure and angina
HEALTH RISKS OF SECONDHAND SMOKE
Those who are regularly around the smoke of others (secondhand smoke) have a higher risk of:
- Heart attacks and heart disease
- Sudden and severe reactions, including those involving the eye, nose, throat, and lower respiratory tract
Infants and children who are regularly exposed to secondhand smoke are at risk of:
- Asthma (children with asthma who live with a smoker are much more likely to visit the emergency room)
- Infections, including virus-caused upper respiratory infections, ear infections, and pneumonia
- Lung damage (poor lung function)
- Sudden infant death syndrome (SIDS)
