Smoking—A Threat to Health
Smoking and health
Smoking causes many health problems. It affects many parts of the body, not just the lungs.
The more cigarettes you smoke each day, the greater your risk of disease. Smokers tend to die
earlier than nonsmokers.
Smoking and cancer
Smoking can lead to cancers of the:




Mouth and lip.
Throat and windpipe.
Kidney and bladder.
Pancreas and stomach.
Smoking is the main cause of lung cancer. The more you smoke each day, the higher your
chances of getting lung cancer. You are also at higher risk if you started smoking in your teens.
Smoking and lung disease
Chronic obstructive pulmonary disease (COPD) is a serious lung disease that makes it hard to
breathe. It also makes your heart have to work harder. COPD symptoms get worse over time
and never go away. There is no cure for COPD.
Smoking and heart disease
The more you smoke, the greater your chances of heart disease. Smoking narrows the blood
vessels that carry blood to your heart muscle. They are more likely to get blocked and cause
heart disease.
Smoking and stroke
Smoking also narrows the blood vessels that carry blood to your brain. A stroke happens when
the blood supply to part of the brain is cut off. Strokes often cause death. Even if the stroke is
not fatal, you may have trouble eating, talking, and taking care of yourself.
Smoking and other health problems
Smoking can make sleep problems worse. Smokers also tend to get colds and lung infections
more often.

Smoking can narrow blood vessels in your legs. When this happens, you may have pain when
you walk. It could cause sores on your skin and tissue death. Sometimes the foot or leg has to
be removed.
Smoking also raises your blood pressure. This can damage your kidneys. High blood pressure
also puts you at risk for a heart attack or stroke.
Smoking can also slow healing and cause other problems if you need to have surgery.
Smoking and pregnancy




You have a greater risk of losing your baby during pregnancy.
Your baby may have a low birth weight.
Your baby may have trouble breathing at birth.
Smoking and nonsmokers
Nonsmokers can be hurt by breathing in your smoke. Every time you smoke, poisonous
chemicals go into the air. Each year, many nonsmokers die from lung cancer because they
breathed secondhand smoke.
Quitting Smoking
If you stop smoking, many of these risks decrease. You can quit, no matter what your age.
When you quit, your body can start to get better. Talk to your healthcare provider about ways to
help you quit.
