CANCER The Centers for Disease Control and Prevention says cigarette smoking is responsible for 151,322 cancer deaths annually in the United States. Most of those--116,920--are from lung cancer. The CDC says men who smoke are 22 times more likely to die from lung cancer than non-smokers. Women who smoke are 12 times more likely to die from the disease.

Smoking also has been linked time and again to cardiovascular diseases. Among these, the biggest killer is heart disease: according to the CDC, smoking triples the risk of dying from heart disease among middle-aged men and women. Studies also show an increased risk of death from stroke, aneurysms, high blood pressure, and other cardiovascular illnesses.

OTHER ILLNESSES A report recently published in the American Journal of Epidemiology suggested that smoking increased the risk of developing non- insulin-dependent diabetes mellitus (NIDDM) by more than three times. Studies have pointed to smoking as a risk in vision loss among older people, mental impairment later in life, Alzheimer's disease and other forms of dementia.

Pregnant women who smoke can pass nicotine and carbon monoxide to their baby through the placenta. Research indicates this can prevent the baby from getting the oxygen and nutrients it needs to grow--potentially leading to fetal injury, premature birth, or low birth weight. According to the American Lung Association, smoking during pregnancy accounts for an estimated 20 to 30 percent of low birthweight babies, up to 14 percent of premature deliveries, and about 10 percent of all infant deaths.
