In addition to the risk of miscarriage, premature birth, and death of the baby in its first year of life, a woman's smoking during pregnancy also has other effects on the baby:
- The growth and development of all unborn babies is impaired if their mothers smoke. On average, birth weight is reduced by about half a pound. This makes little difference to a baby of normal weight, but could be crucial to ones weighing 3 to 4 pounds.
- The development of the brain is also affected. Children whose mothers smoked during pregnancy are on average about one year behind non-exposed children in reading and numerical ability, for example. Loss of a few IQ points may be hardly noticeable to a normally intelligent child or adult, but may be critical for someone on the borderline.
- The child will be more likely to have behavioral problems and hyperactivity.
- Finally, during the first few years of life, children are especially vulnerable to the harmful effects of
passive smokingif their parents smoke. These effects include worsening of asthma, increased frequency of colds and ear infections, and increased risk of sudden infant death syndrome.
Smoking causes many premature deaths from diseases that are largely incurable, but preventable by stopping smoking. There are three main killing diseases which smoking causes or brings on earlier:
- Heart disease. Smoking is responsible for 30 percent of all heart attacks and cardiovascular deaths.
- Cancer. It is responsible for at least 30 percent of all cancer deaths and 87 percent of lung cancer deaths each year.
- Lung problems. Smoking is responsible for 82 percent of deaths due to emphysema and chronic bronchitis.
Smoking also exacerbates diseases and conditions that are not always fatal, but cause suffering or are sources of personal concern.
- Smoking delays healing of peptic ulcers of the stomach and duodenum, many of which would heal spontaneously in non-smokers.
- Its effects on blood vessels cause chronic pains in the legs (claudication) which can progress to gangrene and amputations of the toes or feet.
- An effect on elastic tissue causes wrinkling of the skin of the face to develop earlier in chronic smokers. On average they look 5 years older than non-smokers of the same age do.
- Smoking also brings on an earlier menopause in women, advancing it by an average of 5 years.
- It reduces women's fertility and delays conception after they stop using oral contraceptives.
- It impairs erections in middle-aged and older men and may affect the quality of their sperm. It seems to "sedate" sperm and to impair their motility. This is reversed after stopping smoking.
- Smoking accelerates the rate of
osteoporosis, a disease which causes bones to weaken and fracture more easily.
- Women who smoke during pregnancy damage their unborn child, causing effects that last throughout the child's life. The risks of miscarriage, premature birth, and death of the baby in its first year of life are all significantly increased.

Certain chemicals and other substances
Some viruses and bacteria
Family history of cancer
Poor diet, lack of physical activity, or being overweight
Many of these risk factors can be avoided. Others, such as family history, cannot be avoided. People can help protect themselves by staying away from known risk factors whenever possible.
If you think you may be at risk for cancer, you should discuss this concern with your doctor. You may want to ask about reducing your risk and about a schedule for checkups.
Over time, several factors may act together to cause normal cells to become cancerous. When thinking about your risk of getting cancer, these are some things to keep in mind:
Not everything causes cancer.
Cancer is not caused by an injury, such as a bump or bruise.
Cancer is not contagious. Although being infected with certain viruses or bacteria may increase the risk of some types of cancer, no one can "catch" cancer from another person.
Having one or more risk factors does not mean that you will get cancer. Most people who have risk factors never develop cancer.
Some people are more sensitive than others to the known risk factors.
The sections below have more detailed information about the most common risk factors for cancer. You also may want to read the NCI booklet Cancer and the Environment.
Growing OlderThe most important risk factor for cancer is growing older. Most cancers occur in people over the age of 65. But people of all ages, including children, can get cancer, too.
Tobacco use is the most preventable cause of death. Each year, more than 180,000 Americans die from cancer that is related to tobacco use.
Using tobacco products or regularly being around tobacco smoke (environmental or secondhand smoke) increases the risk of cancer.
Smokers are more likely than nonsmokers to develop cancer of the lung, larynx (voice box), mouth, esophagus, bladder, kidney, throat, stomach, pancreas, or cervix. They also are more likely to develop acute myeloid leukemia (cancer that starts in blood cells).
People who use smokeless tobacco (snuff or chewing tobacco) are at increased risk of cancer of the mouth.

- Cigarette smoking remains the leading preventable cause of death in the United States, causing an estimated 438,000 deaths - or about 1 out of every 5 - each year.
- In the United States, approximately 38,000 deaths each year are caused by exposure to secondhand smoke.
- Lung cancer is the leading cause of cancer death among both men and women in the United States, with 90 percent of lung cancer deaths among men and approximately 80 percent of lung cancer deaths among women attributed to smoking.
- Smoking also increases the risk of many other types of cancer, including cancers of the throat, mouth, pancreas, kidney, bladder, and cervix.
- People who smoke are up to six times more likely to suffer a heart attack than nonsmokers, and the risk increases with the number of cigarettes smoked. Smoking also causes most cases of chronic obstructive lung disease, which includes bronchitis and emphysema.
- In 2007, approximately 19.8 percent of U.S. adults were cigarette smokers.
- Twenty-three percent of high school students and 8 percent of middle school students in this country are current cigarette smokers.(See Tobacco Statistics Snapshot for references for this information.)
