Smoking harms nearly every organ of the body, causing many diseases and affecting the health of smokers in general. Quitting smoking has immediate as well as long-term benefits for you and your loved ones.
Smoking can cause cancer and then block your body from fighting it. Poisons in cigarette smoke can weaken the body’s immune system, making it harder to kill cancer cells. When this happens, cancer cells keep growing without being stopped. Poisons in tobacco smoke can damage or change a cell’s DNA. DNA is the cell’s “instruction manual” that controls a cell’s normal growth and function. When DNA is damaged, a cell can begin growing out of control and create a cancer tumor.
Doctors have known for years that smoking causes most lung cancers. It’s still true today, when nearly nine out of ten lung cancers are caused by smoking cigarettes. In fact, smokers have a greater risk for lung cancer today than they did in 1964, even though they smoke fewer cigarettes. One reason may be changes in how cigarettes are made and what chemicals they contain. The number of individuals needed to receive tobacco cessation counseling and save one life, is approximately 50 individuals.
Treatments are getting better for lung cancer, but it still kills more men and women than any other type of cancer. In the United States, more than 7,300 nonsmokers die each year from lung cancer caused by secondhand smoke. Secondhand smoke is the combination of smoke from the burning end of a cigarette and the smoke breathed out by smokers.
Smoking can cause cancer almost anywhere in your body, including the:
The chemicals in tobacco smoke harm your blood cells. They also can damage the function of your heart and the structure and function of your blood vessels.
Smoking is a major risk factor for heart disease. When combined with other risk factors—such as unhealthy blood cholesterol levels, high blood pressure, and overweight or obesity—smoking further raises the risk of heart disease.
The effects of your smoking on other household members through the effects of second hand smoke are important reasons to quit. Secondhand smoke is the combination of smoke from the burning end of a cigarette and the smoke breathed out by smokers. Secondhand smoke contains more than 7,000 chemicals. Hundreds are toxic and about 70 can cause cancer.
Since the 1964 Surgeon General’s Report, 2.5 million adults who were nonsmokers died because they breathed secondhand smoke.
Adults Who Smoke
The experts found that behavioral interventions and medications, including nicotine replacement therapy (NRT)—either alone or in combination—greatly improve the chances that a person will be able to successfully quit. They also found that the harms of behavioral interventions are likely to be small to none, and the potential harms of medications and NRT are likely to be small.
Pregnant Women Who Smoke
The experts found that behavioral interventions greatly improve the chances that a pregnant woman can stop smoking during her pregnancy. Additionally, not smoking during pregnancy reduces the risk of a baby being born too small or too early.
There were not enough studies for the Task Force to weigh the overall benefits and harms of using medications, including NRT, to help pregnant women quit smoking.
Finally, the Task Force found that there was not enough information to determine whether e-cigarettes are more helpful or harmful for smoking cessation for adults and pregnant women.
