1.  Tobacco smoke is harmful to smokers and nonsmokers. Cigarette smoking causes many types of cancer, including cancers of the lung, esophagus, larynx (voice box), mouth, throat, kidney, bladder, pancreas, stomach, and cervix, as well as acute myeloid leukemia. Smoking reduces your lungs' ability to remove germs, dirt and the chemicals you expose yourself to when you smoke. The chemicals that cause cancer get trapped.  The alveoli absorb the oxygen you breathe in and then get rid of the carbon dioxide as you exhale. When the alveoli become damaged, your lungs and heart must work harder to take in oxygen and release carbon dioxide, which leads to chronic lung disease.

    In addition to raising the risk of cancer, smoking also reduced the ability of the lungs to function. In particular, smoking reduces the vital capacity of the lungs, which is the amount of air the lungs can take in. This reduction in vital capacity has several important health effects.
