Let's Stop Smoking

Pulmonary Effects of Tobacco Smoking

This site is especially for teenagers who smoke. It contains images of normal lungs and of lungs damaged by diseases caused by cigarette smoking. While young smokers may have heard many verbal descriptions of the damaging effects of cigarette smoke, seeing the actual changes that can occur may motivate them to quit smoking or to stop others from beginning to smoke. One should not forget, as well, that cigarette smoking also has harmful effects, which are not illustrated here, on organs other than the lungs.

Introduction: This presentation will describe some aspects of the normal lung and then illustrate changes that occur in persons with chronic obstructive pulmonary disease (emphysema and chronic bronchitis) and lung cancer. These diseases are common occurrences in cigarette smokers. For each of the diseases, a case history will be given, followed by a description of the changes in the lung.
