Healthy Lung vs. Diseased Lung

Watch this video as Beth Turner, CHES, Manager of Tobacco Control with the American Lung Association describes the differences between a pair of healthy lungs and a pair of diseased lungs. The diseased lungs represent the damage caused from smoking roughly 1 pack of cigarettes per day for 20 years.

Did you know?

    • The diseased lungs are an example of the damage caused by cigarette smoke. Cigarette smoke contains over 7,000 toxic chemicals, and about 70 have been known to cause cancer.*
    • The diseased lungs will only partially inflate due to the extensive damage to the airways and lobes. This is often what happens when smokers develop emphysema.*
    • Good news! Smokers’ lungs do have the ability to repair themselves if they quit smoking. On average, smokers’ lungs can heal themselves back to a healthy state after 10-15 years.*
