Smoker's lungs and emphysema. Illustration based on a 3D computed tomography (CT) scan of the lungs of a smoker who has developed emphysema. Cigarettes contain cancer-causing chemicals and the addictive drug nicotine. Tobacco smoke is the major cause of lung cancer and several other lung diseases such as emphysema, a disorder where the air sacs in the lungs become enlarged and damaged reducing the surface area for the exchange of oxygen and carbon dioxide. | |
