The effects on smoking on lung tissue . Computer illustration of the organs of the thoracic cavity, with the lung on the left pink and healthy, and the lung on the right affected by smoking. Cigarettes contain cancer-causing chemicals and the addictive drug nicotine. Tar from tobacco smoke builds up in the lungs causing long-term damage. 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.
