Emphysema
One of the main causes of emphysema is smoking cigarettes. There are many other effects on respiratory health caused by a cigarette addiction but emphysema is the end result of all damage to the lungs caused by the inhalation of the cigarette tar, and other chemicals in cigarettes. It is the cumulative effects of cigarette smoking over a long time period that cause emphysema so the condition is often seen in older adults.
