People who smoke “crack” cocaine can significantly elevate their risks for a form of emphysema called bullous emphysema, which occurs when multiple alveoli collapse and form larger sacs, known as bullae, that don’t contribute to proper oxygen/carbon dioxide exchange within the lungs.

In others, it comes from structural changes that reduce the body’s ability to mechanically expel infectious microorganisms. Alcohol abuse and alcoholism also increase the chances for development of a specific form of pneumonia, called aspiration pneumonia, associated with the inhalation of foreign material into the lungs.   Continue reading
