Spontaneous secondary pneumothorax due to cannabis-induced bullous lung disease: a case report.

Abstract

The authors describe a case of an adult male with a past medical history of spontaneous pneumothorax and long-standing marijuana use presenting with dyspnoea who was found to have a secondary spontaneous pneumothorax requiring invasive treatment. The aetiology of lung injury due to heavy marijuana smoke may be from direct tissue injury from inhaled irritants and the method of which marijuana smoke is inhaled compared with tobacco smoke. Chronic marijuana use should be considered when evaluating structural lung disease and pneumothorax in the setting of minimal tobacco use.
