Breath-holding in a marijuana smoker

It is vital to ask about illicit drug smoking in the respiratory history as marijuana smoking augments the detrimental effects of tobacco. We describe the case of a 28 year old marijuana smoker who developed a pneumothorax during a breath-holding competition. Pneumothorax is a common clinical entity that every physician should be aware of how to manage and lifetime risk is considerably increased by smoking and in exposure to barotrauma.
