• Rapidly progressive bilateral pulmonary infiltrates occurred in a 19-year-old man following an unusual hydrocarbon abuse. The acute illness was the result of a "trick" known as "fire-breathing." Fire-breathing involves filling the oral cavity with butane gas, from an ordinary butane cigarette/cigar lighter, and exhalation of the volatile vapors over an open flame producing a flame-throwing effect. Because of the pulmonary toxic reaction, this activity could have a serious or even fatal outcome.
