Discussion: Methamphetamine is recognized as the most common illegal stimulant in the United States today, where its use has reached epidemic proportions. A myriad of negative health affects have been reported, but direct pulmonary toxicity has rarely been described in the literature. A single animal study demonstrated bronchoalveolar lavage fluid evidence of acute lung injury, a precursor to fibrosis, in mice exposed to inhaled methamphetamine1. A single case report described progressive pulmonary fibrosis in a chronic user of methamphetamine secondary to associated talc inhalation, which is often used as a “filler” material when methamphetamine is “cut”, or mixed2.
Conclusions: Pulmonary fibrosis is a rare complication of inhaled methamphetamine use. As the methamphetamine epidemic continues, this will likely become a more common etiology of interstitial lung disease. A detailed exposure history, which may be difficult to obtain because of the associated social stigma, is of paramount importance in identifying this risk factor.
