ECMO-dependent respiratory failure after snorting speed associated with anti-GBM antibodies.

A previously well 20-year-old man with a history of nasal inhalation of "speed" was retrieved on extracorporeal membrane oxygenation for respiratory failure. Anti-glomerular basement membrane (anti-GBM) antibody was positive in the absence of renal disease. We postulate a hitherto unreported causal link between snorting "speed" and lung disease associated with anti-GBM antibody formation.
