RESUMEN

We present the case of a 33-year-old white male truck driver with a ten-year history of 3.5-g/wk "crank" and "peanut butter methamphetamine" inhalation (methamphetamine and propylhexedrine, respectively). This patient developed marked pulmonary hypertension as a probable consequence of abuse of these drugs. Proposed mechanisms of disease invoke toxic endothelial injury, hypoxic insult, direct spasm, vasculitis, and dysregulation of mediators of vascular tone. The possible role of genetics is discussed in reference to variability of human response to sympathomimetic challenge.
