Abstract
Recreational cocaine abuse via intranasal "snorting," "free-base" smoking, "body-packing," or intravenous injection can be lethal. Increasing illicit use of cocaine hydrochloride and the misuse of legal over-the-counter (OTC) nasal drugs are known causative agents of nasal septal perforation with loss of taste and smell. Although 2 to 3 mg/kg is the recommended maximum dose for topical anesthesia, cocaine snorters may use 1,000 mg or more daily on a "run." Furthermore, the newer route of smoking the extracted volatile "free-base" form of the adulterated street drug provides a plasma concentration producing the same physiological and subjective effects of intravenous cocaine. Presented are two cases exemplifying unusual complications of cocaine abuse: 1. total nasal septal bony and cartilaginous necrosis with resultant saddle-nose deformity and osteolytic sinusitis secondary to chronic intranasal "snorting" and 2. tracheobronchial rupture with pneumomediastinum secondary to smoking "free-base" cocaine.
