Inhalation injury after capsaicin exposure.

Pepper spray is defined as a non-lethal agent used in riot control and personal self-defense. Oleoresin capsicum (OC), derived from the fruit of plants in the Capsicum genus, commonly referred to as hot peppers or chilies, is the active agent used in many of these defense sprays. Although generally assumed to be safe and effective, the consequences of OC cannot be predicted with certainty.
