Pepper spray contains capsaicin, derived from chili peppers, and is a non-lethal substance used mainly by law enforcement officials in riot control and for subduing multiple criminals. Some individuals also carry small canisters of pepper spray for self-defense purposes. Citizens can purchase pepper spray to protect them against possible criminal attack or encounters with vicious animals such as dogs or bears.
