A tranquillizer gun, capture gun or dart gun, is a non-lethal air gun often used for incapacitating animal targets via anesthetic drugs usually referred as tranquilizers. These guns shoot darts with a hypodermic needle tip, filled with a dose of tranquilizer solution that is either sedative, comatosing or paralytic, which is injected into the target upon impact and will temporarily impair the target's physical function to a level that allows it to be approached and handled in an unresisting and thus safe manner. Tranquillizer guns have a long history of use to stun wildlife and criminals when they are in a place where they pose a threat to others and themselves without having to kill the animal or individual, or used to capture wildlife risking serious injuries to both the hunter and the target. They are also used for recreation. Tranquillizer darts can also be fired by crossbow or breath-powered blowgun.
