Ghost peppers are used as a food and a spice. It is used in both fresh and dried forms to "heat up" curries, pickles. It is popularly used in combination with beef or fermented fish. In northeastern India, the peppers are smeared on fences or incorporated in smoke bombs as a safety precaution to keep wild elephants at a distance. The pepper's intense heat makes it a fixture in competitive chili-pepper eating. In 2009, scientists at India's Defence Research and Development Organisation (DRDO) announced plans to use the peppers in hand grenades as a nonlethal method to control rioters with pepper sprays or in self-defence.The DRDO said that ghost pepper-based aerosol sprays could be used as a "safety device", and "civil variants" of chili grenades could be used to control and disperse mobs. Chili grenades made from ghost peppers were successfully used by the Indian Army in August 2015 to flush out a terrorist hiding in a cave.
