Betel nut chewing, also called betel quid chewing or areca nut chewing, is a practice in which areca nuts (also called "betel nuts") are chewed together with slaked lime and betel leaves for their stimulant and narcotic effects, the primary psychoactive compound being arecoline. The practice is widespread in Southeast Asia, Micronesia, Island Melanesia, and South Asia. It is also found among both Han Chinese immigrants and indigenous peoples of Taiwan, Madagascar, and parts of southern China. It was introduced to the Caribbean in colonial times.
