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.[1][2]

The preparation combining the areca nut, slaked lime, and betel (Piper betle) leaves is known as a betel quid (also called paan or pan in South Asia), but the exact composition of the mixture varies geographically.[3] It can sometimes include other substances for flavoring and to freshen the breath, like coconut, dates, sugar, menthol, saffron, cloves, aniseed, cardamom, and many others. The areca nut can be replaced with tobacco or the two chewed together, and the betel leaves can be excluded. In West Papua, the leaf may be replaced with stem and inflorescence of the Piper betle plant.[4] The preparation is not swallowed but is spat out after chewing. Chewing results in permanent red stains on the teeth after prolonged use. The spit from chewing betel nuts, which also results in red stains, is often regarded as unhygienic and an eyesore in public facilities in certain countries.[1][5][6]

Betel nut chewing is addictive and causes adverse health effects, mainly oral and esophageal cancers, and cardiovascular disease.[6][1] When chewed with additional tobacco in its preparation (like in gutka), there is an even higher risk, especially for oral and oropharyngeal cancers.[7] With tobacco it also raises the risk of fatal coronary artery disease, fatal stroke,[8][9] and adverse reproductive effects including stillbirth, premature birth and low birth weight.[10]

The practice of betel nut chewing originates from Southeast Asia where the plant ingredients are native. The oldest evidence of betel nut chewing is found in a burial pit in the Duyong Cave site of the Philippines, an area where areca palms were native, dated to around 4,630±250 BP. Its diffusion is closely tied to the Neolithic expansion of the Austronesian peoples. It was spread to the Indo-Pacific during prehistoric times, reaching Micronesia at 3,500 to 3,000 BP, Near Oceania at 3,400 to 3,000 BP; South India and Sri Lanka by 3,500 BP; Mainland Southeast Asia by 3,000 to 2,500 BP; Northern India by 1500 BP; and Madagascar by 600 BP. From India it spread westwards to Persia and the Mediterranean. It was present in the Lapita culture, based on archaeological remains dated from 3,600 to 2,500 BP, but it was not carried into Polynesia.[11]
