Areca nut

Betel nut chewing is addictive due to the presence of the stimulant arecoline, and causes adverse health effects, mainly oral and esophageal cancers, and cardiovascular disease. When chewed with additional tobacco in its preparation (like in gutka), there is an even higher risk, especially for oral and oropharyngeal cancers. With tobacco it also raises the risk of fatal coronary artery disease, fatal stroke, and adverse reproductive effects including stillbirth, premature birth, and low birth weight.
Consumption by hundreds of millions of people worldwide—mainly of South/Southeast Asian origins—has been described as a public health emergency. Provided by Wikipedia
