The betel nut, once known as "green gold," has been identified as a carcinogen by the International Agency for Research on Cancer. Despite this finding, it continues to be widely consumed in China and Taiwan. The lack of regulation around betel nuts, as they are neither food nor medicine, has led to concerns about potential additives and health risks. Lawmakers in Taiwan are calling for the revision of laws and regulations to address this food safety loophole, suggesting that betel nuts should be managed similarly to tobacco under the Tobacco Hazard Prevention Law.
