Betel nut chewing can lead to various health issues. It has been classified as a known human carcinogen by the IARC and is linked to cancers of the mouth, pharynx, esophagus, and stomach. Chewing betel nut regularly increases the risk of these cancers. It is estimated that over 390,000 new cases of oral cancer occur globally each year, with 228,000 of these cases occurring in South and Southeast Asia. Betel nut chewing also negatively impacts the environment as remnants are often spit out on the ground, increasing pollution levels and risk of illness. It sends a negative message to younger generations who are increasingly using tobacco and betel nut products at early ages.
