Why areca nut is banned?

Areca catechu was used as medicine in the history of China. Internationally, the carcinogen 1 identified by the International Agency for Research on Cancer of the World Health Organization is even listed as a drug in some countries. Betel nut is never food. Medical research has found that chewing betel nut will increase the risk of oral cancer by 8.4-9.9 times. The 5-year survival rate of oral cancer is low.

This kind of dangerous goods is sold casually like snacks, which poses a great threat to national health. As a teacher, I know that there is a publicity campaign against drugs and smoking every semester, but there has never been a publicity campaign about betel nut. Therefore, betel nut will permeate the next generation if it is not removed.
