Betel Nut Fourth Global Psychoactive

Betel (areca) nut is the fourth most used psychoactive drug in the world, coming after nicotine, alcohol, and caffeine. Researchers estimate that at least 10 percent of the world’s population, around 600 million people, regularly chew betel nut. They keep using it despite strong evidence that long-term chewing carries a high risk of cancer and heart disease.
