Betel chewing creeps into the New World.
Areca nut has been chewed either alone or as a component of the betel quid since ancient times. It has been estimated that more than 10 percent of the world's population chew it for its mild psychoactive effects. Betel is chewed in New Zealand and Australia by immigrants from India now dwelling in these countries. Various forms of areca nut preparations are available in Asian groceries throughout New Zealand. The regular use of betel will, in time, stain the mucosa, gums, and teeth. This habit is discouraged in many countries because of its oncogenic, addictive, and dysaesthetic properties. Dentists and other health professionals should be aware of the effects of this habit.
