Just about everyone in the Solomon Islands above the age of about five, save for Seventh Day Adventists, chews Betel Nut. Day and night. You're never much farther than spitting distance from a Betel Nut stall in the Sols.
Chew an areca nut and some betel leaf (more like a stalk in these parts), add some powdered lime (locally produced from crushed coral) and you'll be mildly stimulated and need to spit copious quantities of red liquid. Chew it for a few years and your teeth go black. Chew it for decades and you're a prime candidate for cancer of the mouth.
