Let me introduce you to a legal, yet highly addictive, drug called BETEL NUT. I've seen it being widely consumed all around the Southern parts of Asia and the Pacific islands (where it naturally grows)... but here in Papua New Guinea, they take it to another level. And they chew it differently than anyone else (with a mustard seed + lime + dried seashells).
More than half the population of PNG chew betel nut daily, or "buai" as they call it in the local language." Over the last 3 days as I've been around the country, I've seen everyone from little kids (under 10) to grandparents in their 90s spitting this red stuff out of their mouths.
This video will educate you a little bit about betel nut -- what it is, how it's used, what it does to your health, how the epidemic is effecting the local economy, and if you watch until the end, you'll see my reactions as I try it for the first time.
