With Mr. Mony translating we were told that the dried pieces of sliced nut are wrapped in betel leaves and flavored before chewing. Apparently they use a mixture of "snail slime" and boiled cow manure as the basis for the flavoring. It ends up looking like a white liquid not entirely dissimilar to whiteout. I didn't smell it to see if the aroma is at all similar because the list of ingredients was deterrent enough.
Smoking cigarettes was traditionally a vice left to men and the betel nut the choice of women. Today I understand that it is considered old fashioned but it still provides a stimulant effect coupled with a peppery taste. It certainly isn't as offensive to the people around you as smoking so to my way of thinking it is a preferable vice.
