I wonder whether the active ingredient in the betel nuts is the same substance that also causes the cancer? Because if not, maybe the problem could be solved by extracting or sythesizing the active ingredient.
It has been synthesised. It's a mild stimulant but has a not-so-great toxicity profile. Probably best to leave it with the fibre you need to chew through.
