How to Chew Coca Leaves
While "chewing" is the popular term for it, the leaves should never actually be munched upon. Instead, they should be placed one-by-one into the cheek, forming a small saliva-generating ball which you just leave there. Because the stems of the leaves can hurt the inside of your cheek, you should remove them first. Some remove the stems by sliding the leaves between their two front teeth, while others use a lick-fold-tear method.
