The Body Horror comes into play because the process is usually accomplished by low level employees of the Cartel having to use their bare feet to do the crushing of leaves and acid, meaning they are dissolving their own flesh in raw acid in the process, meaning the finished product likely has some remaining human skin tissue dissolved in it, making every druggie an indirect cannibal.
