idk if everyone knows this but they still flavor coca-cola with coca leaves, which are what you refine into cocaine. There's a single company in Illinois who is running on a license written in the 1940s who are authorized to import the coca leaves; they extract the cocaine out of them and then, with armed guards, load the cocaine onto a FedEx truck which takes it to an incinerator.

quick edit: my rambling is in fact not entirely true. please refer to rebug by @SaberaMesia for more accurate fun fact
