Coca leaves. They’re de-coked prior to use, but they’re still a controlled substance. Coke has an exception built into the law that effectively makes them the only country company in the US that can access them (possibly outside of medical, I’m not really sure and don’t care to check). There’s not a lot in the drink anymore as it is, just enough to keep the name.
Yep, swipe input with midnight brain do be making those alternative facts. Thanks for pointing it out.
