Then, of course, there’s the big change from the original Coke recipe vs what we have today with cocaine being replaced by caffeine.¹

1. I’m pretty sure that in no country does Coke still use cocaine.
How does this work legally? There is a (single) company that is licensed by the DEA to import coca, and they sell the non-psychoactive part to Coca-Cola. I think the psychoactive part goes toward DEA-approved research purposes, but I’m less sure about that.
Coca-Cola’s competitors do not receive or use coca through this process, only Coca-Cola.
I suspect the flavouring component is so diluted nowadays that its kept because it's a valuable sideline having that import license, and adds to the mystique a bit.
