I dunno 'bout that: "Was Cocaine once an ingredient in Coca-cola? No, there’s never been any cocaine added in Coca‑Cola and there never will be." https://www.coca-cola.com/mv/en/about-us/faq/was-cocaine-onc... Is someone suggesting they would obfuscate their sacred history?
Cocaine was never a coca-cola ingredient. The intro to the article exaggerates for narrative effect. Coca leaf was, and still is, an ingredient in coca-cola. So both cocaine and coca-cola are made with coca leaf, but coca-cola is not and never has been made with cocaine.
The FDA considers caffeine an ingredient in things like soda and energy drinks because it's dosed and added to the beverage. But the FDA doesn't consider the naturally occurring caffeine in coffee beans as an ingredient in something like coffee beans or a canned cold brew. A manufacturer might list caffeine content to help consumers but they aren't required to do so.
Is gluten an ingredient in flour? Not to the FDA but it's still in there. Is sugar an ingredient in fresh squeezed orange juice? No but it's still in there.
