Coke Caffeine

Someone once told me that the only reason there’s caffeine in Coke is to make it more addictive. Meaning, caffeine isn’t a natural byproduct of the Coke making process; it’s added. And it’s not added because it adds taste; it doesn’t add any (good) taste. So it’s only purpose is to make Coke more addictive. I don’t know, that’s interesting to me.
