Answer
Yes, the original recipe for Coca-Cola, created in 1886 by John Pemberton, did contain alcohol. It was marketed as a "tonic" and contained coca leaves and kola nuts, both sources of caffeine. However, in 1903, the Pure Food and Drug Act banned the use of cocaine, leading Coca-Cola to remove the coca leaves from its recipe and subsequently introduce "Coca-Cola Classic" as the non-alcoholic version we know today.
