Coca-Cola originally contained cocaine

coca cola

From a blend of coca leaf and kola nut extracts used in the original 1885 formula. At the time, cocaine was a common ingredient in medicines, and Coca-Cola was developed as a medicinal elixir. When cocaine was later discovered to be harmful and addictive, the company phased it out, leaving only trace amounts to justify the name. By 1929, the beverage was completely cocaine-free.
