Cola is a carbonated beverage that originally contained caffeine from the kola nut and cocaine from coca leaves, and was flavored with vanilla and other ingredients. Most colas now use other flavoring (and caffeinating) ingredients with a similar taste and no longer contain cocaine. It became popular worldwide after pharmacist John Pemberton invented Coca-Cola in 1886. His non-alcoholic recipe was inspired by the Coca wine of pharmacist Angelo Mariani, created in 1863, but did not contain cocaine. Coca-Cola is a major international brand. It usually contains caramel color, caffeine and sweeteners such as sugar or high fructose corn syrup.
