Coca-Cola

In 1886 the American chemist John Pemberton developed Coca-Cola© - 'French wine of coca, ideal tonic'. The ingredients included cocaine and kola nut extract, which contains caffeine. Within a few years, Coca-Cola and similar drinks had caused widespread cocaine addiction in America and so, in 1906, the cocaine in the Coca-Cola recipe was replaced with extra caffeine.

Coca-Cola originally contained cocaine, but this was replaced by caffeine in 1906. Science & Society Picture Library
