Quote from : A History of the World in 6 Glasses Book

This original version of Coca-Cola contained a small amount of coca extract and therefore a trace of cocaine. (It was eliminated early in the twentieth century, though other extracts derived from coca leaves remain part of the drink to this day.) Its creation was not the accidental concoction of an amateur experimenting in his garden, but the deliberate and painstaking culmination of months of work by an experienced maker of quack remedies.
