Would you believe that when Coca Cola was first launched in 1886, its two key ingredients were cocaine and caffeine. The cocaine was derived from the coca leaf and the caffeine from kola nut, leading to the name Coca-Cola. The original recipe called for five ounces of coca leaf per gallon of syrup, a significant dose; in 1891, Candler claimed his formula (altered extensively from Pemberton’s original) contained only a tenth of this amount. Coca-Cola once contained an estimated nine milligrams of cocaine per glass. In 1903, it was removed.
