Coca — cocaine
Pemberton 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 did once contain an estimated nine milligrams of cocaine per glass, but in 1903 it was removed.[28] Coca-Cola still contains coca flavoring.
After 1904, instead of using fresh leaves, Coca-Cola started using "spent" leaves — the leftovers of the cocaine-extraction process with cocaine trace levels left over at a molecular level. [29] To this day, Coca-Cola uses as an ingredient a cocaine-free coca leaf extract prepared at a Stepan Company plant in Maywood, New Jersey.
In the United States, the Stepan Company is the only manufacturing plant authorized by the Federal Government to import and process the coca plant,[30] which it obtains mainly from Peru and, to a lesser extent, Bolivia. Besides producing the coca flavoring agent for Coca-Cola, the Stepan Company extracts cocaine from the coca leaves, which it sells to Mallinckrodt, a St. Louis, Missouri pharmaceutical manufacturer that is the only company in the United States licensed to purify cocaine for medicinal use.[31]
Kola nuts — caffeine
Kola nuts act as a flavoring and the source of caffeine in Coca-Cola. In Britain, for example, the ingredient label states "Flavourings (Including Caffeine)."[32] Kola nuts contain about 2 percent to 3.5 percent caffeine, are of bitter flavor and are commonly used in cola soft drinks. In 1911, the U.S. government initiated United States v. Forty Barrels and Twenty Kegs of Coca-Cola, hoping to force Coca-Cola to remove caffeine from its formula. The case was decided in favor of Coca-Cola. Subsequently, in 1912 the U.S. Pure Food and Drug Act was amended, adding caffeine to the list of "habit-forming" and "deleterious" substances which must be listed on a product's label.
Coca-Cola contains 46 mg of caffeine per 12 fluid ounces (12.9 mg per 100 ml).[33]
Besides cocaine, the coca leaf contains a number of other alkaloids, including methylecgonine cinnamate, benzoylecgonine, truxilline, hydroxytropacocaine, tropacocaine, ecgonine, cuscohygrine, dihydrocuscohygrine, nicotine and hygrine. When chewed, coca acts as a mild stimulant and suppresses hunger, thirst, pain, and fatigue.
