Coca-Cola did once contain an estimated nine milligrams of cocaine per glass but after 1903 Coca-Cola started using, instead of fresh leaves, "spent" leaves - the leftovers of the cocaine-extraction process with cocaine trace levels left over at a molecular level. However, as cocaine is one of numerous alkaloids present in the coca leaf, it was nevertheless present in the drink. Today, the flavoring is still done with kola nuts and the "spent" coca leaf. In the United States, there is only one plant in New Jersey authorized by the Federal Government to grow the coca plant for Coca-Cola syrup manufacture.
That's What's up.
