The coca in Coca-Cola:

The Coca-Cola we know today still contains coca -- but the ecgonine alkaloid is removed from it. Perfecting that extraction took until 1929, so before that there were still trace amounts of coca's psychoactive elements in Coca-Cola. As Dominic Streatfield describes in Cocaine: An Unauthorized Biography, the extraction is now done at a New Jersey chemical processing facility by a company called Stepan. In 2003, Stepan imported 175,000 kilograms of coca for Coca-Cola. That's enough to make more than $200 million worth of cocaine. They refer to the coca leaf extract simply as "Merchandise No. 5."

The facility is guarded.
