Here's a brilliant example of too slick corporate communication:
The website of the Coca-Cola company states in a FAQ entry that "cocaine has never been an added ingredient for Coca-Cola". While that's technically true Coke did contain cocaine originally because it was a natural part of the coca leaf extract used to make Coca-Cola. It wasn't added it was already there.
Snopes has the story. The cocaine was only present in small amounts, but it was there. The amount of coca extract present in Coca-Cola was cut back in 1891 only a few years after the product was first invented, but trace amounts of cocaine remained until it was completely eliminated in 1929.
