Traces of Coccaine Found in Red Bull Cola?

Listen to this, Red Bull Cola has been banned in 6 German states due to a test which found a trace amount of cocaine in the product with supposedly 0.4 micrograms per liter in the drink.  5 other states have stopped the sale of the product in order to avoid possible violations.

Red Bull says the product is “harmless, and marketable in both the US and Europe,”  stating that similar extracts are used as flavoring, and a test they commissioned themselves found no cocaine traces.
