The Associated Press reports that Austria's health ministry found detectable traces of cocaine samples of Red Bull Cola energy drinks... keep in mind that this is Red Bull's Cola and not their ubiquitous Energy Drink. They use the Coca leaf as a flavoring but are supposed to remove any cocaine.
Before you go out and buy a case, Red Bull Spokeswoman says that any traces are very slight and do not pose a health risk; and the company maintains that its Cola is "harmless and marketable in both the U.S. and Europe."
So how much did they find? - 0.4 micrograms/liter.
To put things in perspective, the EPA allows a maximum threshold of arsenic in drinking water of 10 micrograms/liter. That's 25 times more than how much cocaine the Austrians found.
