So, this came out in late May.  People freaked.  6 states in Germany have banned Red Bull Cola, not Red Bull.  The bans started when a test found 0.4 micrograms per liter of coca leaf extracts in the drink.  Germany's Federal Institute for Risk Assessment said that the cocaine level was too low to pose any health risks.  Red Bull has come out and said that their drink is "harmless and marketable in both the U.S. and Europe."  They also said that similar coca leaf extracts are used worldwide as flavoring.  Marketable, yes.  But I will not touch a Red Bull Cola after hearing this.  According to authorities, the substance requires the beverage to be classified as a narcotic, requiring a license for sale. (Of course, even Coca-Cola didn't become entirely cocaine-free until 1929).
