Cocaine in the cola -- Red Bull isn't the first

Ever wondered why Red Bull gave you so much energy? It could be the cocaine.

Six German states have told retailers to stop selling Red Bull Cola energy drinks after a test found a trace amount of cocaine. The bans started Friday after a sample test conducted by authorities in North Rhine-Westphalia state found 0.4 micrograms per liter in the drink.

Germany's Federal Institute for Risk Assessment said Monday that the cocaine level was too low to pose a health risk but will be doing additional testing.
