After traces of cocaine were found in samples of Red Bull Cola, the drink may be banned in Germany. Samples of the drink were examined by German food authorities, and were found to contain 0.4 micrograms of cocaine per litre, which was said to have been caused by the method used to process cocoa leaves.

Six German states have already ordered retailers to stop selling the beverage. More are expected to follow suit this week.

Germany's Federal Institute for Risk Assessment said that the cocaine levels found were too low to pose a health risk. A more detailed report is expected tomorrow.

Red Bull is currently available in 148 countries worldwide. It is banned in Denmark, Norway, Uruguay, and now German due to health fears.
