BERLIN, GERMANY - MARCH 01: In this photo illustration the owner of a shop that sells electronic cigarettes demonstrates how to use one on March 1, 2012 in Berlin, Germany. The German government has announced that it classifies the liquids used in electronic cigarettes as pharmaceuticals because the liquids contain nicotine, and that sale of the liquids requires certification. An estimated 1.2 to 2 million people in Germany use electronic cigarettes, and the retailers that sell the liquids now face the problem that they are breaking the law. Electronic cigarettes have thus far been in a legal grey area with some lawmakers pushing for conclusive studies to determine their potential health effects.
