Cannabis is illegal in Germany, but each state has different regulations on how much is allowed for personal possession. Germany's drug commissioner called for a nationwide standard for the amount of cannabis allowed for personal possession. Daniela Ludwig told the Funke Media Group that it is "difficult" when each German state has different regulations. A person in possession of only "a small amount" of the drug can, according to the law, avoid prosecution. In Hamburg, a small amount is six grams, while in Berlin 15 grams are allowed.
