On June 30, 1995, Drug Wars was put on the infamous German index by the BPjS.
Note: Indexed products by the BPjS/BPjM are illegal to sell or make available to minors in Germany and it is illegal to advertise for it in any form. But there is absolutely no law forbidding any adult to buy such a product. The only exception is when a game was in addition also confiscated (or put on the so-called "List B" for BPjM games), but this is rather seldom the case.
In this particularly case here, Drug Wars was just indexed, but not confiscated.
However, due to the fact that advertisement also means the presence of a product on the shelves of a store, the product will disappear from the public. But it can be bought in supporting stores "under the desk" (per request).
