Did you know that the word "Heroin" is a genericized trademark? The morphine substitute (diacetylmorphine) was registered in 1898 by the German Friedrich Bayer & Company. The name comes from the Greek heros because of the euphoric feeling the drug provides.

Check it out, I'm not lying: Heroin.

The reason Bayer lost some of the trademark rights? Yep, you guessed it - it's just another thing we took away from the Germans in the Treaty of Versailles following World War I.

The same thing with "Aspirin".
