Codeine, not cocaine.
That's right, Hoffmann (Mr. Bayer) was trying to create something not as addictive as codeine by methylating morphine, but the result was the opposite. IIRC it was called heroin because Hoffmann had his staff try it and they said it made them feel like heroes. (Imagine Big Pharma asking its workers to take the jab to see how it worked before offering it to the public.)
