Heroin

It seems like once it was a pharmaceutical drug. And it was used as sedative for coughs as it is written in the picture. Interesting!

I guess Aspirin was not the only breakthrough for Bayer. It was marketed as a "non-addictive" replacement for morphine which had been then (1890s) used for cough suppressant.

the spoilsport.
