I made a mention of the Compund Chem advent infographics here last year, and I was inspired to do something similar this year- with interesting tidbits about chemistry (and of course sharing the Compound Chem calendar for this year too! :)) )

(Explores: Edith Humphrey, Fritz Haber, and Leo Baekeland!)
Heroin is still legal in some places. It's used as a pain killer and is actually a pretty good drug for it. It was actually really common in birth suite!
