‪Slowly alternating between vivid and dry, “Blitzed: Drugs in the Third Reich” by Norman Ohler describes how use and abuse of drugs inluding meth, cocaine, and morphine fueled the German war machine and made the Blitzkrieg possible. Well worth the read.‬

There’s a lot of mood whiplash, and an obligatory CW/TW for descriptions of drug use, side effects of addiction, and experimentation on soldiers, children, and concentration camp victims. The roughest sections are at the end so if you hit your limit go ahead and stop because it’s not going to calm down.
