I've read about Hitler being on drugs, and that the nazis used drugs regularly to "enhance" or dumb down their soilders ect. I've always thought of this as a bit too much speculation, would love to get to the bottom of this.
P.S Love this sub!
I do not want to hamper further discussion, but this topic has been extensively covered by u/commiespaceinvader on numerous occasions, so you may be interested in this excellent response that deals with the drug use in the Third Reich and this one dealing more closely with Hitler himself. This thread also touches the topic.
