I knew about #Sartre & #mescaline from my 'existentialist' youth days, but don't remember much. So, while thinking about something else re Sartre, I did a quick search & found this short piece with a couple of interesting references:
August 21, 2019 – In the thirties, both Jean-Paul Sartre and Walter Benjamin experimented with the hallucinogenic drug mescaline.
