PsychEd: educational psychiatry podcast
The Meaning of Psychodelic
The word psychodelic comes from an exchange of letters between two famous figures in the world of psychidelic science and history. One is aldous huxley, the english philosopher and writer,. The other was humphrey osmond, who was working in weyburn, saskatchewan to do trials for people with alcohol use disorder. But i do also want to say that before this word was created from this correspondence, these medicines were called and classified, or understood quite different.
