American Psychiatrists' Opinions About Classic Hallucinogens and Their Potential Therapeutic Applications: A 7-Year Follow-Up Survey.

Background: Psilocybin, a classic hallucinogen, may eventually be approved by the United States Food and Drug Administration for treatment-resistant depression. However, we are aware of only one published national survey of American psychiatrists regarding their opinions about hallucinogens and hallucinogen-assisted therapy, conducted by our group in 2016. Here, we report a repeat survey, using virtually identical methods, assessing whether American psychiatrists display greater optimism about the therapeutic use of hallucinogens in 2022-23.
