Subjective effects of psilocybin and relationship of mystical experience to clinical outcomes.

(Top) Subjective effects as measured by the Mystical Experience Questionnaire (MEQ 30) in each treatment group at 7 hours post-session 1 (psilocybin first n=14, niacin first n=15), 7 hours post-session 2 (psilocybin first n=12, niacin first n=14), and 26 weeks post-dose 2 (psilocybin first n=11, niacin first n=12). Asterisks indicate significance level of between-group differences. (Bottom) Mediation model in which total scores on the MEQ transmit a portion of the effects of psilocybin versus niacin treatment on change in anxiety and depression is shown.
