About this trial
This study is exploring how psilocybin (a psychedelic drug) may improve mood and wellbeing. Many people report feeling better after taking psilocybin, but it is not clear why. The CoPEWell study will test whether these improvements come from the psychedelic experience itself (the "trip") or from direct effects on the brain. To study this, up to 120 participants will be enrolled to receive psilocybin either while awake or asleep and can expect to be on study for up to 4 months.

Primary outcomes
Change in Warwick Edinburgh Mental Wellbeing Scale (WEMWBS) score: Psilocybin Awake versus Asleep
WEMWBS is a 14-item survey scored on a 5 point likert scale. The total range in scores is from 14 to 70 where higher scores indicate better mental wellbeing. Reported here for psilocybin administered while awake to psilocybin administered while asleep.
Change in Warwick Edinburgh Mental Wellbeing Scale (WEMWBS) score: Psilocybin Asleep versus Placebo Asleep
WEMWBS is a 14-item survey scored on a 5 point likert scale. The total range in scores is from 14 to 70 where higher scores indicate better mental wellbeing. Reported here for psilocybin administered while asleep to and placebo administered while asleep.
Secondary outcomes
Change in Brief Experiential Avoidance Questionnaire (BEAQ): Psilocybin Awake versus Asleep
BEAQ is 15-item survey scored on a 6 point likert scale. The total range is scores if from 15 to 90 where higher scores indicating greater avoidance. Reported here for psilocybin administered while awake to psilocybin administered while asleep.
Change in Brief Experiential Avoidance Questionnaire (BEAQ): Psilocybin Asleep versus Placebo Asleep
BEAQ is 15-item survey scored on a 6 point likert scale. The total range is scores if from 15 to 90 where higher scores indicating greater avoidance. Reported here for psilocybin administered while asleep to placebo administered while asleep.
Change in Watts Social Connectedness (WCS) Scale: Psilocybin Awake versus Asleep
WCS is a 19-item survey scored on a visual analog scale. Scores are reported from 0-100 where higher scores interpreted to be more connectedness to others. Reported here for psilocybin administered while awake to psilocybin administered while asleep.
