Summary

This trial will involve 120 healthy individuals between the ages of 21 and 70 who have moderate-to-lower-than-average mental well-being. They will be divided into four groups and given either a

Who is the study for?
This trial is for healthy individuals aged 21 to 70 who feel their mental well-being is moderate to low. Participants must not have any serious health issues and should be interested in how different environments might influence the effects of psilocybin, a substance being studied for its potential to improve mood.
What is being tested?
The study tests if the setting affects how psilocybin works on mood. One group gets a placebo (no active drug), while others get up to 25mg of psilocybin. They're placed in one of two different contexts designed to see if environment changes the drug's impact.
What are the potential side effects?
Psilocybin can cause headaches, nausea, increased heart rate, blood pressure changes, psychological distress or confusion temporarily during use. The specific side effects may vary depending on the context it's taken in.

Trial Design

4Treatment groups
Experimental Treatment
Placebo Group
Group I: Psilocybin C2Experimental Treatment2 Interventions
Following screening and a baseline assessment visit, healthy volunteers will receive one dose of up to 25mg psilocybin in a context (Context 2) that is hypothesized to modulate acute and post-acute drug effects.
Group II: Psilocybin C1Experimental Treatment2 Interventions
Following screening and a baseline assessment visit, healthy volunteers will receive one dose of up to 25mg psilocybin in a context (Context 1) that is hypothesized to modulate acute and post-acute drug effects.
Group III: Placebo C1Placebo Group2 Interventions
Following screening and a baseline assessment visit, healthy volunteers will receive one dose of an inactive placebo in a context (Context 1) that is hypothesized to modulate acute and post-acute drug effects.
Group IV: Placebo C2Placebo Group2 Interventions
Following screening and a baseline assessment visit, healthy volunteers will receive one dose of an inactive placebo in a context (Context 2) that is hypothesized to modulate acute and post-acute drug effects.
