Detailed Description

This feasibility randomised trial assigns 40 healthy volunteers 1:1 to either a 21-day digital meditation programme or an active music-listening control. The aim is to evaluate operational feasibility, adherence, and preliminary signals of intervention acceptability.

Following the preparation period, all participants receive a single supervised oral dose of 25 mg psilocybin. Assessments include platform usability and feasibility measures, psychedelic preparedness, acute experience quality, and mental wellbeing at 2 weeks, 3, 6 and 9 months.

Primary outcomes are recruitment/retention and DIPP adherence; secondary outcomes are descriptive implementation metrics and preliminary efficacy measures to inform future trials.
