Johns Hopkins Center for Psychedelic and Consciousness Research:

Online Study of Naturalistic Psilocybin Use

If you intend to take psilocybin and are interested in contributing to the scientific understanding of the effects of psilocybin, the Johns Hopkins study team would like to ask you questions before and after your experience.

This study will involve filling out a set of up to 5 online surveys over the period of 2 weeks before and up to 3 months after your planned psilocybin experience.

Each survey will take between 10 and 30 minutes.

The goal of this survey is to learn more about the positive and/or negative outcomes of using psilocybin in naturalistic settings (meaning outside a research laboratory), and any potential factors that could affect those outcomes.

Participants must be at least 18 years old, read and write English fluently, and plan to use psilocybin within the next 6 months.
