There is a surge of interest in psychedelics, and psychedelic-assisted psychotherapy is becoming increasingly accessible. However, most individuals using psychedelics do so outside of therapeutic contexts. It is important to understand the adverse...

Psychedelic-assisted therapy (PAT) has shown preliminary efficacy for psychiatric and physical health conditions. Although some people report naturalistic psychedelic use with so-called "underground" practitioners, little is known about PAT that occurs outside of controlled clinical settings or perspectives of these practitioners.

There is a surge of interest in psychedelics, including new stakeholders and greater media attention. There is a need to examine the information-seeking behavior of people using psychedelics naturalistically, given the importance of preparation and harm-reduction.
