A systematic review of 25 studies found that psilocybin-assisted psychotherapy (PAP) produces a large reduction in anxiety symptoms within groups (Hedge's g = 0.96) and a small reduction compared to control groups (Hedge's g = 0.48). However, the studies varied widely in psychotherapy format, dosing, session structure, and outcome timing, and high heterogeneity persisted even after accounting for these differences. The authors conclude that PAP shows promise for treating anxiety across different diagnoses but caution that variability in study quality, design, sample representativeness, and high heterogeneity limit confidence in the findings. More rigorous trials with diverse populations are needed.

A systematic review and meta-analysis of five randomized controlled trials found that mindful hypnotherapy—an intervention combining hypnotic induction with mindfulness suggestions—produced large reductions in psychological distress (effect size 0.61) and stress (0.75), and a large increase in mindfulness (1.38) compared to waitlist and active control groups. The authors recommend future research on a wider range of clinical problems, use of active controls, measures of hypnotizability, and studies with diverse populations.

This special issue explores the intersections between psychedelic experiences, mystical states, and hypnosis, addressing key questions about their similarities, differences, and clinical utility. It examines whether mystical experiences can be facilitated without drugs, the role of suggestion in psychedelics, and the potential of hypnosis and meditation to induce such states. The collection also investigates how psychedelics and hypnosis might enhance creativity and spiritual growth. By presenting thought-provoking answers, it deepens understanding of these non-ordinary states of consciousness and their therapeutic implications.
