A qualitative analysis of participant expectations and experiences of psilocybin‐assisted psychotherapy for methamphetamine use disorder
Addiction December 22, 2025 Jonathan Brett, Toby Lea, Elizabeth Knock et al.
People with methamphetamine use disorder who took part in psilocybin-assisted psychotherapy reported that the treatment was acceptable and often transformative. Before treatment, participants held tempered hopes for positive outcomes. During the psychedelic sessions, many confronted challenging emotional or psychic obstacles by deliberately 'leaning into' them, a process that led to new understandings of themselves, their personal histories, and their relationships. Resolving these obstacles was associated with a reduced importance of methamphetamine in their lives. The therapeutic relationship—characterized by concentrated attention and deep interpersonal intimacy between participant and therapist—was seen as critical to these positive changes.
