A Three-Day Clinical Training with Andrew Tatarsky, PhD & Casey Paleos, MD
We are in the midst of a profound paradigm shift in how we understand addiction. Increasingly, clinicians are moving beyond seeing addiction solely as a disease and toward understanding it as a deeply meaningful human response to suffering—an adaptive attempt to regulate overwhelming emotions, cope with trauma, or survive difficult life circumstances. This shift transforms the therapeutic task: rather than focusing primarily on stopping a behavior, it invites us to focus first on the person, with compassion, curiosity, and deep respect.
Psychedelic-assisted therapy is opening remarkable new possibilities for transformation, but profound experiences alone don't produce lasting change. What matters is how those experiences are prepared for, held, and integrated. Integrative Harm Reduction Psychotherapy (IHRP) offers a relational, trauma-informed, dignity-centered framework that strengthens every phase of psychedelic work. What if the most effective entry point into psychedelic-assisted therapy for addictive and compulsive behaviors isn't abstinence, but honest, compassionate curiosity about why someone uses?
Meet Your Facilitators
Co-hosted by InnerMost, Journey Clinical, and MAPS, this three-day intensive brings together two of the field's most experienced practitioners to explore what becomes possible when harm reduction and psychedelic-assisted therapy weave together.
Andrew Tatarsky, PhD is an internationally renowned addiction therapist, trainer, and psychologist, and developer of IHRP—a framework built over four decades of clinical practice that meets people where they are, centers their autonomy, and treats the root of suffering rather than the behavior.
Casey Paleos, MD is a board-certified psychiatrist, co-founder of InnerMost, a leading psychedelic-assisted therapy researcher and clinician—having served as Principal Investigator and Therapy Supervisor on MAPS' Phase III MDMA trials and as a therapist on NYU's landmark psilocybin study.
Together, they've built a training that is part clinical education, part think tank, for clinicians who are ready to think more carefully and work more skillfully at the intersection of these two frameworks.
Across three days, you will:
Engage with the theoretical foundations and clinical applications of IHRP
Examine where harm reduction and psychedelic-assisted therapy share a philosophical root and what that means in practice
Build skills through demonstration therapy sessions and structured real play
Join a facilitated think tank on the emerging clinical questions at the intersection of IHRP and psychedelic-assisted therapy
Each day weaves together didactic teaching, case-based discussion, small group breakouts, and direct dialogue between Drs. Tatarsky and Paleos on the questions neither framework has fully answered alone.
