This conceptual paper argues that psychedelic-assisted therapy could help people stop criminal behavior by supporting the deep internal changes linked to long-term desistance: identity reconstruction, emotional processing, trauma healing, and meaning-making. Drawing on criminology and psychedelic science—not clinical trials—it proposes that post-release, community-based settings are the only ethical place for this work, since prisons introduce safety and consent barriers. While evidence on recidivism outcomes is still theoretical and not causal, the paper outlines why PAT may fit as a complementary part of reintegration services for individuals facing high rates of trauma, addiction, and mental illness.
