Improving Overdose Prevention and Treatment in the Criminal Legal System
JCOIN supports researchers working in partnership with criminal legal system and behavioral health treatment professionals to build the evidence base for effective SUD service delivery, implementation, and dissemination. Each JCOIN study addresses a specific gap in the SUD care cascade, at one or more intercept points including jails, prisons, community corrections, problem-solving courts, and juvenile justice agencies. The studies evaluate the effectiveness and/or implementation of behavioral interventions, digital therapeutics, comprehensive patient-centered treatments, and medications for opioid use disorder (MOUD) in communities throughout the United States.
JCOIN research projects vary in size, complexity, and duration, from small pilot studies to large multisite clinical trials. JCOIN 1.0 projects were conducted between 2019-2025. JCOIN 2.0 studies were launched beginning in 2025.
