In collaboration with the New England Association of Drug Court Professionals (NEADCP) and the Opioid Response Network of New England (ORN), we created a webinar series for individuals who wanted to learn more about Medication Assisted Treatment (MAT) and its role in justice settings. The goal of this webinar was to familiarize professionals in the drug court system with opioid use disorder (OUD) as a disease and its effects. The webinar also explained how MAT works, answered the question “what is the ‘treatment’ in medication assisted treatment,” and examined why the science of OUD is important to effective treatment courts. Leading experts in the field were present to answer discussion questions.
