The purpose of the ongoing MA SOR program is to address the overdose crisis in Massachusetts by increasing access to FDA-approved medications for the treatment of opioid use disorder (MOUD), and supporting the continuum of prevention, harm reduction, treatment, and recovery support services for opioid use disorder (OUD), stimulant use disorders, and other concurrent substance use disorders (SUD). Populations to be served include these high risk populations: Black, Indigenous, and people of color (BIPOC), LGBTQIA+, individuals who have experienced a prior nonfatal overdose, youth and families impacted by the opioid crisis, persons with history of incarceration, pregnant and parenting women, individuals experiencing homelessness, individuals at risk of contracting and/or currently living with infectious disease, people who use stimulants alone and/or with other drugs, and persons with co-occurring mental health disorders. Goals include Goal 1: Increase access to evidence-based treatment for people with opioid and/or stimulant use disorders. Goal 2: Support the full continuum of prevention, harm reduction, treatment, and recovery support services for transitional aged youth and young adults. Goal 3: Increase access to recovery support services for people with or at risk for developing opioid and/or stimulant use disorders. Goal 4: Increase access to overdose prevention education, harm reduction and drug user health services. Goal 5: Strengthen the workforce’s ability to provide evidence-based prevention, intervention, treatment and recovery support services to people with opioid and/or stimulant use disorders. Total number to be served over the project period: 62,035 individuals (9,185 of which will be GPRA eligible).
