What is the California MAT Expansion Project?

The California Department of Health Care Services (DHCS) created the California MAT Expansion Project to increase access to medication-assisted treatment (MAT), reduce unmet treatment need, and reduce opioid overdose-related deaths by investing in prevention, harm reduction, treatment, and recovery.

The California MAT Expansion Project supports more than 20 projects, including a focus on increasing services for Black, Tribal and Urban Indian, Hispanic and Latinx, and LGBTQ+ communities, people experiencing homelessness, people in criminal justice settings, and youth.

How is the California MAT Expansion Project funded?

The California MAT Expansion Project receives funding through:

  • State Opioid Response (SOR) III grant program
  • California State General Funds
  • Opioid settlement funds

California receives the SOR III grant from the Substance Abuse and Mental Health Services Administration (SAMHSA). Many SOR III programs are continuing efforts from the prior Fiscal Year 2018 and 2020 State Targeted Response (STR) and SOR grants. Learn more about SOR III projects on the California MAT projects page.

In late 2022, cities and counties in California received the first round of funding from settlements with opioid manufacturer Janssen Pharmaceuticals (parent company of Johnson & Johnson) and the “big three” distributors, McKesson, AmerisourceBergen, and Cardinal Health (“the Distributors”). California has joined additional lawsuits against manufacturers, distributors, and other entities responsible for aiding the opioid epidemic and anticipates receiving funds from future opioid judgment and settlement agreements. Learn more about California’s opioid settlement funds on the opioid settlement funds page.
