Addressing the Opioid Crisis in American Indian & Alaska Native Communities in California: A Statewide Needs Assessment

A collaborative research team comprised of American Indian and Alaska Native researchers, urban Indian agency partners, Tribal entities, and students and staff from the University of Southern California (USC) conducted research from March – November 2018 with Tribal and urban populations throughout the state of California culminating in Addressing the Opioid Crisis in American Indian & Alaska Native Communities in California: A Statewide Needs Assessment. This report recognizes the need to address the opioid overdose crisis in AIAN communities in California and aims to identify gaps in prevention, treatment, and recovery services (including medication-assisted treatment, or MAT) targeted to these communities.
