Peoria sits within Maricopa County, one of the most heavily impacted regions in the United States for fentanyl and methamphetamine-related overdose deaths.
The West Valley location of Peoria means residents have access to a growing network of treatment providers across the broader Phoenix metropolitan area, including programs that accept AHCCCS (Arizona’s Medicaid program) and those funded through opioid settlement dollars.
Because Arizona does not require a Certificate of Need for behavioral health services, facilities can enter the market without proving community demand. As a result, the number of licensed providers has grown substantially since 2018.
One example is Community Medical Services in Peoria (10689 N 99th Ave), which provides outpatient medication for opioid use disorder (MOUD), including buprenorphine and naltrexone, along with counseling and peer support services. For those requiring a higher level of care, programs across the county accept both commercial insurance and AHCCCS.
Maricopa County committed $4.3 million in April 2025 through the One Arizona Distribution of Opioid Settlement Funds Agreement to expand services at 17 organizations across the county. These funds target prevention, harm reduction and care coordination, and are expected to reach full operational status through 2026.
For people who need immediate medically supervised detox, the dominant concern in Peoria is polysubstance use driven by fentanyl and methamphetamine. Because both substances carry serious withdrawal risks, medical detox is strongly recommended over attempting to stop use without professional support.
Detox and residential treatment facilities operating in Peoria must be licensed by the Arizona Department of Health Services (ADHS), Division of Public Health Licensing, Bureau of Residential Facilities Licensing, under Arizona Administrative Code (A.A.C.) Title 9, Chapter 10. This framework requires detox programs to provide medically supervised environments with licensed physicians and nurses on staff and clearly defined protocols for managing withdrawal.
