About opioid treatment programs in California

Opioid treatment programs (OTPs) provide medications for opioid use disorder (MOUD) - such as methadone, buprenorphine, or naltrexone - together with counseling and other support. In the United States, OTPs that dispense methadone are certified by SAMHSA and registered with the DEA. These listings are unrated: SAMHSA publishes no star ratings, inspections, or quality scores, so confirm services, licensing, cost, and availability directly.

Start with the level of care and the services a person needs - withdrawal management, medications for opioid use disorder, therapy, psychiatric care, or a sober living setting - then check licensing, accepted insurance, and cost. These SAMHSA listings are unrated, so the fit of the service matters more than any score.

Where you can, call each option in California and confirm services, licensing, cost, insurance, and current openings in writing. No ratings, inspections, or quality scores are published for these SAMHSA listings, so direct confirmation is the surest check.
