Opioid & Heroin Addiction Treatment in California

Medically reviewed by Bradley Tourtlotte, MD · Written by the California Treatment Centers clinical team · Last reviewed June 2026

Opioid addiction, whether it involves heroin or prescription painkillers, is a chronic medical condition, not a moral failing. At California Treatment Centers, we treat opioid use disorder with the same compassion and clinical rigor we would bring to any other illness. With multiple California locations and statewide service, help is closer than you might think.

How Opioid Addiction Takes Hold

Opioids, including heroin, oxycodone, hydrocodone, and morphine, attach to receptors in the brain that control pain and reward. Over time, the brain adapts, requiring more of the drug just to feel normal. What may have started as pain management or experimentation can quickly become physical dependence. Signs of opioid use disorder include:

• Using more than intended or for longer than planned
• Strong cravings and preoccupation with the next dose
• Withdrawal symptoms when not using
• Continued use despite harm to health, work, or relationships
• Switching from pills to heroin or other opioids as access changes

Overdose Risk Is Real

Opioid overdose is a leading cause of accidental death, and the risk is higher than ever because of how unpredictable the drug supply has become. Overdose can stop breathing within minutes. Naloxone (Narcan) can reverse an overdose if given in time, and we encourage everyone affected by opioids to keep it on hand. If you witness an overdose, call 911 immediately.

Why Detox Comes First

Opioid withdrawal is rarely life-threatening, but it can be intensely uncomfortable, with muscle aches, nausea, anxiety, and powerful cravings that often drive people back to using. Our medical detox program manages these symptoms safely and humanely, setting the stage for lasting recovery.

Medication-Assisted Treatment Works

For opioid use disorder, medication-assisted treatment (MAT) is one of the most effective, evidence-based approaches available. Medications such as buprenorphine, methadone, or naltrexone reduce cravings and withdrawal, stabilize brain chemistry, and dramatically lower overdose risk. MAT is not trading one addiction for another; it is medically supervised treatment that helps people stay alive and engaged in recovery.

A Full Continuum of Care

We combine medication with therapy at every stage. After detox, many clients enter residential treatment for focused recovery work, then continue with outpatient services that fit around work and family. Counseling, relapse-prevention skills, and peer support address the emotional and behavioral sides of addiction.

We are in-network with most major insurers, and insurance verification is always free and confidential. Our admissions team can explain MAT, answer your questions, and help you start treatment quickly, because with opioids, time matters. Reach out today.
