Opioid use disorder is a medical condition with an unusually clear treatment answer: medication plus therapy, sustained over time, which reduces relapse and reduces death. Whether someone gets that combination is the single biggest variable in how this goes.

Golden Coast Rehab treats opioid use disorder in adults across San Diego County on an outpatient basis, whether the opioid was prescribed, bought, or both.

Nearly every illicit opioid in California now carries fentanyl risk, including pills that look pharmaceutical. That changes the overdose math for everyone using, regardless of tolerance or experience.

How opioid use disorder is treated here

Golden Coast Rehab holds California Department of Health Care Services (DHCS) substance use disorder certification 370254AP for outpatient detoxification, outpatient, intensive outpatient, and medication-assisted treatment. We do not provide residential or inpatient treatment, and there is no substance use partial hospitalization program here — partial hospitalization at Golden Coast Rehab is a specialty mental health service under our County of San Diego contract.

Outpatient detox

Opioid withdrawal is rarely life-threatening but is severe — muscle and bone pain, vomiting, diarrhea, insomnia, and profound restlessness. Very few people get through it unaided, which is why unsupported attempts so often end in relapse, and relapse after a period of abstinence is when overdose risk is highest because tolerance has dropped.

Medication-assisted treatment

This is the central treatment for opioid use disorder, not an optional extra. Medication relieves withdrawal and craving without producing a high at therapeutic doses, and it substantially reduces overdose death. It is delivered here alongside counseling, never as a prescription in isolation.

Intensive outpatient program

The core of treatment: several sessions a week of group and individual therapy while you live at home and, in most cases, keep working. This is where the actual work on triggers, craving, and the life around the using happens.

Outpatient program

A lighter weekly schedule that follows intensive outpatient and keeps the clinical relationship intact through the first year, when relapse risk is highest.

Common Signs of Opioid Use Disorder

These are the patterns that mark opioid use disorder, and the ones most associated with overdose risk.

01.highUsing to avoid withdrawal rather than to get high

The point of using has shifted from feeling good to feeling normal, and the day gets organized around not being sick.

Health Risks: This marks physical dependence and a sharp escalation in overdose and health risk.

02.highUsing alone

Using where nobody could respond if something went wrong.

Health Risks: Using alone is the single most common circumstance in fatal overdose. Naloxone and never using alone save lives.

03.moderateEscalating amounts or switching to stronger sources

Tolerance rising, or moving from pills to something cheaper or stronger.

Health Risks: Fentanyl contamination makes every unknown source potentially lethal, regardless of tolerance.

04.moderateDoctor shopping or buying outside a prescription

Running out early, seeking multiple prescribers, or purchasing pills from other sources.

Health Risks: Counterfeit pills are frequently pressed with fentanyl at inconsistent doses.

05.moderateEverything else falling away

Work, relationships, money, and health deteriorating while use continues.

Health Risks: The accumulating losses raise the risk of both overdose and suicide.

When a mental health condition is also present

Depression, anxiety, trauma, and bipolar disorder frequently sit alongside a substance use disorder, and treating only one of them is the most reliable way to end up back where you started. Both are treated here by one clinical team — see dual diagnosis, or the same care framed from the mental health side on co-occurring disorders.

Coverage and cost

Substance use treatment for Medi-Cal beneficiaries in San Diego County runs through the Drug Medi-Cal Organized Delivery System, administered by San Diego County Behavioral Health Services rather than by your managed care plan. If you have Medi-Cal in the county — any of the four plans — and you meet criteria, care here can be covered at no cost to you. See how Medi-Cal works here.

Questions, Answered

FAQs About Opioid Addiction

Is medication-assisted treatment just trading one drug for another?
No. At a therapeutic dose, medication for opioid use disorder relieves withdrawal and craving without intoxication, and it markedly reduces the risk of fatal overdose. The evidence here is strong and consistent. See our <a href="/treatment-programs/medication-assisted-treatment/">MAT page</a>.
How long will I need to be on medication?
That is a clinical decision made with you, and for opioid use disorder longer treatment is generally associated with better outcomes. There is no program-imposed deadline.
Can I detox from opioids as an outpatient?
Often yes, with medical support — the assessment determines whether it is appropriate for you. Withdrawal is difficult but rarely dangerous; the greater risk is what happens after, which is why we plan the handoff into treatment before detox begins.
What about fentanyl?
Assume any illicit opioid may contain it, including pills that look pharmaceutical. See our <a href="/addiction-treatments/fentanyl/">fentanyl page</a> for how that changes both risk and treatment.
Do you provide residential treatment for opioid addiction?
No. We are outpatient only. If you need residential or inpatient care, we will identify that at assessment and help you get there.
Does Medi-Cal cover opioid treatment?
Yes, through the Drug Medi-Cal Organized Delivery System, including medication, at no cost to you, on any San Diego County Medi-Cal plan when criteria are met.
How serious is the opioid overdose crisis right now?
NIDA data show 79,358 opioid-involved overdose deaths in the U.S. in 2023, down slightly from a peak of 81,806 in 2022 but still far above pre-2020 levels. Medication-assisted treatment paired with counseling remains the most evidence-supported approach to opioid use disorder. In San Diego County specifically, 441 people died of an opioid-related overdose in 2024, with 1,178 opioid-related emergency department visits the same year (CDPH, 2024).
What medications treat opioid use disorder?
FDA-approved medications are used to reduce cravings and withdrawal symptoms and support recovery, selected based on your assessment and medical history. Which one fits your situation is a clinical decision, not a fixed choice made for everyone.
Is opioid withdrawal dangerous?
It is rarely life-threatening, but it is severe enough — flu-like symptoms, intense cravings, insomnia, and muscle pain — that most people cannot get through it unsupported, which is why relapse during unsupervised withdrawal is common. Medical supervision manages symptoms and keeps you connected to next steps.
Can I keep working while on medication for opioid use disorder?
Yes, for most people — MAT is designed to be maintained alongside a job and daily responsibilities once you're stabilized on a dose. Early days may require more frequent visits before that stability is reached.
Do you provide residential treatment for opioid withdrawal?
No — Golden Coast Rehab does not provide residential or inpatient treatment. Care for opioid use disorder here is outpatient detox, outpatient and intensive outpatient programs, and medication-assisted treatment.
What if I've relapsed on opioids before starting medication?
That's part of what the assessment accounts for, not a barrier to starting. Prior relapse, including any overdose history, shapes how we approach your treatment plan and timing of medication.
