Heroin use disorder is treated with the same approach as other opioid use disorders: medication to stabilize withdrawal and craving, therapy to address what sits underneath, and time. It is a serious condition and it responds to treatment.

Golden Coast Rehab treats heroin use disorder in adults across San Diego County on an outpatient basis.

One practical reality shapes everything: the heroin supply in California is widely contaminated with fentanyl, so overdose risk is no longer predictable from experience or tolerance.

How heroin 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

Heroin withdrawal peaks within a few days and is intensely uncomfortable rather than typically dangerous — pain, cramping, vomiting, insomnia, and severe restlessness. Medical support makes it survivable in practice, which matters because most unsupported attempts end in relapse, and relapse after abstinence is when overdose risk is at its highest.

Medication-assisted treatment

Medication is the treatment with the strongest evidence for heroin use disorder, including for reducing overdose death. It is delivered here alongside individual and group therapy.

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 Heroin Use Disorder

These are the patterns that matter clinically, and the ones that carry the most immediate physical risk.

01.highInjecting

Use by injection, and any sharing or reuse of equipment.

Health Risks: Injection carries risks of overdose, HIV, hepatitis C, endocarditis, and serious skin and soft-tissue infection.

02.highOverdose history

Any previous overdose, whether or not naloxone was involved.

Health Risks: Prior overdose strongly predicts future overdose. Carry naloxone and never use alone.

03.moderateUsing to prevent withdrawal

The day organized around staying ahead of sickness rather than around getting high.

Health Risks: Marks established physical dependence and a much harder path to stopping unaided.

04.moderateMoney and possessions disappearing

Borrowing, selling things, or debts that do not add up.

Health Risks: Financial collapse and legal consequences frequently arrive before anyone asks for help.

05.moderateWithdrawal from everyone who is not using

Social life narrowing to people who use, and cutting off those who do not.

Health Risks: Isolation removes both the supports and the people most likely to intervene in an overdose.

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 Heroin Addiction

Can I get treatment for heroin without going to residential rehab?
Yes. Outpatient medication-assisted treatment combined with intensive outpatient programming is an evidence-based path, and it is what we provide. If you need residential care, we will tell you at assessment.
How bad is heroin withdrawal?
Very uncomfortable, and rarely dangerous by itself. Medication substantially reduces the severity, which is the difference between getting through it and using again to make it stop.
Is heroin in San Diego contaminated with fentanyl?
Widely, yes. Assume any heroin may contain fentanyl. That is why naloxone and not using alone matter regardless of how long you have been using.
Will I have to be on medication forever?
Length of medication treatment is decided with your clinician. Longer treatment is generally associated with better outcomes in opioid use disorder, and there is no deadline imposed by the program.
What if I have hepatitis C or other health problems?
Tell us at intake. Those conditions are common with injection use and treatable, and we will coordinate the medical care alongside your treatment.
Does Medi-Cal cover heroin treatment?
Yes — treatment for heroin use, including medication-assisted options, is covered through San Diego County's DMC-ODS benefit at no cost to most members.
How does heroin use typically start?
NIDA research finds that about 80% of people who use heroin first misused prescription opioids, and heroin-involved overdose deaths totaled 3,984 in the U.S. in 2023, a continued decline from their 2016 peak as fentanyl has increasingly replaced heroin in the illicit supply. Understanding this pathway helps shape a treatment plan that also screens for prescription opioid history. San Diego County recorded 441 opioid-related overdose deaths across all opioids in 2024, per CDPH's surveillance dashboard.
Do you provide residential treatment for heroin addiction?
No — Golden Coast Rehab does not provide residential or inpatient treatment. Care for heroin use disorder here is outpatient: detox, intensive outpatient, standard outpatient, and medication-assisted treatment.
How soon can I start medication after my last use of heroin?
Timing depends on the medication and where you are in withdrawal, and it's determined during your assessment rather than a fixed rule. Starting too early or too late can both cause problems, which is why this gets individual attention.
Do I need to test negative for hepatitis C before starting treatment?
No — treatment for heroin use disorder isn't contingent on that testing, though we do screen for it as part of overall health assessment since it's common among people who've injected drugs. If you test positive, we help connect you to appropriate care rather than delaying substance use treatment.
Can I keep custody of my children while in treatment for heroin use?
Being in outpatient treatment does not by itself affect custody, and many people stay in their normal living situation throughout care since this is not residential treatment. Specific custody or family court questions are outside what we can advise on, but treatment engagement is generally viewed favorably in those proceedings.
What if I use heroin again while in treatment?
Relapse doesn't end your treatment — it gets addressed directly with your care team so your plan can adjust to what actually happened, including reassessing medication and safety. Hiding it is the riskier choice, especially given how often heroin is now contaminated with fentanyl.
