Fentanyl accounted for 52% of all drug-related overdose deaths in Los Angeles County in 2024 — and fentanyl withdrawal, while rarely fatal on its own, carries serious risks that require careful medical oversight. Alcohol withdrawal is one of the only substance withdrawals that can be directly life-threatening without proper clinical management.

Medical detox is the clinical process of clearing substances from the body safely under the supervision of licensed medical staff. It is not a complete treatment on its own — it is the first, critical phase of a full treatment episode. Detox addresses physical dependence: the withdrawal symptoms the body experiences when a substance is removed. After detox, residential treatment addresses the psychological and behavioral dimensions of addiction. Most licensed inpatient programs include detox as part of the full program; patients move directly from detox into residential treatment without leaving the facility.
What Happens During Detox?
From admission, a medical team reviews the patient's substance history, medical history, and current vitals and develops a detox protocol specific to them — including medications to ease withdrawal symptoms and manage complications. Patients are monitored throughout the process with 24-hour clinical oversight. The detox phase typically lasts 5–10 days depending on the substance and severity of use.
Fentanyl Detox: What to Expect
Fentanyl withdrawal typically begins 12–24 hours after last use and peaks around days 2–3. Symptoms include severe muscle aches, insomnia, anxiety, nausea, vomiting, diarrhea, and intense cravings. Medication-assisted treatment — particularly buprenorphine (Suboxone) — is highly effective at managing fentanyl withdrawal and significantly reduces relapse risk during and after detox.
Fentanyl + Xylazine: Why Medical Supervision Matters
Some illicit fentanyl circulating in Los Angeles County contains xylazine — a veterinary tranquilizer that does not respond to naloxone. Xylazine causes skin wounds and prolonged sedation, and requires a different clinical response than opioid overdose alone. Medical supervision during fentanyl detox is essential for this reason.
Alcohol Detox: Why Medical Supervision Matters
Alcohol withdrawal is one of the only substance withdrawals that can be directly life-threatening. In severe cases it can cause seizures, hallucinations, and delirium tremens (DTs). Anyone with a significant daily drinking habit should never attempt to stop cold turkey without medical supervision. Licensed inpatient programs use established protocols — including carefully managed medication — to ensure alcohol detox is safe.
Meth Detox: Symptoms and Timeline
Methamphetamine withdrawal is primarily psychological rather than medically dangerous, but it is intensely uncomfortable. The acute withdrawal phase — severe fatigue, depression, increased sleep, and intense cravings — typically lasts 1–2 weeks. A longer period of mood disturbances and anhedonia can follow. Given that meth is the #1 drug type in LA County overdose deaths in 2024, programs in the network have extensive experience treating meth use disorder.
How Long Does Detox Take?
Alcohol detox: 5–7 days. Opioid/fentanyl detox: 5–10 days. Meth detox acute phase: 7–14 days. Benzodiazepine detox: 7–21 days (tapered; never abrupt). These are general guidelines — actual timelines are determined by a clinical team at admission.
Is Medical Detox Covered by Insurance?
Yes. Under California SB 855, state-regulated insurance plans must cover medical detox as part of the substance use disorder treatment benefit. Most PPO plans cover detox as an acute medical service. Call (213) 461-2298 and a placement advisor will verify coverage before referral.
