How Long Does Detox Take? Timelines by Substance

One of the most common questions people ask when preparing for treatment is: How long does detox take? The answer depends on several factors, including the substance used, length of use, co-occurring conditions, and individual health. At Costa Mesa Detox Center, we provide safe, medically supervised detox programs for all substances—tailored to your unique needs.

What Is Detox?

Detox is the first step in addiction recovery, during which the body clears itself of drugs or alcohol. It’s also when withdrawal symptoms peak, which is why 24/7 medical support and emotional care are so important. Our residential detox program ensures comfort and safety at every stage.

General Detox Timelines by Substance

Alcohol

• Onset: 6–12 hours after last drink
• Peak Symptoms: 24–72 hours
• Duration: 5–7 days

Alcohol detox can involve seizures, hallucinations, and a dangerous condition called delirium tremens (DTs). Medical supervision is essential.

Opioids (Heroin, Prescription Painkillers)

• Onset: 8–24 hours after last dose
• Peak Symptoms: 48–72 hours
• Duration: 5–10 days

Symptoms include muscle pain, nausea, anxiety, and intense cravings. Opioid detox often includes Medication-Assisted Treatment (MAT).

Benzodiazepines (Xanax, Ativan, Klonopin)

• Onset: 1–4 days
• Peak Symptoms: 4–7 days
• Duration: 10–14+ days

Benzo detox must be done slowly under medical supervision to prevent seizures or rebound anxiety. Learn more about our benzo detox protocols.

Methamphetamine

• Onset: 12–24 hours

Meth detox primarily causes psychological symptoms: depression, anxiety, fatigue, and insomnia. Supportive care is critical for emotional stabilization.

Cocaine detox focuses on mental health support and monitoring for suicidal thoughts or extreme depression.

We treat dependence on Adderall, Ambien, and other medications through our prescription drug detox program.

What Happens After Detox?

Detox is only the beginning. After stabilization, we help you transition into rehab or outpatient care. Long-term recovery depends on therapy, support, and relapse prevention planning.
