Addiction treatment exists on a continuum from most intensive to least intensive. Understanding the levels helps you choose the right starting point.

Medical detox

5-10 days of medically supervised withdrawal management. The starting point for anyone with physical dependence. Not treatment itself but medical stabilization before treatment begins.

Residential / inpatient

24/7 care in a treatment facility. 30-90 days. Intensive therapy, structured environment, complete immersion. Best for severe addiction, failed outpatient attempts, or unsafe home environments.

Partial hospitalization (PHP)

Full-day treatment (6-8 hours, 5 days/week) while living at home or in sober living. 4-6 weeks. Best for stepping down from residential or when symptoms are too severe for IOP.

Intensive outpatient (IOP)

Part-day treatment (3-4 hours, 3-5 days/week). 8-12 weeks. Allows working while in treatment. Best for mild-moderate addiction with stable home environment.

Standard outpatient

Weekly therapy sessions. Ongoing. Best for maintenance after completing higher levels or for mild conditions.

Sober living

Substance-free housing with peer support and structure. 3-12 months. Bridges the gap between treatment and independent living.

MAT

Medication-assisted treatment can be integrated at any level. Buprenorphine, methadone, and naltrexone for opioids. Naltrexone and acamprosate for alcohol.

A clinical assessment determines the appropriate level. SAMHSA at 1-800-662-4357 provides free assessments and referrals.

Can I skip residential and go to outpatient?
