🏥 Medical Detoxification

The process of safely managing the physical symptoms of withdrawal under medical supervision. Detox is the first step for many people, but it's not treatment. It clears the body while treatment addresses the mind.

What it involves
  • 24/7 medical monitoring during acute withdrawal
  • Medication to manage withdrawal symptoms safely
  • Duration: 3-10 days depending on substance and severity
  • Hospital or dedicated detox facility settings
  • Transition planning to next level of care
Who it's for
  • Anyone withdrawing from alcohol or benzodiazepines (medically necessary)
  • Heavy opioid users wanting a safe, managed withdrawal
  • Anyone at medical risk during withdrawal
  • First step before residential or PHP treatment
Cost indicator

High cost. Most insurance covers medically necessary detox. SAMHSA can help find funded options.

Important notes
  • Detox alone rarely produces sustained recovery, it must be followed by treatment
  • Tolerance resets during detox, relapse risk is extremely high immediately after
  • Discuss MAT options with the detox team before discharge
Non-negotiable: Alcohol and benzodiazepine detox must be medically supervised. Attempting these withdrawals without medical support can be fatal. Call SAMHSA at 1-800-662-4357 to find a medically supervised detox facility near you.

🏠 Residential (Inpatient) Treatment

Live-in treatment providing intensive therapy, structure, and 24-hour support in a therapeutic environment. The gold standard for severe addiction, early recovery, and people needing removal from a triggering home environment.

What it involves
  • Residential living in a treatment facility
  • Structured daily schedule: therapy, groups, activities
  • Individual and group therapy sessions daily
  • Duration: 28 days (short-term), 60-90 days, 6-12 months (long-term therapeutic communities)
  • Medical staff on-site or available
Who it's for
  • Severe addiction requiring removal from home environment
  • Co-occurring mental health conditions needing intensive support
  • Multiple prior treatment attempts with outpatient
  • Unstable or unsafe home environment
  • High relapse risk with less intensive care
Cost indicator

Highest cost. Insurance covers many programmes. State-funded options exist. SAMHSA helpline for funded placements.

What the research shows
  • Longer residential stays (90+ days) produce better outcomes
  • Treatment quality varies enormously, ask about therapy types, staff credentials
  • Transition planning is critical, discharge without a step-down plan dramatically increases relapse risk

🌅 Partial Hospitalisation Programme (PHP)

The bridge between residential and outpatient. PHP provides hospital-level intensive treatment during the day (5-7 days per week, 5-8 hours per day) while allowing you to sleep at home or in sober living. High intensity, high flexibility.

What it involves
  • 5-7 days per week attendance, 5-8 hours per day
  • Group therapy, individual therapy, psychiatric services
  • Medical monitoring available during programme hours
  • Duration: typically 2-6 weeks
  • Step-down from residential or step-up from IOP
Who it's for
  • People leaving residential who need a structured transition
  • People requiring intensive treatment who can't leave home (work, family)
  • Co-occurring mental health conditions needing psychiatric oversight
  • When IOP hasn't been sufficient
Cost indicator

Moderate-high cost. Most insurance covers PHP. Often significantly less expensive than residential.

Key considerations
  • You return to your home environment each evening, requires a safe, sober home situation
  • Evening support structure (sober living, family support) significantly improves PHP outcomes
  • Transportation to and from programme needs planning

🌤️ Intensive Outpatient Programme (IOP)

The most common treatment level for people who can't or don't need residential care. IOP provides structured group and individual therapy 3-5 days per week while you maintain work, school, and family commitments.

What it involves
  • 3-5 days per week, 3-4 hours per session
  • Group therapy as the primary modality
  • Individual therapy sessions (weekly or biweekly)
  • Substance use monitoring (urine screens)
  • Duration: 8-16 weeks typically
Who it's for
  • People who can't attend PHP due to work or family obligations
  • Step-down from PHP or residential
  • Moderate addiction severity with stable home environment
  • First formal treatment for people with good social support
Cost indicator

Moderate cost. Insurance typically covers IOP. Significantly more accessible than higher levels of care.

What works best in IOP
  • Attendance at all scheduled sessions, dropout is the main predictor of poor outcomes
  • Supplementing with peer support meetings on non-programme days
  • Having a sponsor or recovery coach alongside formal treatment
  • Sober home environment during IOP attendance

🌿 Standard Outpatient Treatment

Individual and/or group therapy sessions 1-2 times per week. The maintenance level of care for people in stable recovery, or the appropriate first step for mild addiction severity with strong support systems.

What it involves
  • Weekly or biweekly individual therapy sessions
  • Group therapy options (once or twice weekly)
  • Medication management if on MAT
  • May include drug testing
  • Duration: ongoing, typically 6-12 months minimum
Who it's for
  • Step-down from IOP as recovery stabilises
  • Mild addiction severity with strong social support
  • Ongoing maintenance therapy for people in stable recovery
  • People on MAT who need regular monitoring and support
Cost indicator

Lowest formal treatment cost. Widely covered by insurance. Sliding-scale options available at community mental health centres.

When to step back up
  • Relapse or near-relapse
  • Significant increase in relapse risk score
  • Major life stressor or crisis
  • Feeling like outpatient alone isn't providing enough support

💊 Medication-Assisted Treatment (MAT)

FDA-approved medications combined with counselling and support. The most effective treatment available for opioid use disorder, reducing overdose mortality by 50-60%. Not a standalone, MAT works best alongside therapy and peer support.

Available medications
  • Buprenorphine (Suboxone), opioids, office-based prescribing
  • Methadone, opioids, OTP clinics
  • Naltrexone (Vivitrol), opioids and alcohol
  • Acamprosate, alcohol
  • Disulfiram, alcohol (deterrent)
  • Varenicline / NRT, nicotine
Who it's for
  • Anyone with opioid use disorder, first-line treatment
  • People with alcohol use disorder seeking pharmacological support
  • People at high overdose risk
  • Can be combined with any other level of care
Cost indicator

Low to moderate. Medicaid covers most MAT. Generic buprenorphine is inexpensive. SAMHSA helpline for funded options.

Access
  • Any GP can now prescribe buprenorphine (no waiver since 2023)
  • Telehealth MAT prescribing widely available
  • findtreatment.gov for MAT providers near you
  • SAMHSA: 1-800-662-4357

🤝 Peer Support & Mutual Aid

Free, community-based recovery support from people with lived experience. 12-step programmes, SMART Recovery, recovery coaching, and peer specialists. Peer support is not treatment, but research shows it dramatically improves treatment outcomes when combined with formal care.

Types available
  • AA, NA, CA and other 12-step fellowships
  • SMART Recovery (science-based, non-12-step)
  • Celebrate Recovery (faith-based)
  • Certified peer recovery specialists / coaches
  • Recovery community organisations (RCOs)
  • Online communities and recovery forums
What the evidence shows
  • AA produces comparable outcomes to CBT at lower cost (Cochrane 2020)
  • Peer support specialists reduce hospitalisation rates
  • Sponsor relationships are among the strongest predictors of long-term sobriety
  • Community belonging is a resilience factor against relapse
Cost indicator

Typically free. 12-step, SMART, and most peer support is no-cost. Recovery coaching and peer specialists may have modest fees.

🎯 How to choose the right level

🏥Choose medical detox if: You use alcohol or benzodiazepines heavily (medically necessary), or you want medical support through any withdrawal.
🏠Choose residential if: You have severe addiction, an unsafe or triggering home environment, multiple prior outpatient failures, or significant co-occurring mental health needs.
🌅Choose PHP if: You need intensive treatment but can return home each evening to a safe environment, or you're stepping down from residential.
🌤️Choose IOP if: You need structured treatment but can't leave work or family, you have a stable home, or you're stepping down from PHP.
🌿Choose outpatient if: You're in stable recovery maintaining therapy, or you have mild severity with strong support systems.
💊Add MAT if: You have opioid use disorder (strongly recommended) or alcohol use disorder and want pharmacological support, at any level of care.
🤝Add peer support always: Peer support improves outcomes at every level of care. Use the Meeting Finder and Accountability Partner Tracker alongside formal treatment.

The most important thing about levels of care

The right level of care is the one that provides enough structure and support to hold you through early recovery, but not more than is necessary. Under-treating addiction (insufficient care intensity for the severity) produces relapse. But over-treating creates unnecessary disruption to life, career, and family while not producing better outcomes than matched treatment.

The American Society of Addiction Medicine (ASAM) criteria provide a standardised framework for matching people to appropriate levels of care based on 6 dimensions: intoxication and withdrawal potential, biomedical conditions, emotional and cognitive conditions, readiness to change, relapse potential, and recovery environment. A good addiction assessment will use these criteria. Ask your assessor specifically about their ASAM criteria assessment.

Stepping up and stepping down

Treatment is not linear. Most people move up and down the continuum based on how they're doing. A relapse during outpatient care might indicate a need to step back up to IOP or PHP. Sustained stability in residential might allow a step-down to PHP while still in the 28-day programme. This flexibility is clinically appropriate and shouldn't be experienced as failure. Recovery is not a straight line, and treatment flexibility reflects that reality.

Track your recovery status with the Relapse Risk Calculator weekly. Consistently elevated scores, especially in the emotional and social domains, are a signal that your current level of care may not be sufficient. Bring this data to your treatment provider and have the conversation about whether stepping up is appropriate.
