Substance Use Disorder Treatment
Medication-assisted treatment, evidence-based therapy, and residential care for alcohol, opioid, stimulant, and other substance use disorders.
Key Takeaways
- SUD is diagnosed using DSM-5 criteria — severity ranges from mild (2–3 symptoms) to severe (6+ symptoms).
- Medication-Assisted Treatment (MAT) — methadone, buprenorphine, naltrexone for opioids; naltrexone, acamprosate, disulfiram for alcohol — substantially improves outcomes.
- Evidence-based therapies include CBT, Contingency Management, Motivational Interviewing, and 12-Step Facilitation.
- Levels of care range from outpatient through PHP, residential, and medical detox — driven by severity, withdrawal risk, and prior treatment history.
- Co-occurring mental health conditions affect roughly half of people with SUD — integrated dual diagnosis treatment is essential.
Substance Use Disorder (SUD) affects more than 48 million U.S. adults each year. It is a treatable medical condition — not a moral failing. The right combination of medication, therapy, and level of care depends on the substance, the severity, and what other conditions are in the picture.
This page covers how SUD is diagnosed, the medications and therapies with the strongest evidence, and how to know when residential or intensive outpatient care is appropriate. Our admissions team will match you to a licensed program at no cost.
How SUD Is Diagnosed
DSM-5 SUD criteria include 11 symptoms across four domains: impaired control (using more or longer than intended, persistent desire to cut down), social impairment (continued use despite problems, neglecting responsibilities), risky use (using in dangerous situations, continued use despite physical or psychological problems), and pharmacological criteria (tolerance, withdrawal).
Severity is rated based on number of symptoms: mild (2–3), moderate (4–5), severe (6+). Diagnosis is made for the specific substance — Alcohol Use Disorder, Opioid Use Disorder, Stimulant Use Disorder, etc.
Medication-Assisted Treatment (MAT)
For Opioid Use Disorder: methadone, buprenorphine (Suboxone), and extended-release naltrexone (Vivitrol) are all FDA-approved and substantially reduce overdose, illicit use, and relapse. Methadone and buprenorphine are agonist or partial-agonist treatments; naltrexone is an antagonist. Each has its place.
For Alcohol Use Disorder: naltrexone (oral or extended-release injectable), acamprosate, and disulfiram are FDA-approved. Naltrexone reduces craving and heavy drinking; acamprosate supports abstinence; disulfiram creates an aversive reaction to alcohol.
For Tobacco Use Disorder: nicotine replacement, varenicline, and bupropion.
No FDA-approved medication is yet available for stimulant or cannabis use disorder, though several are in active research.
Evidence-Based Psychotherapies
Cognitive Behavioral Therapy (CBT) helps identify triggers and develop coping strategies. Motivational Interviewing resolves ambivalence about change. Contingency Management uses tangible rewards for verified abstinence — one of the most effective approaches for stimulant use disorder. 12-Step Facilitation and engagement with mutual support (AA, NA, SMART Recovery) substantially improve long-term outcomes when paired with professional treatment.
Levels of Care
Level of care is driven by severity, withdrawal risk, and prior treatment history:
| Level | When It Fits | Typical Length |
|---|---|---|
| Outpatient + MAT | Mild–moderate; stable home environment | Ongoing, 6+ months |
| IOP | Moderate; needs more structure | 3 days/wk, 8–12 weeks |
| PHP | Severe; daily structure, home at night | 5 days/wk, 4–8 weeks |
| Residential | Severe; home destabilizing; prior treatment failures | 30–90 days |
| Medical Detox | Significant withdrawal risk (alcohol, benzos, opioids) | 3–10 days, then step-down |
Medical detox is for managed withdrawal — particularly important for alcohol and benzodiazepine withdrawal (potentially life-threatening) and opioid withdrawal (rarely life-threatening but severe). After detox, patients typically step down to residential, PHP, IOP, or outpatient + MAT.
Dual Diagnosis (Co-Occurring Mental Health)
Roughly half of people with SUD also have a co-occurring mental health condition — most commonly depression, anxiety, PTSD, bipolar disorder, or ADHD. Integrated dual diagnosis treatment — addressing both conditions through one coordinated team — produces substantially better outcomes than sequential or siloed treatment. See our Dual Diagnosis page for detail.
Insurance Coverage
Under the federal Mental Health Parity and Addiction Equity Act (MHPAEA), most plans must cover SUD treatment at the same level as physical health care. Outpatient counseling and MAT are nearly always covered. IOP, PHP, residential, and detox require pre-authorization and concurrent review but are covered when medically necessary. We verify benefits at no cost.
Frequently Asked Questions
Is MAT really better than abstinence-only treatment for opioid use disorder?
Yes. Multiple randomized trials and large observational studies show that methadone and buprenorphine substantially reduce overdose death, illicit opioid use, and relapse compared with abstinence-only approaches. For opioid use disorder, MAT is the standard of care.
How long does residential addiction treatment last?
Most programs run 30, 60, or 90 days. Longer stays generally produce better outcomes, particularly for severe SUD or co-occurring mental health conditions. Insurance typically authorizes care in 7- to 14-day blocks based on continued medical necessity.
Do I need medical detox before residential treatment?
Medical detox is necessary when withdrawal carries significant medical risk — particularly alcohol, benzodiazepines, and opioids. After 3–10 days of medically supervised detox, patients typically step down to residential or another level of care.
Will insurance cover SUD treatment?
Under federal Mental Health Parity law, most plans must cover SUD treatment at the same level as physical health care. Specific coverage varies by plan and level of care. We verify benefits at no cost and tell you exact numbers before you commit.
