Addiction treatment is not one-size-fits-all. The clinical approach that produces the best outcomes for alcohol use disorder is fundamentally different from what works for opioid dependence, benzodiazepine addiction, or stimulant use disorder. The medications differ. The withdrawal management differs. The behavioral interventions differ. Even the co-occurring mental health conditions most commonly associated with each substance differ.

The most important decision in addiction treatment is not whether to get help — it is finding the right clinical match for the specific substance, the specific severity, and the specific person. Drug Rehab Headquarters maintains clinically reviewed treatment guides for 18 substance categories, each written to give you the information you need to make that decision clearly and confidently.

Addiction Treatment by Substance — All 18 Guides

Each guide below covers the neuroscience of that specific addiction, withdrawal and detox, evidence-based treatment approaches, medication options, level-of-care guidance, and how to choose a program. Select your substance or call (866) 720-3784 for a free clinical assessment.

Levels of Addiction Treatment Care

Addiction treatment is not a single program type — it is a continuum of care matched to clinical need. ASAM's criteria define four primary levels, and selecting the right level is as important as selecting the right facility.

What Makes Addiction Treatment Work

NIDA's research identifies several principles that consistently distinguish effective addiction treatment programs from ineffective ones. These are the markers to look for — and the questions to ask:

Insurance Coverage for Addiction Treatment

The Affordable Care Act and the Mental Health Parity and Addiction Equity Act together establish a legal requirement that most insurance plans — including Medicaid, Medicare, and private marketplace plans — cover addiction treatment at the same level as other medical conditions. This means:

• Medically necessary detox is covered as a medical benefit
• Residential and inpatient treatment is covered when clinically indicated
• IOP and outpatient treatment are covered
• MAT medications (buprenorphine, methadone, naltrexone) are covered under pharmacy and/or medical benefits
• Medicaid covers addiction treatment in all 50 states, including MAT

Coverage details, prior authorization requirements, and in-network provider lists vary by plan. Verify your insurance online or call (866) 720-3784 — we verify coverage for free before making any referrals.
