Addiction Treatment Glossary
Plain-English definitions of the most-googled terms in addiction medicine. Each entry cites the primary public-domain source (SAMHSA, NIH, CDC, peer-reviewed journals) and links to where the term applies on RehabHive.
Why a glossary?
Addiction medicine has its own vocabulary — much of it acronyms (SBIRT, MAT, MOUD, PHP, IOP, ASAM, AUD, SUD) — that show up in clinician notes, insurance authorization letters, and treatment-plan documents. Knowing what these mean lets you read the paperwork, ask better questions, and verify your care against current best practice.
Each entry below is sourced to public-domain originals (SAMHSA Treatment Improvement Protocols, NIH/NIDA, CDC, peer-reviewed journals) and updated on the date shown. We don't paraphrase commercial proprietary frameworks; what's not in the public domain isn't in the glossary.
