If you are reading this, the question you are probably trying to answer is some version of, what does addiction treatment actually involve, and which kind do I or someone I love actually need. That is the first question, and it deserves a direct answer.
This page is the index. It covers the continuum of care in plain language, lists every condition we treat with a one-line explanation of who each page is for, and offers a decision-tree pointer to the page on this site that fits your situation best. The pages it links to are the longer-form clinical reads.
The framework worth carrying into this is that treatment is not a single thing. It is a sequence of clinical levels of care, each with a specific purpose, that fit together into a continuum. Detox stabilizes the body. Residential begins the behavioral work. Outpatient programming consolidates the change. Aftercare carries it forward. Most durable recoveries involve several of these in sequence, not just one.
