Substance use disorders — SAMHSA overview
What substance use disorders are, how they are diagnosed, and the treatments with the strongest evidence.

SAMHSA's substance use pages cover alcohol, opioid, stimulant, cannabis, and other substance use disorders. The framing is squarely medical: SUDs are chronic, treatable health conditions, not moral failings.
The pages link directly into FindTreatment.gov and the SAMHSA National Helpline (1-800-662-HELP), the two best U.S. starting points for getting into care.
Mental Hum's library is a curated index of authoritative third-party resources. The summary above is our own framing; the full information lives at the source.
