Best for addiction counselors, IOP and outpatient clinicians, harm reduction workers, and any provider working with clients who use opioids, sedatives, or multiple substances. Particularly useful at intake, after a missed session, following a recent relapse, or when a client mentions overdose fear directly. Pairs well with naloxone training, harm reduction conversations, and level-of-care decision-making. Not a diagnostic instrument and not a substitute for clinical judgment — it is a structured frame for the clinical conversation you are already having.
