What defines substance use disorder according to DSM-5-TR?

• A. A problematic pattern of use leading to clinically significant impairment or distress, manifested by at least two criteria within a 12-month period.
• B. Recurrent use in hazardous environments without impairment.
• C. A single instance of use with no consequences.
• D. Any use of a substance at any time.

Answer: (A)

Substance use disorder is diagnosed when there is a problematic pattern of substance use that leads to clinically significant impairment or distress, demonstrated by at least two of eleven diagnostic criteria within a 12-month period. This captures why the description is correct: it requires both a pattern of use and meaningful impact on functioning, not just a one-off event. DSM-5-TR treats this as a spectrum, with severity increasing as more criteria are met (2–3 mild, 4–5 moderate, 6+ severe). The criteria cover cravings, taking in larger amounts or over longer periods than intended, unsuccessful efforts to cut down, a lot of time spent obtaining or using the substance, giving up activities, continued use despite problems caused by use, hazardous use, tolerance, and withdrawal, among others. The other options don’t fit because they describe use without impairment, a single occasion, or any use at all, none of which meet the diagnostic threshold.
