How is Substance Use Disorder categorized by severity and what criteria define it?

Severity is defined by geographic region of use.

Mild (2–3 criteria), Moderate (4–5), Severe (6+), based on impairment criteria including craving, unsuccessful attempts to cut down, repeated use despite harm, tolerance, withdrawal, time spent seeking, and social/interpersonal impairment.

Severity is based solely on the amount used per week.

Criteria do not include cravings or withdrawal.

Substance Use Disorder is diagnosed and its severity is rated by how many diagnostic criteria are present within a 12-month period. There are 11 possible criteria, and the more you meet, the more severe the disorder. The thresholds are: 2–3 symptoms for a mild level, 4–5 for moderate, and 6 or more for severe. The criteria cover both behavioral and physiological aspects, including impaired control (using more than intended or unsuccessful efforts to cut down), social impairment (problems at work, school, or relationships), risky use (use in hazardous situations), and pharmacological factors (tolerance and withdrawal). Craving, defined as a strong desire or urge to use, and withdrawal symptoms when not using are included as criteria. This framework isn’t based on how much someone uses per week or on geographic regions, and cravings or withdrawal are indeed part of the defining criteria.
