How many DSM-5 criteria must be met to diagnose someone with a substance use disorder?

To diagnose an individual with a substance use disorder according to the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), a person must meet at least two of the specified criteria within a 12-month period. These criteria encompass various aspects of behavior, physiological responses, and the impact of substance use on an individual's life. Meeting this threshold indicates that the individual is experiencing significant impairment or distress as a result of their substance use.

By requiring at least two criteria, the DSM-5 aims to ensure that the diagnosis reflects a pattern of behavior that warrants treatment and intervention, rather than a one-time or minimal issue with substance use. This approach helps clinicians identify individuals who may benefit from further assessment and appropriate interventions tailored to their needs. The criteria range from aspects such as tolerance and withdrawal symptoms to social, occupational, or recreational impairments caused by the substance use.
