In psychiatric diagnosis, '''substance abuse''' and '''substance dependence''' were distinct classifications used in the ''Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition'' (DSM-IV). Substance abuse referred to a maladaptive pattern of substance use causing clinically significant impairment or distress, without the compulsive use, tolerance, or withdrawal seen in dependence.<ref name="ref1" /><ref name="ref2" /> Substance dependence was considered a more severe condition characterized by physiological and behavioral symptoms, including tolerance and withdrawal.<ref name="ref3" /><ref name="ref2" /> With the publication of DSM-5 in 2013, these categories were merged into a single diagnosis called "substance use disorder," measured on a continuum from mild to severe.<ref name="ref4" /><ref name="ref5" />

The distinction in the DSM-IV was based on different criteria. A diagnosis of substance abuse required one or more specific symptoms within a 12-month period, such as failing to fulfill major obligations, using substances in hazardous situations, or experiencing recurrent legal or social problems due to use.<ref name="ref1" /><ref name="ref2" /> In contrast, a dependence diagnosis required three or more of seven specific criteria, which included tolerance, withdrawal, loss of control over use, and a great deal of time spent obtaining, using, or recovering from the substance's effects.<ref name="ref3" /><ref name="ref1" />

=== DSM-5 Revision ===
The decision to combine the abuse and dependence categories into a single "substance use disorder" in the DSM-5 stemmed from research indicating that the distinction between the two was not always clear in clinical practice. The DSM-5 criteria for substance use disorder include 11 symptoms, largely incorporating the previous criteria for both abuse and dependence. The severity of the disorder (mild, moderate, or severe) is determined by the number of criteria met by an individual. This spectrum-based approach is intended to better capture the varying levels of substance-related problems. The legal problems criterion was removed, and a criterion for craving was added in the transition to DSM-5.
