  1. Polysubstance

    Polysubstance is used in the American Psychiatric Association's Diagnostic and Statistical Manual for Mental Disorders to refer to three or more drugs to which an individual has become dependent. In the DSM nosology, Polysubstance dependence indicates that the use of any one of the substances does not meet the diagnostic criteria for substance dependence but the combined use of the drugs does meet substance dependence diagnostic criteria. Two research studies have sought to determine if polysubstance dependence patients differ in any important ways from patients with a single-drug substance dependence but each study defined polysubstance dependence differently, which makes comparisons difficult.
