Socio-cognitive functioning in stimulant polysubstance users
The use of more than one psychotropic substance, concurrently or consecutively, is termed polysubstance use (PSU) (EMCDDA, 2002; Meyerhoff, 2017). PSU was previously diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) as the use of at least three substances (excluding caffeine and nicotine) within the same 12-month period. However, this definition has recently been removed from the DSM-5 (American Psychiaric Association, 1994; American Psychiatric Association, 2013).
