Obsessive-compulsive or related transtorno induced by multiple specified psychoactive substances is characterised by either repetitive intrusive thoughts or preoccupations, normally associated com anxiety and typically accompanied by repetitive behaviours performed in response, or by recurrent and habitual actions directed at the integument (e.g., hair pulling, skin picking) that develop during or soon after intoxicação com or abstinência from multiple specified psychoactive substances. The intensity or duration of the symptoms is substantially in excess of analogous disturbances that are characteristic of intoxicação com or abstinência from the multiple specified psychoactive substances. The amount and duration of the multiple specified psychoactive substances uso must be capable of producing obsessive-compulsive or related symptoms. The symptoms are not better explained by a primary mental transtorno (in particular an Obsessive-compulsive or related transtorno), as might be the case if the symptoms preceded the onset of the uso of multiple specified psychoactive substances, if the symptoms persist for a substantial period of time after cessation of the multiple specified psychoactive substance uso or abstinência, or if there is other evidence of a pre-existing primary mental transtorno com obsessive-compulsive or related symptoms (e.g., a history of prior episodes not associated com multiple specified psychoactive substances uso).
