Psychotic transtorno induced by outro especificado psychoactive substance is characterised by psychotic symptoms (e.g., delusions, hallucinations, disorganised thinking, grossly disorganised behaviour) that develop during or soon after intoxicação com or abstinência from a specified psychoactive substance. The intensity or duration of the symptoms is substantially in excess of psychotic-like disturbances of perception, cognition, or behaviour that are characteristic of intoxicação com or abstinência from a specified psychoactive substance. The amount and duration of uso of the specified psychoactive substance must be capable of producing psychotic symptoms. The symptoms are not better explained by a primary mental transtorno (e.g., Esquizofrenia, a Mood transtorno com psychotic symptoms), as might be the case if the psychotic symptoms preceded the onset of the uso of the specified psychoactive substance, if the symptoms persist for a substantial period of time after cessation of the uso of the specified psychoactive substance or abstinência from the specified psychoactive substance, or if there is other evidence of a pre-existing primary mental transtorno com psychotic symptoms (e.g., a history of prior episodes not associated com the uso of the specified psychoactive substance).
