Stimulant-induced psychotic transtorno including amphetamines, methamphetamine and methcathinone is characterised by psychotic symptoms (e.g., delusions, hallucinations, disorganised thinking, grossly disorganised behaviour) that develop during or soon after intoxicação or abstinência due to stimulants. The intensity or duration of the symptoms is substantially in excess of psychotic-like disturbances of perception, cognition, or behaviour that are characteristic of Stimulant intoxicação or Stimulant abstinência. The amount and duration of stimulant uso 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 stimulant uso, if the symptoms persist for a substantial period of time after cessation of the stimulant uso or abstinência, 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 uso of stimulants).
