Stimulant-induced obsessive-compulsive or related transtorno including amphetamines, methamphetamine and methcathinone 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 stimulants. The intensity or duration of the symptoms is substantially in excess of analogous disturbances that are characteristic of Stimulant intoxicação or Stimulant abstinência. The amount and duration of stimulant 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 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 obsessive-compulsive or related symptoms (e.g., a history of prior episodes not associated com stimulant uso).
