Dissociative drug dependence including Ketamine or PCP, sustained partial remission

After a diagnosis of Dissociative drug dependência including Ketamine and PCP, and often following a treatment episódio or other intervention (including self-help intervention), there is a significant reduction in dissociative drug consumption for more than 12 months, such that even though intermittent or continuing dissociative drug uso has occurred during this period, the definitional requirements for dependência have not been met.
