Dissociative drug dependence including Ketamine or PCP, sustained partial remission (Q40554)

After a diagnosis of Dissociative drug dependence including Ketamine and PCP, and often following a treatment episode 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 use has occurred during this period, the definitional requirements for dependence have not been met.
