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