People who currently use MDMA or have used it in the past show impairments in verbal working memory, specifically on a computation span task, compared to non-users. Current users also show deficits on a reading span task. The impairment on computation span persists even after statistically controlling for the use of cannabis and other drugs, suggesting MDMA may have a specific effect on certain executive functions.
