A meta-analysis of 26 studies found that recreational ecstasy use is associated with moderate to large impairments in memory. Short-term memory showed a moderate deficit, while long-term memory showed a large deficit; the difference between these two types was not significant. Verbal memory was strongly impaired, significantly more than visual memory, which showed only a small impairment. Visual memory problems may be partly due to concurrent cannabis use. The total number of ecstasy tablets consumed over a lifetime did not predict memory performance, suggesting that other factors may be more important.
