Recreational use of MDMA (Ecstasy) is linked to impairments in syllogistic reasoning, a form of logical deduction. In a study comparing 22 MDMA users (average age 21.36) with 26 non-users (average age 21.31), users performed significantly worse on reasoning tasks, even after accounting for other drug use. However, this deficit was no longer statistically significant when differences in working memory capacity were considered. The findings suggest that MDMA-related declines in working memory and executive function may underlie the observed reasoning difficulties.
