(2001) found no significant effects of moderate MDMA use, however, heavy use was found to be associated with global decreases in serotonin transporters, believed to be a consequence of serotonin neurotoxicity, with women being more susceptible to “dose-related decreases in serotonin transporters” than men. According to Reneman et al. (2001) these decreases in serotonin transporters could be reversed, however long-term effects in the parieto-occipital cortex and occipital cortex is also a possibility. In their study of MDMA usage and the drug’s effects on mood and cognition, Parrott and Lasky (1998) found that even an acute dose of MDMA caused reduced memory ability, with user’s scores being significantly worse than those of the control group at every test session. These impairments to user’s memory remained apparent even in future sessions when the drug had not been administered and were more pronounced in the regular Ecstasy users than in the first time users (Parrot & Lasky, 1998). Parrot and Lasky (1998) also observed impaired visual search task performance following acute administration and slower visual scanning in regular MDMA users, backing up the warnings of Reneman et al. (2001) of possible long-term effects in the parieto-occipital cortex and occipital cortex. In tape recorded interviews, subjects under the influence of MDMA in Parrot and Lasky’s (1998) study gave various reasons their poor performance. There were reports such as their mind kept wandering while they were trying to complete the memory task, the shapes kept moving even though the subject knew they should not, everything moves too quickly to keep up, and that concentration and memory were extremely difficult (Parrot & Lasky,
