ABSTRACT
BACKGROUND: Recent research trends are to specify the relation between patterns of ecstasy use and side effects, possibility of dependency, tolerance and long term neurocognitive damage. The objective of this study was to assess the impact of regular ecstasy use on its acute and subacute effects. SUBJECTS AND METHODS: At the first stage, we recruited 120 subjects. If participants continued regular use of ecstasy in this period, they were asked to participate in the second stage of the research 6 months later. Thirty-five subjects attended the second stage of the study, 5 of which were excluded because they had less than 5 drug experiences during the last 6 months. At last, we recruited 30 novice ecstasy users by means of the snowball technique in Tehran, Iran. The pattern of use and experienced effects of ecstasy was documented at the beginning and after 6 months of regular consumption with a self administered questionnaire. RESULTS: Little or no change was observed in acute effects. Those subacute effects that had considerable increase in frequency were anxiety, depression, aggression, memory impairment, poor concentration and learning problems. CONCLUSION: Small change in acute effects suggests low possibility of tolerance after at least 6 months of regular use. Our results support long term neurocognitive damage and mood impairment with ecstasy use.
