Ecstasy use may result in lowered mood, anxiety or aggression in the days following use. Yet, few studies have investigated what factors increase the risk of experiencing such symptoms. Ecstasy users (at least once in the last 12 months) who subsequently took ecstasy (n=35) over the period of one week, were compared on measures of mood, sleep, stress and drug use, with those who abstained from ecstasy (n=21) that week. Measures were administered the week prior to ecstasy use and one and three days following use, or the equivalent day for abstainers. Mood symptoms were assessed using the Kessler-10 self-report psychological distress scale, a subjective mood rating (1-10), and using the depression, anxiety and hostility items from the clinician-rated Brief Psychiatric Rating Scale.
