Current and former ecstasy users report different sleep to matched controls: a web-based questionnaire study
This study sought to test the association between ecstasy use and abnormal sleep.
An anonymous web-based questionnaire containing questions on drug use and sleep was completed by 1035 individuals. From this large sample, a group of 89 ecstasy users were found who reported very little use of other drugs.
This ”ecstasy-only“ group was further divided into two groups of 31 current users and 58 abstinent users. The subjective sleep of current and former ecstasy-only users was compared with that of matched controls. Patients were asked to rate their sleep according to:
1) sleep quality
2) sleep latency
3) night time awakenings
4) total sleep time.
Current ecstasy-only users reported significantly worse sleep quality (P < 0.05) and a greater total sleep time (P < 0.001) than controls. It was inferred that these differences might be due to recovery from the acute effects of the drug. Abstinent ecstasy-only users reported significantly more nighttime awakenings than controls (P < 0.01). These subjective findings are in agreement with the objective findings of previous studies showing persistent sleep abnormalities in ecstasy users.
