Hair MDMA Samples Are Consistent with Reported Ecstasy Use: Findings from a Study Investigating Effects of Ecstasy on Mood and Memory

Among 49 undergraduate volunteers, self-reported Ecstasy use closely matched MDMA traces found in hair samples. Both self-report and hair analysis predicted lower happiness and higher stress ratings. Self-reported use, but not hair analysis, was also linked to lower tension. The findings suggest the Internet can effectively complement traditional laboratory studies on recreational drug effects.

Abstract

Aims: Our group has conducted several Internet investigations into the biobehavioural effects of self-reported recreational use of MDMA (3,4-methylenedioxymethamphetamine or Ecstasy) and other psychosocial drugs. Here we report a new study examining the relationship between self-reported Ecstasy use and traces of MDMA found in hair samples. Methods: In a laboratory setting, 49 undergraduate volunteers performed an Internet-based assessment which included mood scales and the University of East London Drug Use Questionnaire, which asks for history and current drug use. They also provided a hair sample for determination of exposure to MDMA over the previous month. Results: Self-report of Ecstasy use and presence in hair samples were consistent (p < 0.00001). Both subjective and objective measures predicted lower self-reported ratings of happiness and higher self-reported stress. Self-reported Ecstasy use, but not presence in hair, was also associated with decreased tension. Conclusion: Different psychoactive drugs can influence long-term mood and cognition in complex and dynamically interactive ways. Here we have shown a good correspondence between self-report and objective assessment of exposure to MDMA. These data suggest that the Internet has potentially high utility as a useful medium to complement traditional laboratory studies into the sequelae of recreational drug use.
