Here we report a new study examining the relationship between self-reported Ecstasy use and traces of MDMA found in hair samples. &lt;i&gt;Methods:&lt;\/i&gt; 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. &lt;i&gt;Results:&lt;\/i&gt; Self-report of Ecstasy use and presence in hair samples were consistent (p &lt; 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. &lt;i&gt;Conclusion:&lt;\/i&gt; 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.<\/jats:p>","DOI":"10.1159\/000321833","type":"journal-article","created":{"date-parts":[[2010,10,20]],"date-time":"2010-10-20T07:30:05Z","timestamp":1287559805000},"page":"15-21","source":"Crossref","is-referenced-by-count":39,"title":["Hair
