What it is testing

Summary

The aim of the study is to compare hangover effects of MDMA users versus those who used other drugs, or alcohol only at New Year's Eve. The week after New Years Eve, every day participants complete a questionnaire about the presence and severity of potential hangover symptoms. At day 1, demographics and alcohol and drug use at New Years Eve were recorded. On day 7, the Brief Symptom Inventory (BSI) is completed to asses last weeks mood. After 4 weeks, after a drug-free week, the BSI is completed again to serve as a reference.
