Naturalistic Study Into the Hangover Effects of MDMA
July 21, 2011 updated by: Utrecht Institute for Pharmaceutical Sciences
A Naturalistic Study Comparing the Hangover Effects of MDMA, Other Drugs, and Alcohol in a Sample of Recreational Polydrug Users
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.
