Brief Summary
This study investigates whether MDMA may have a pain-reducing effect. The effect of MDMA is compared with a placebo (a substance with no active effect). In the study, moderate pain will be artificially created in healthy participants using repeated small electrical pulses applied under the skin. At the same time, participants will take MDMA or a placebo by mouth. This allows researchers to compare how MDMA affects the artificially created pain. A total of 20 healthy volunteers will take part in this study.
