Ecstasy tested as painkiller in healthy volunteers
NCT ID NCT07494214
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage study explores whether MDMA (the active ingredient in ecstasy) can reduce pain. Twenty healthy volunteers will receive either MDMA or a placebo, while mild pain is created using small electrical pulses under the skin. Researchers will compare pain ratings between the two groups to see if MDMA has a pain-relieving effect.
