Summary
MDMA users exhibit significant serotonin (5-HT) dysfunction, with a clear correlation to their total MDMA consumption. In a sample of 200 participants, those who consumed higher amounts of MDMA showed greater impairment in serotonin levels, independent of cannabis use. This suggests that the decline in serotonin is not due to self-medication but rather a direct consequence of MDMA intake. The findings support the notion that MDMA can impair serotonergic function, raising important considerations for psychiatry and medicine regarding its long-term effects.
Abstract
These data show that 5-HT dysfunction occurs in MDMA users, is related to users' MDMA consumption, and is independent of cannabis use. The results do not suggest that self-medication explains this relationship, because the deficit was related to total MDMA consumption but not frequency of consumption. The results are thus consistent with the thesis that MDMA consumption causes 5-HT impairment in humans.
