The oxytocin hormone, which is triggered by MDMA, is often described as the “love hormone” or “cuddling chemical,” but there might be a darker side to it.
In the study, professor of psychology at the University of Amsterdam Carsten de Dreu found that the loved-up feeling you get after taking MDMA, or being flooded with oxytocin, only extends to your “in-group.”
Oxytocin, he said, “motivates in-group favoritism” and “derogation” of outsiders. He added that it had “a role in the emergence of intergroup conflict and violence.”
