MDMA increases generosity, but the effect depends on the recipient's social closeness. In two studies, participants decided whether they or another person would receive money. Without MDMA, people were more generous toward close friends than acquaintances or strangers; generosity was linked to household income and the personality trait Agreeableness. After a high dose of MDMA (1.0 mg/kg), generosity increased only toward a friend. A lower dose (0.5 mg/kg) slightly increased generosity toward a stranger, especially among women. The findings suggest MDMA's prosocial effects are selective, similar to oxytocin, and depend on relationship proximity.
