Scientists test if psychedelics make people nicer

This study aimed to understand if drugs that affect brain chemicals like serotonin (found in psychedelics like MDMA and psilocybin) can cause lasting positive changes in how people behave socially. Researchers gave different substances to 122 healthy adults and measured things like empathy, generosity, and social connection weeks later. The goal was to see if these effects are unique to psychedelics or if other stimulant drugs could produce similar results.
