Beyond the empathogen label: the social-affective profile of MDMA

PsyArXiv Preprints August 31, 2026 preprint

3,4-methylenedioxymethamphetamine (MDMA) is widely described as an “empathogen”, yet empathy is not a unitary process. Here we review MDMA’s social effects by decomposing them into social perception and emotion discrimination, sociability and social reward, affective sharing, cognitive empathy and mentalizing, and prosocial behaviour. Available evidence gathered in humans and other mammals...
