Transformative experience and social connectedness mediate the mood-enhancing effects of psychedelic use in naturalistic settings

Proceedings of the National Academy of Sciences January 21, 2020 Matthias Forstmann, Daniel Alexander Yudkin, Annayah Miranda Beatrice Prosser et al. 185 citations

Using psychedelic substances such as LSD or psilocybin is linked to improved mood and stronger feelings of social connectedness in naturalistic settings. Across six multiday mass gatherings in the United States and the United Kingdom, over 1,200 participants were studied. Those who had taken psychedelics reported higher positive mood, an effect that occurred sequentially through transformative experiences and then increased social connectedness. The association was strongest for people who had used psychedelics within the previous 24 hours compared to the past week. The findings provide robust evidence that psychedelic use can have positive affective and social consequences in real-world contexts.

Differential effects of MDMA and methylphenidate on social cognition

Journal of Psychopharmacology July 22, 2014 Yasmin Schmid, Cédric M. Hysek, Linda D. Simmler et al. 154 citations

A low dose of MDMA (75 mg) enhanced emotional empathy for positive emotional situations and reduced recognition of sad faces, but did not affect cognitive empathy, social cognitive inferences, or moral judgment. Methylphenidate (40 mg) had no effects on emotional processing, empathy, or mental perspective-taking. MDMA increased subjective feelings of closeness, openness, and trust, along with plasma oxytocin and prolactin levels. These social-cognitive effects likely contribute to MDMA's popularity as a party drug.
