The Association of Classic Serotonergic Psychedelic Use and Intention of Future Use with Nature Relatedness

Journal of Psychoactive Drugs August 19, 2022 Marcio S. C. Longo, Bheatrix Bienemann, Marco Multedo et al. 10 citations

People who currently use ayahuasca/DMT, psilocybe mushrooms, LSD, cannabis, or MDMA/ecstasy score higher on nature relatedness than those who have never used these substances. After accounting for sociodemographic factors, only current and past use of ayahuasca/DMT remained positively associated with nature relatedness. Among those who reported an intention to use psilocybe mushrooms in the future, that intention was also linked to higher nature relatedness. The findings suggest that classic serotonergic psychedelics may have a unique relationship with nature relatedness, but the cross-sectional design cannot establish causation.

Adaptation and latent structure of the Brazilian version of the Ego Dissolution Inventory (EDI-BR): an exploratory study

Trends in Psychiatry and Psychotherapy October 18, 2022 Bheatrix Bienemann, Mariana Ridolfi, Marco Multedo et al. 5 citations

A validated scale for measuring ego dissolution demonstrated strong psychometric properties, though its factor structure may differ from the English version. Because validation is an ongoing process, further studies should compare ego dissolution scores across different substances and regions of the country.
