Relationship Between Naturalistic Psychedelic Use and Grandiose Narcissism: An Online Cross‐Sectional Study

International Journal of Psychology July 14, 2026 Anastasia Ruban, Paweł Orłowski, Michał Bola et al.

ABSTRACT The present study examined the relationship between naturalistic psychedelic use and two distinct forms of grandiose narcissism: admiration and rivalry . Using data from an online survey, we compared psychedelic users ( N = 630), non‐users ( N = 100) and individuals planning to use psychedelics in the future ( N = 141) on levels of admiration and rivalry. Additionally, we explored how...

Psychedelics as Non-Specific Amplifiers

Journal of Anomalous Experience and Cognition October 30, 2025 Anastasia Ruban, Michiel van Elk

Return to the Real describes how culturally prevalent narratives shape psychedelic experience. Building on Ten Berge’s two-part analysis, our commentary argues that psychedelic effects are best understood within cultural feedback loops linking cultural set and setting, individual expectations, experience, and its articulation back into culture. On this view, psychedelics operate primarily as...

Setting the Stage for the Inner Journey: Unraveling the Interplay of Contextual Factors and the Intensity of Ego-Dissolution in Naturalistic Psychedelic Experiences

February 26, 2025 Stanisław Adamczyk, Małgorzata Paczyńska, Anastasia Ruban et al. 1 citation preprint

Psychedelic substances have the potential to induce profound alterations in cognition, emotionality, and sensory perception. The quality and intensity of these subjective effects exhibit high intra- and inter-individual variability, which can potentially be accounted for by the variability in contexts in which psychedelics are used. Therefore, the aim of the present cross-sectional study was to...

Processing of self-related thoughts in experienced users of classic psychedelics: A source localisation EEG study.

Progress in Neuro-Psychopharmacology and Biological Psychiatry January 10, 2025 Anastasia Ruban, Mikołaj Magnuski, Justyna Hobot et al. 1 citation

Psychedelics have gained increasing interest in scientific research due to their ability to induce profound alterations in perception, emotional processing and self-consciousness. However, the research regarding the functioning of individuals who use psychedelics in naturalistic contexts remains limited. Here we aim to explore psychological and neurophysiological differences between...

Naturalistic use of psychedelics does not modulate processing of self-related stimuli (but it might modulate attentional mechanisms): An event-related potentials study.

Psychophysiology August 1, 2024 Paweł Orłowski, Justyna Hobot, Anastasia Ruban et al. 5 citations

Classic psychedelics are able to profoundly alter the state of consciousness and lead to acute experiences of ego dissolution - the blurring of the distinction between representations of self and the external world. However, whether repeated use of psychedelics is associated with more prolonged and permanent modifications to the concept of self remains to be investigated. Therefore, we...

February 3, 2024 Anastasia Ruban, Mikołaj Magnuski, Justyna Hobot et al. 1 citation preprint

Psychedelics have gained increasing interest in scientific research due to their ability to induce profound alterations in perception, emotional processing and self-consciousness. However, the research regarding the short- and long-term impact of using psychedelics in non-controlled, naturalistic contexts remains limited. Here we aim to fill this gap and explore differences between naturalistic...

The use of psychedelics for various purposes was common in different civilizations throughout human history and has been explored scientifically for more than a century. Although the applications of psychedelics show promise in the treatment of various psychiatric and neurological indications, as well as in facilitation of well-being and personal growth, several psychedelic-related risks and...

The relation between naturalistic use of psychedelics and perception of emotional stimuli: An ERP study comparing non-users and experienced users of classic psychedelics

October 9, 2023 Paweł Orłowski, Justyna Hobot, Anastasia Ruban et al. preprint

Previous research indicates that psychedelic substances taken in well-controlled laboratory or therapeutic settings have the potential to decrease negative and increase positive emotional reactivity. However, it is unclear whether similar effects are associated with using psychedelics in less-controlled naturalistic environments. Therefore, in the present study we compared neural markers of...

Naturalistic use of psychedelics is related to emotional reactivity and self-consciousness: The mediating role of ego-dissolution and mystical experiences

Journal of Psychopharmacology August 1, 2022 Paweł Orłowski, Anastasia Ruban, Jan Szczypiński et al. 40 citations

Background: Psychedelics are able to acutely alter emotional reactivity and self-consciousness. However, whether the regular naturalistic use of psychedelics can be linked to more persistent trait-level changes in these domains remains an open question. Aim: To test the hypotheses that (1) using psychedelics is related to higher positive and lower negative emotional reactivity; and (2) an...

September 23, 2021 Paweł Orłowski, Anastasia Ruban, Jan Szczypiński et al. preprint

Background: Psychedelics are able to acutely alter emotional reactivity and self-consciousness. However, whether regular, naturalistic use of psychedelics can be linked to more persistent, trait-level changes in these domains remains an open question.Aim: To test three hypotheses: i) psychedelics use is related to higher positive and lower negative emotional reactivity; ii) psychedelics use is...
