This international, online study (N\u00a0=\u00a0759) sought to investigate the potential acute, subacute, and long-term effects of psychedelic drug use on cognition through cognitive task assessment. Questionnaires assessing mental health and quality of life were also administered.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Participants completed cognitive tasks assessing working memory, selective attention, and visual\/spatial perception, as well as questionnaires assessing mental health outcomes and quality of life.

Lifetime use was not associated with long-term cognitive decline. Recent users reported more depressive and dissociative symptoms, whereas lifetime users reported lower scores. Lifetime users scored lower on psychological and social quality of life domains, indicating possible long-term psychosocial effects.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>These findings highlight the need to differentiate between the acute and long-term effects of psychedelics; lab-controlled, longitudinal studies are needed to enable safe clinical application.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpsyt.2026.1843186","type":"journal-article","created":{"date-parts":[[2026,9,24]],"date-time":"2026-09-24T05:42:37Z","timestamp":1790228557000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of psychedelic drug use on neurocognitive function and the psychological and social domains of quality of life: an international online study"],"prefix":"10.3389","volume":"17","author":[{"given":"Franziska","family":"Stadler","sequence":"first","affiliation":[{"name":"Department of Psychiatry and Psychotherapy, Medical University of Vienna","place":["Vienna, Austria"]},{"name":"Comprehensive Center for Clinical Neurosciences and Mental Health, Medical University of Vienna","place":["Vienna, Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johan","family":"Saelens","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Psychotherapy, Medical University of Vienna","place":["Vienna, Austria"]},{"name":"Comprehensive Center for Clinical Neurosciences and Mental Health, Medical University of Vienna","place":["Vienna, Austria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ioline D.","family":"Henter","sequence":"additional","affiliation":[{"name":"Experimental Therapeutics and Pathophysiology Branch, National Institute of Mental Health, National Institutes of Health","place":["Bethesda, MD, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nathalie M.","family":"Rieser","sequence":"additional","affiliation":[{"name":"Department of Adult Psychiatry and Psychotherapy, Psychiatric University Clinic Zurich and University of Zurich","place":["Zurich, Switzerland"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maximillian S.","family":"Greenwald","sequence":"additional","affiliation":[{"name":"Yale University School of Medicine, The Connecticut Mental Health Center","place":["New Haven, CT, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth D.","family":"Ballard","sequence":"additional","affiliation":[{"name":"Experimental Therapeutics and Pathophysiology Branch, National Institute of Mental Health, National Institutes of Health","place":["Bethesda, MD, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katrin H.","family":"Preller","sequence":"additional","affiliation":[{"name":"Department of Adult Psychiatry and Psychotherapy, Psychiatric University Clinic Zurich and University of Zurich","place":["Zurich, Switzerland"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"Jr.","given":"Carlos A.","family":"Zarate","sequence":"additional","affiliation":[{"name":"Experimental Therapeutics and Pathophysiology Branch, National Institute of Mental Health, National Institutes of Health","place":["Bethesda, MD, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph","family":"Kraus","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Psychotherapy, Medical University of Vienna","place":["Vienna, Austria"]},{"name":"Comprehensive Center for Clinical Neurosciences and Mental Health, Medical University of Vienna","place":["Vienna, Austria"]},{"name":"Experimental Therapeutics and Pathophysiology Branch, National Institute of Mental Health, National Institutes of Health","place":["Bethesda, MD, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,24]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"187","DOI":"10.1089\/psymed.2023.00","article-title":"What is in a name?
