The paradoxical psychological effects of lysergic acid diethylamide LSD
Open accessAbstract
Background: Lysergic acid diethylamide (LSD) is a potent serotonergic hallucinogen or psychedelic that modulates consciousness in a marked and novel way. This study sought to examine the acute and mid-term psychological effects of LSD in a controlled study. Method: A total of 20 healthy volunteers participated in this within-subjects study. Participants received LSD (75 µ g, intravenously) on one occasion and placebo (saline, intravenously) on another, in a balanced order, with at least 2 weeks separating sessions. Acute subjective effects were measured using the Altered States of Consciousness questionnaire and the Psychotomimetic States Inventory (PSI). A measure of optimism (the Revised Life Orientation Test), the Revised NEO Personality Inventory, and the Peter's Delusions Inventory were issued at baseline and 2 weeks after each session. Results: LSD produced robust psychological effects; including heightened mood but also high scores on the PSI, an index of psychosis-like symptoms. Increased optimism and trait openness were observed 2 weeks after LSD (and not placebo) and there were no changes in delusional thinking. Conclusions: The present findings reinforce the view that psychedelics elicit psychosis-like symptoms acutely yet improve psychological wellbeing in the mid to long term. It is proposed that acute alterations in mood are secondary to a more fundamental modulation in the quality of cognition, and that increased cognitive flexibility subsequent to serotonin 2A receptor (5-HT 2A R) stimulation promotes emotional lability during intoxication and leaves a residue of ‘loosened cognition’ in the mid to long term that is conducive to improved psychological wellbeing.

Reported concerns for psychedelic treatment of personality disorders include risk of emotional instability during sessions, challenges to establishing therapeutic rapport, and difficulty integrating psychedelic experiences.
“Additional reported concerns include the risk of emotional instability during sessions, challenges to establishing therapeutic rapport, and difficulty integrating psychedelic experiences (17–19).”
From Psychoanalytically informed MDMA-assisted therapy for pathological narcissism: a novel theoretical approach (2025) · cites this paper as [19]
The Introduction (page unavailable) reports strong or extreme fear during a psychedelic experience and psychological discomfort during acute sessions, supporting the concern about emotional instability. The cited paper does not address difficulty establishing therapeutic rapport or integrating experiences, and it does not examine psychedelic treatment of personality disorders. (LLM, conf=0.86)
Experimental — accuracy not yet measuredRecent research found changes in Openness to experience weeks after an LSD experience.

Psychedelics have been repeatedly found to enhance mindfulness capacities.
“A further psychological process which may be of particular salience when discussing therapeutic efficacy for anxiety, and which psychedelics have been repeatedly found to enhance, are mindfulness capacities (10, 22, 23, 42–46).”
From Decreases in State and Trait Anxiety Post-psilocybin: A Naturalistic, Observational Study Among Retreat Attendees (2022) · cites this paper as [10]
The Results and Discussion report increased optimism and openness two weeks after LSD, but neither identifies these as mindfulness capacities. A search for mindfulness and mindful awareness found no passage in our copy stating that psychedelics enhance mindfulness. Page numbers were not available in the indexed passages. (LLM, conf=0.74)
Experimental — accuracy not yet measuredHallucinogens increase the personality trait openness.
“While it has repeatedly been shown that hallucinogens increase the personality trait openness (85, 86), experimental studies investigating the long-term effects of entactogens and hallucinogens on social cognition and behavior remain scarce.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
