Poster summary

Psychedelics have been investigated as psychosis model and therapeutic models. We sought to explore these models and their potential relationship. In a randomized, double-blind, placebo-controlled, crossover design, 24 healthy volunteers received 50 μg D-lysergic acid diethylamide (LSD) or inactive placebo. We assessed psychotic-like experiences (Aberrant Salience Inventory), therapeutic potential (Creative Imagination Scale; Five Facet Mindfulness Questionnaire; Mindful Attention Awareness Scale; Experiences Questionnaire), and psychedelic experience (Altered State of Consciousness, Mystical Experiences, and Challenging Experiences Questionnaire; Ego-Dissolution Inventory). LSD induced psychedelic experiences (alteration of consciousness, mystical experiences, ego-dissolution), increased aberrant salience and suggestibility, but not mindfulness. LSD-induced aberrant salience correlated with mystical experiences. The LSD state resembles a psychotic experience and offers a healing tool. The link between psychosis and therapy model might lie in mystical experiences. The results suggest an importance of meaning attribution for the psychosis model and that psychedelic-assisted therapy should better explore therapeutic suggestions fostering mystical experiences.
