Abstract
Research on the relationship between personality and psychedelics use has found evidence of a two-way influence where the personality structure predicts individual responses to psychedelics, and psychedelics use results in lasting changes to the individual’s personality structure. This study used brief personality measures in the form of the Ten-Item Personality Inventory (TIPI) and a simplified version of the Risk Taking Index (RTI) in order to measure personality traits in a sample of psychedelics users (N = 319). The participants in the study scored consistently higher than norms on each of the Big Five traits except Extraversion, and on every dimension of risk taking in the RTI. In multivariate logistic regression analyses, personality structure was associated with characteristics of the psychedelic experience that included the feelings of fear, love, and peace as well as states of perceived contact with non-ordinary beings and transcendent forces.
