Examining changes in personality following shamanic ceremonial use of ayahuasca

Abstract The present study examines the association between the ceremonial use of ayahuasca—a decoction combining the Banistereopsis caapi vine and N,N-Dimethyltryptamine-containing plants—and changes in personality traits as conceived by the Five-Factor model (FFM). We also examine the degree to wh...
