Abstract

As psilocybin awaits approval by the Food and Drug Administration (FDA), scholars debate whether psychedelic-assisted psychotherapy should be required when prescribing this medicine. Here, we report the case of a patient who underwent a psilocybin experience without psychedelic-assisted psychotherapy, resulting in inpatient psychiatric admission. This case underscores the importance of taking psilocybin in controlled clinical settings. Moreover, we discuss how psychedelic-assisted psychotherapy could have altered the outcome of her experience and the role of experiential learning in psychedelics for potential prescribers.
