A qualitative analysis of the psychedelic mushroom come-up and come-down

Abstract Psychedelic therapy has the potential to become a revolutionary and transdiagnostic mental health treatment, yielding enduring benefits that are often attributed to the experiences that coincide with peak psychedelic effects. However, there may be an underrecognized temporal structure to th...

description Abstract Psychedelic therapy has the potential to become a revolutionary and transdiagnostic mental health treatment, yielding enduring benefits that are often attributed to the experiences that coincide with peak psychedelic effects. However, there may be an underrecognized temporal structure to this process that helps explain why psychedelic and related altered states of consciousness can have an initially distressing but ultimately distress-resolving effect. Here we present a qualitative analysis of the self-reported ‘come-up’ or onset phase, and ‘come-down’ or falling phase, of the psychedelic experience. Focusing on psilocybin or psilocybin-containing mushroom experience reports submitted to Erowid.org, we use phenomenological, thematic content and word frequency analysis to show that the come-up is more often characterized by negatively valenced feeling states that resemble an acute stress reaction, while the come-down phase is more often characterized by positively valenced feeling states of the sort often observed following recovery from illness or resolution of stress. The therapeutic and theoretical relevance of these findings are discussed.
