Summary
Psychedelics can profoundly shape personal experiences, influencing behavior and outlook. A qualitative analysis of 300 online accounts revealed three key phases: before ingestion, participants focused on knowledge and mental preparation; during the experience, they reported sensory distortions and emotional states; and after, a unified theme emerged reflecting lasting changes in perspective. Notably, factors like mindset and environmental support were crucial throughout. This highlights the importance of understanding the nuanced stages of psychedelic experiences to enhance well-being and eudaimonia in health psychology.
Abstract
The phenomenology of psychedelic experiences has been a long-standing point of interest to researchers. However, internal experience has been relatively relegated, with much work done on the clinical outcomes of psychedelic therapies. Our reflexive thematic analysis revealed that structurally, people on fora write about their experiences sequentially, considering factors prior to (preparatory), during (acute phase), and after their account of ingesting psychedelics. Themes constructed prior to experience were (1) subjective knowledge and perception of psychedelics, (2) intention and efforts to mentally prepare, and (3) experiential aids. Generated themes during the experience were (1) sensory and cognitive distortions, (2) mindset and affective quality, and (3) environmental stability and support. Experiential impact on behavior and outlook was constructed as the unitary theme following the experience. Future work should look more closely at the role of set and setting within the context of the stages leading up to, during, and after psychedelic administration.
