“Subjective effects of different psychedelics and holotropic breathwork: a comparison”.
This presentation will summarize the results of a study on the subjective effects of different psychedelics and holotropic breathwork, specifically looking to the occurrence of mystical experiences, using the States of Consciousness Questionnaire (SCQ), also known as the Peak Experience Profile (PEP). The study will also explore the subjective effects of different psychedelics and holotropic breathwork in different contexts, exploring the possible relevance of the context in order to facilitate a mystical experience. The PEP was originally developed by Walter Pahnke (1963) with the aim of measuring and for the evaluation of the potential single mystical experiences occasioned by psilocybin in the Good Friday experiment.. A modified version of the questionnaire, the States of Consciousness Questionnaire (SCQ) was developed and administered recently by Griffiths et al (2006, 2008, 2011) to conduct a number of studies to characterize the mystical-type effects of psilocybin using double-blind and placebo controlled methodologies. The aim of the present study was to compare the subjective effects produced by different psychedelic compounds and holotropic breathwork, and/or in different contexts. Significative differences were found between the subjective effects produced by different psychedelics, including the occurrence of mystical experiences.
