“The mushroom was more alive and vibrant”: Patient reports of synthetic versus organic forms of psilocybin

In a program offering psilocybin-assisted therapy for end-of-life distress, participants received synthetic psilocybin, whole Psilocybe cubensis mushrooms, and a mycological extract on separate occasions. Post-treatment interview transcripts revealed broad consensus that all three forms were helpful and similar, generating visual and perceptual distortions, emotional and cognitive insight, and mystical experiences. However, synthetic psilocybin was described as feeling less natural and its overall quality of experience was inferior to the organic forms. These preliminary findings suggest that research should include whole psychedelic mushrooms and extract alongside synthetic psilocybin, given that traditional medicine keepers have used whole mushrooms and plant material for millennia.

Abstract

Abstract Interest in psychedelic research in the West is surging, however, clinical trials have almost exclusively studied synthetic compounds such as MDMA, ketamine, DMT, LSD, ibogaine, and psilocybin. To date, few clinical trials have utilized whole mushroom/plant material like Psilocybe mushrooms, Iboga, or Ayahuasca. Individuals participating in the Roots To Thrive Psilocybin-Assisted Therapy for End of Life Distress program were administered synthetic psilocybin, whole Psilocybe cubensis , and mycological extract on separate occasions and post-treatment interview transcripts were qualitatively analyzed to discern themes and patterns. There was broad consensus that all three forms were helpful and similar, all generating visual and perceptual distortions, emotional and cognitive insight, and mystical experiences. However, synthetic psilocybin was said to feel less natural compared to organic forms, and the overall quality of experience of synthetic psilocybin was inferior to the organic forms. Research should be conducted with whole psychedelic mushrooms and extract in addition to synthetic psilocybin given this preliminary data, especially when considering that medicine keepers around the world have utilized whole mushrooms and plant material for millennia.
