Although several studies and reports have shown the potential analgesic use of serotonergic psychedelics in cancer pain, phantom limb pain and cluster headache, evidence supporting their use for chronic pain is still limited. The past years have seen a considerable renewal of interest toward the therapeutic use of these compounds for mood disorders, resulting in a marked increase in the number of people turning to psychedelics in an attempt to self-medicate a health condition or improve their wellbeing. In western countries particularly, this population of users overlaps substantially with chronic pain sufferers, representing a unique opportunity to evaluate the effects these compounds have on pain and wellbeing. Here, we report results from an online survey conducted between August 2020 and July 2021 in a population of 250 chronic pain sufferers who had experience with psychedelics, either in microdoses (small sub-hallucinogenic doses), macrodoses (hallucinogenic doses), or both. Macrodoses, while less often used for analgesic purposes than microdoses, were reported to induce a higher level of pain relief than both microdoses and conventional pain medications (including opioids and cannabis). Although the effects were weaker and potentially more prone to expectation bias than with macrodoses, our results also suggested some benefits of psychedelics in microdoses for pain management. The reported analgesic effect appeared unrelated to mood improvements associated with psychedelic use, or the advocacy of psychedelic use. Taken together, our findings indicate interesting potential analgesic applications for psychedelics that warrant further clinical research.
Creativity, that is the creation of ideas or objects considered both novel and valuable, is among the most important and highly valued of human traits, and a fundamental aspect of the sciences. Dreams and hypnagogic states have been highly influential in promoting scientific creativity and insight, contributing to some important scientific breakthroughs. Phenomenologically, the latter states of consciousness share a great deal of overlap with the psychedelic state, which has also been associated with facilitating scientific creativity on occasion. The current article proposes that the dream, hypnagogic and psychedelic states share common features that make them conducive to supporting some aspects of scientific creativity and examines the putative underlying neurophenomenological and cognitive processes involved. In addition, some notable occurrences of scientific insights that have emerged from these types of altered states are reviewed and shared common features are presented, providing a ground for future research. The psychedelic state may have its own characteristic features making it amenable to creativity enhancement, such as brain hyperconnectivity, meta-cognitive awareness, access to a more dependable and sustained altered state experience, and potential for eliciting sustained shifts in trait openness. The contextual factors which may contribute to enhancement of scientific creativity and insight will be evaluated. While research in this area is limited, further work to elucidate how psychedelics may best contribute to scientific creativity enhancement is warranted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
