Rick Strassman’s DMT Studies — Entity Reports and Later Dimensional Interpretation (1990–2026)

An X post of 2 September 2026 claims that DMT is a ‘key to other dimensions’ and that Rick Strassman found such consistent reports of external beings in separately tested people in 1995 that he ended the research in alarm. The documented research record is narrower. In 1994, Strassman and colleagues at the University of New Mexico published a clinical IV dose-response study: two open doses followed by a randomized, double-blind, saline-placebo-controlled phase in twelve experienced volunteers. It documented dose-related, rapidly emerging subjective DMT effects that mostly resolved within about 30 minutes and the Hallucinogen Rating Scale. Its abstract reports no finding establishing independent entities, another dimension, or a fear-driven research termination. UNM dates Strassman’s DMT and psilocybin research to 1990–1995. A professional book review identifies several practical and ethical factors for a subsequent research phase that did not proceed, rather than a shutdown triggered by ‘proven’ entities. Later studies do document recurring report and interpretation patterns: Davis et al. surveyed 2,561 people about a memorable inhaled-DMT entity encounter, while Lawrence et al. found entity reports in 45.5% of 3,778 analyzed r/DMT self-reports. Those studies measure subjective phenomenology, memory, and worldview interpretation; they do not test for an external independently existing entity. In 2026, Mago et al. explicitly propose a neurocomputational account while taking no position on the ontology of entities and also discuss cultural and contextual influences. This record therefore documents a genuine research field concerning unusual subjective experiences, but not evidence of dimensional access, UAP/NHI contact, or external beings.
