Rick Strassman and his colleagues conducted a five-year-long DMT study at the University of New Mexico in the 1990s. The results provided insight about the quality of subjective psychedelic experiences. In this study participants received the DMT dosage intravenously via injection and the findings suggested that different psychedelic experiences can occur, depending on the level of dosage. Lower doses (0.01 and 0.05 mg/kg) produced somaesthetic and emotional responses, but not hallucinogenic experiences (e.g., 0.05 mg/kg had mild mood elevating and calming properties). In contrast, responses produced by higher doses (0.2 and 0.4 mg/kg) researchers labeled as "hallucinogenic" that elicited "intensely colored, rapidly moving display of visual images, formed, abstract or both". Comparing to other sensory modalities the most affected was the visual. Participants reported visual hallucinations, fewer auditory hallucinations and specific physical sensations progressing to a sense of bodily dissociation, as well as to experiences of euphoria, calm, fear, and anxiety. These dose-dependent effects match well with anonymously posted "trip reports" online, where users report "breakthroughs" above certain doses. These "breakthrough" experiences often result with the user becoming completely or almost completely detached from reality (especially visually and audibly), and thrust into "DMT hyperspace". It is here that most users report contact with entities, while even doses slightly under a breakthrough dose have far less extreme effects.
