Dmt Crystals (Crystal Dmt)
DMT crystals, or N,N-Dimethyltryptamine, is a psychedelic chemical that occurs naturally in both plants and animals from underwater organisms to land mammals. DMT is also the active hallucinogenic compound in ayahuasca, a tea brewed from the shrub Psychotria viridis used for ritual purposes by indigenous people in the Amazon. See our ayahuasca guide for more on this psychedelic brew.
People also ingest DMT in crystal form, smoking it in a pipe or bong, as well as vaporized. This form of ingestion produces a powerful but short-lasting hallucinogenic state, considered to be one of the most intense psychedelic experiences in existence.
Induced DMT experiences can include profound time-dilation, visual, auditory, tactile, and proprioceptive distortions and hallucinations, and other experiences that, by most firsthand accounts, defy verbal or visual description. Examples include perceiving hyperbolic geometry or seeing Escher-like impossible objects.
Several scientific experimental studies have tried to measure subjective experiences of altered states of consciousness induced by drugs under highly controlled and safe conditions.
Rick Strassman and his colleagues conducted a five-year-long Dmt crystals 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 via intravenous 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 to the user becoming completely or almost completely detached from reality (especially visually and auditorily), 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.
Dimethyltryptamine is primarily a serotonin (5-HT) receptor agonist. Like many other chemicals in its class, DMT’s psychedelic actions can mostly be attributed to its effects on the 5-HT2A receptor. It does affect many other receptor types (including dopamine and sigma receptors), but the consequences of these interactions are not well understood.
In a study that administered low, medium, or high doses to 12 volunteers, the psychedelic threshold for DMT was found to be 0.2 mg/kg. At this level, most biological effects were detectably altered. Adrenocorticotropin hormone, beta-endorphin, prolactin, growth hormone (GH), and cortisol were all elevated. Pupil diameter, heart rate, and blood pressure all peaked within 2 minutes of administration, as did subjective experiences.
A later trial found that the body does not build a tolerance to DMT, meaning there’s no need to take more to repeat the same effects, unlike other psychedelics such as LSD and psilocybin.
