Subsequent paragraphs will examine discrimination studies assessing potential mechanisms of action of DMT. More recently, Jacob and Presti (2005) proposed that endogenous DMT may have an anxiolytic role based on the reported subjective effects of DMT administered in low doses, which would result comparable concentrations and biological actions to those of endogenous DMT. Sensory alterations commonly described by people taking DMT occur only when relatively high concentrations of DMT are administered. These high concentrations are similar to those observed in the synapse when endogenous DMT is released (review, Wallach, 2009). Rick Strassman pioneered contemporary research into psychedelics in the 1990s with the belief that their profound effect on consciousness warranted further exploration.

  1. Finally, 88% of patients achieving a peak mystical experience experienced remission, while only 28% of patients experienced remission without a peak experience.
  2. Ayahuasca is tea made from plants containing N, N-dimethyltryptamine, usually a mixture of Psychotria viridis and Banisteriopsis caapi.
  3. At best, sigma-1 receptors may partially mediate the subjective effects of DMT (see review by Su et al., 2009).
  4. As DMT exists naturally in so many plant species it can therefore be extracted and isolated from various plants and plant tissues.

Human consumption

Progress in hallucinogen research in these areas has been slowed due to over-regulation. Given the endogenous nature of DMT, it deserves a special status for future research. Recent research has demonstrated that DMT is present in and is released from the pineal gland of live, freely-moving crack addiction rodents. New receptors for DMT have been identified and a potential role for DMT as a neuroprotectant and/or neuroregenerative agent has been suggested. Hallucinogens have been shown to produce brain patterning resembling dream states, apparently mediated through 5-HT2A receptor activation.

More recent studies have examined the effects of DMT on various experimental models of changes in cognition in schizophrenic patients. Normal subjects are administered DMT and given various cognitive tasks to perform during fMRI scans. Subsequent research reported that levels of endogenous DMT increased in schizophrenic patients during psychotic episodes, which declined as their state improved (Checkley et al., 1980; Murrary et al., 1979). However, no changes in DMT levels were observed in rapidly cycling states (manic-depressive) (Checkley et al., 1980). These findings renewed interest in the transmethylation hypothesis, which states that schizophrenia may be due to stress-induced production of psychotomimetic methylated derivatives of catecholamines or indolealkylamines in the brain. DMT seems to fits the bill as it is an indolealkylamine, is an endogenous compound, and is linked to stress reactivity (see reviews by Myin-Germys and van Os, 2007; Grammenos and Barker, 2015).

“DMT is produced in the pineal gland and released when you die/have a near-death experience”

These data became the foundation for several hypotheses that any neuropharmacological effects of endogenous DMT must lie in its formation in the periphery and its subsequent transport into the brain. This idea was strengthened by the fact that DMT has been shown to be readily, and perhaps actively, transported into the brain (Cozzi et al., 2009). However, the data concerning the apparent absence of INMT in brain would appear to be in conflict with the many earlier studies that demonstrated both in vivo and in vitro biosynthesis of DMT in the brain. Perhaps the science behind the discovery of endogenous opioids offers us a corollary. With the discovery of the endogenous hallucinogen N, N-dimethyltryptamine (DMT, 1, Figure ​Figure1),1), perhaps, as with the endogenous opioids, we have a similar opportunity to understand perception and consciousness. Recent research has stimulated a renewed interest in further study of this compound as a neuro-regulatory substance and, thus, a potential neuro-pharmacological target.

Interactions with other drugs

In large enough doses, DMT can give you a « high » and distort your senses so that you see or feel things that aren’t really there. Other names for DMT are Dimitri, businessman’s special, the spirit molecule, and elf spice. It is an endogenous compound in animals (Saavedra and Axelrod, 1972; Christian et al., 1977, Hollister, 1977) and in a wide variety of plants found around the globe.

In terms of pursuing future research on the presence of the endogenous indolealkylethylamines, further studies are necessary to determine whether MDMT actually exists in humans. Similarly, there are no data on the possible presence of HDMT in CSF although it has been routinely identified in urine (Barker et al., 2012). Future analyses to determine endogenous N, N-dimethyl-indolethylamines should also include a search for their major metabolites. The methodology applied in such analyses must include rigorous 2c drug effects of 2c validated protocols for sample collection, storage, extraction and analyte stability and appropriate criteria for unequivocal detection and confirmation of the analytes using validated methods. Modern exact-mass liquid chromatography-mass spectrometry instrumentation should be the analytical method of choice. Such capabilities may then be applied to address the many variables that may influence the ability to measure DMT and/or its precursors and metabolites (Figure ​(Figure2)2) in the periphery.

Historical Research and Clinical Trials

Such a determination may prove fruitful since a preliminary examination for the possible colocalization of INMT and AADC in the brain is supported by the data provided in the Allen Brain Atlas, mapping INMT and AADC gene expression (brain-map.org). Single doses of DMT produced rapid onset of marked sympathomimetic effects including increased heart rate and blood pressure (Strassman et al., 1994). When a 5-HT1A antagonist, pindolol, was co-administered with DMT, the increase in heart rate was diminished whereas the increase in blood pressure was enhanced (Strassman, 1996). Tolerance to the effects of DMT was tested by administration of DMT to human volunteers four times at 30-min intervals. A progressive decrease in heart rate was observed over the four doses, but not in blood pressure (Strassman, et al., 1996). In contrast, two repeated doses of ayahuasca 4-h apart reduced systolic blood pressure and heart rate (Dos Santos et al., 2012).

Most of the negative side effects tend to come during the ayahuasca experience. It can be physically uncomfortable, nauseating, and in some cases can cause severe mental distress (all part of the process). Your body mostly plops back in its seat and maybe feels a little weird and tingly afterward. It is of interest that the DMT experience has been shown to be not dissimilar to actual reported near-death experiences, wherein people encountered long-dead relatives and even ‘god,’” Barker continued.

However, DMT is subjectively distinct from all other psychedelics with its short-acting and unique characteristics. As with other psychedelics, however, the experience significantly depends on many external variables. These include the ‘set and setting’, mindset of the individual, integration, and preparation, route of administration, dosage, and many other important factors. Different routes of administration may change how effective the drug is and what the experienced effects may be.

These data support the idea that it is, therefore, an endogenous ligand for such receptors and intrinsically involved in serotonergic function. This being the case, there is already a significant body of work regarding DMT’s binding and effects, especially relative to effects on serotonin, acting as a serotonergic modulator. Additional work in this area, while acknowledging DMT as an endogenous ligand, will prove essential. Changes mixing shrooms and alcohol effects and risks ark behavioral health in relevant metabolomic and array profiles following DMT administration will further add to our understanding of its endogenous role. Ayahuasca has been reported to decrease the percentage of CD3 and CD4 lymphocytes, but to increase the number of natural killer cells (Dos Santos et al., 2011). It has been hypothesized that DMT might increase activity of the immune system and could prove useful as a treatment for cancer.

Without more data on the recreational use of this class of compounds, it is not possible to conclude whether the synthetic hallucinogens are indeed more toxic or whether the social context may contribute to the effects. As discussed and delineated above, more research is needed on DMT’s natural role and function and interaction with other neurotransmitter systems. This will require the recommended future research into DMT biosynthesis, metabolism and binding, new methods for peripheral and central detection and data from administration, imaging and therapeutic trial studies. The data derived from the areas of research addressed above will no doubt suggest several possible new avenues for additional future research on DMT. In order to advance, however, regulatory blockades to hallucinogen research must be removed.
