Exogenous DMT-like psychedelic effects are in essence similar to subjective reports provided after clinical death and near death experiences. Strassman (2001) believes DMT to be very likely involved in the dying process. Similarly, ayahuasca and similar DMT-containing mixtures have been proposed as treatments for a variety of psychiatric disorders and ayahuasca is mostly well-tolerated. The following paragraphs will summarize evidence for medical applications of ayahuasca for treatment, and the following section will examine research on potential adverse effects of repeated use of ayahuasca. DMT binds to the 5-HT2A receptor with relative high affinity IC50 75 +/- 1 nM (McKenna 1990), yet other psychedelics that lack visual effects have a higher affinity for the 5-HT2A receptor (5-MeO-DMT; 14+/- 1 nM; McKenna et al., 1990). The 5-HT2A receptor seems to be necessary, but is not sufficient to account for the visual phenomenon common of the classic hallucinogens.
Potential Benefits
DMT at high concentrations (10-4 M) yields a 90% inhibition of rabbit lung INMT (Thithapandha, 1972). In addition, the same tissues that contain INMT also contain enzymes that metabolize DMT. Only a small fraction of DMT made intracellularly is actually released into the blood. This process helps explain the inconsistent detection levels assessed in many studies https://sober-house.net/easy-ways-to-read-drug-test-results-10-steps-with/ discussed below (Karkkainen et al., 2005; Barker et al., 2012; see endogenous section). DMT production is increased under stress in rodent brain and adrenal gland (Christian et al, 1977; Beaton and Christian, 1977). Whether the stress-induced mechanism for increasing DMT is due to increasing INMT activity, or a decrease in DMT metabolism remains unknown.
Long-term effects
Α-ET may produce serotonin neurotoxicity [66] but the exact mechanism is not understood. Serotonin neurotoxicity was produced by the combined administration of a non-neurotoxic serotonin releasing agent and the dopamine releasing agent S-amphetamine [67]. Other authors added that α-ET was the first tryptamine derivative, indeed, the first non-phenylisopropylamine, shown to produce stimulus effects similar to those of MDMA on unconditioned motor behavior in rats [62,68]. Like α-MT, other simple synthetic tryptamines, such as α-ET, possess a methyl group on the alpha carbon, providing protection from MAO metabolism [56]. Rick Strassman pioneered contemporary research into psychedelics in the 1990s with the belief that their profound effect on consciousness warranted further exploration. He published several landmark studies including detailed dose-response experiments using the Hallucinogen Rating Scale to measure subjective experiences.
- When DMT was given repeatedly to human volunteers (4 times at 30 min intervals), tolerance to the increases in various endocrine levels was observed, including corticotropin, prolactin and cortisol (Strassman, et al., 1996).
- Effects include auditory, visual and time perception distortions, emotional experiences, memory impairment, asthma (12%), high blood pressure (9%) and chronic fatigue syndrome (8%) [47].
- The DMT-containing plant market is always changing, so keep an eye out for new appearances.
- It can also have a yellow, pink, or orange hue when not in its purest form.
- Inadequate solubility and lack of increased pharmacological effects limits IV administration [56].
How fast the body metabolizes DMT
If DMT does increase interferon secretion, it may be beneficial in contributing to or aid in better elimination of malignant and/or infected cells. DMT-induced EEG activation in rabbits can be antagonized by neuroleptics (DA receptor blocking compounds (Moore et al., 1975). For example, DMT releases dopamine from presynaptic stores (Smith, 1975).
Measureable concentrations seem to only occur intermittently (Oon et al., 1977), and exact tissue source or sources of DMT is still unclear. It is commonly thought that the adrenal gland and lungs are the most common places for the highest amount of DMT production, since this is where highest levels of INMT have been reported (Thompson and Weinshillboum, 1998; Thompson et al., 1999). It is likely that most adverse effects of hallucinogens are psychological effects, such as intense fear, https://sober-house.org/alcohol-and-rage-what-you-need-to-know/ paranoia, anxiety, grief, and depression, that can result in putting the user or others in physical harm or danger (Carbonaro et al., submitted). Anecdotal reports describe psychologically challenging experiences with DMT and other psychedelic compounds. The rates of occurrence for these effects have not been properly accounted for. However, in the case of psilocybin, about 30% of laboratory experiences include psychologically challenging experiences (Carbonaro et al, submitted).
Toxicological information is still scarce but users suggest the oral dose is 75–150 mg but no duration of effects was reported. The effects include euphoria, visual distortions and difficulty in sleeping. At low dosages (15–30 mg orally, 5–20 mg smoked), 5-MeO-α-MT produces https://sober-home.org/a-potential-case-of-acute-ketamine-withdrawal/ powerful hallucinations [60]. Depending upon the individual, negative effects, including death, are more typical at higher dosages (80–100 mg oral 5-MeO-α-MT) [6,59]. Neurologic manifestations that may occur include agitation, restlessness, confusion and lethargy.
DMT shares psychedelic and hallucinogenic activity with lysergic acid diethylamide (LSD) and mescaline in terms of intensity and characteristics [22]. Common routes of DMT administration are oral, insufflation, intravenous (IV) and smoking [24]. The time course of DMT administered via inhalation of vaporized freebase or IV injection of a water-soluble salt is brief. The onset is rapid, with full effects noted within 2 min of administration and subjective effects fully resolving within 20–30 min [25]. Szára et al. also reported a rapid onset (2–5 min) of effects and a duration of action of 30–60 min following intramuscular (IM) administration of 0.2–1 mg/kg DMT [26].
DMT, like these other classic psychedelics, is a serotonin 2A receptor agonist, which means it binds to these receptors and induces neurochemical shifts that alter sensory perceptions, cognitive processes, and other brain functions related to consciousness. Research in the journal Nature Scientific Reports has found that it not only alters the brain’s chemistry, but it also shifts the brain’s electrical activity in ways that map onto people’s psychedelic experiences. In other words, a user’s trip seems directly tied to these brain changes.
Asymmetries in cross-substitution (i.e., compound A substitutes for compound B, but compound B does not substitute for compound A) can indicate that the two compounds may have overlapping, but not identical mechanisms of action (e.g., Grant, 1999). Drug discrimination can be useful in investigating potential mechanisms of action of the trained discriminative stimulus by utilizing selective agonists and antagonists to either mimic or block the effects. Subsequent paragraphs will examine discrimination studies assessing potential mechanisms of action of DMT. Endogenous DMT is synthesized from the essential amino acid tryptophan, which is decarboxylated to tryptamine.
Recently identified as “the drug of choice for the age of kale,” the popularity of ayahuasca looks set to grow as a new generation of spiritual seekers commune with this ancient plant medicine. DMT trippers often share reports of being ripped from their bodies, hurtling through space at the speed of light, and journeying into hidden dimensions. “One’s sense of self is usually maintained, time and space perception are generally maintained, and one can usually direct one’s will and attention toward the contents of the experience,” explained Strassman. When leaves containing DMT are brewed in a sacred tea known as ayahuasca, the drug becomes profound plant medicine.
