Psychological and physiological effects of extended DMT PMC

The chemical typically exists in pure form as a white or yellow/brown crystallized powder with a very distinct smell. “For DMT to be orally active, it must be combined with a monoamine oxidase inhibitor (MAOI), such as occurs in ayahuasca, so the breakdown of DMT in the gut is inhibited long enough for psychoactive blood levels of DMT to occur. DMT has also developed a reputation as “the spirit molecule” because it is believed to be the only psychedelic produced by the body. Some scientists even argue that the drug may be the driving force behind reports of alien abductions, encounters with angels, or near-death experiences. DMT is known for giving users a very intense ‘trip’ – the name given to the experience of taking psychedelic drugs.

Limited data on the effects of DMT suggest that the drug doesn’t produce any significant comedown effects. Increased heart rate and blood pressure can be particularly dangerous if you already have high blood pressure or any kind of heart condition. Healthline does not endorse the use of any illegal substances, and we recognize abstaining from them is always the safest approach. DMT is a functional analog and structural analog of other psychedelic tryptamines such as O-acetylpsilocin (4-AcO-DMT), psilocybin (4-PO-DMT), psilocin (4-HO-DMT), O-methylbufotenin (5-MeO-DMT), and bufotenin (5-HO-DMT). Parts of the structure of DMT occur within some important biomolecules like serotonin and melatonin, making them structural analogs of DMT.

DMT: The key ingredient in ayahuasca

DMT, like other tryptamine hallucinogens, but not phenethylamines, inhibits dorsal raphe cell firing. This mechanism is hypothesized to be an underlying basis of psychedelic-like effects (Aghajanian et al., 1970), which may be mediated by stimulation of 5HT1A somatodendritic receptors (Sprouse and Aghajanian, 1987; 1988). Waking reality is created in a similar way to altered states except that the normal state correlates with event in the “physical” world.

How does it make people behave?

Although marijuana doesn’t always produce hallucinogenic effects, it can do so at high doses. DMT has become of interest because when ingested, it causes brief, episodic visual hallucinations at high concentrations (Stoff et al. 1977; Strassman and Qualls, 1994; Strassman et al., 1994, Shulgin and Shulgin, 1997). DMT is a powerful drug that produces a range of short-lived psychological and physical side effects. LMM analysis revealed significant increases on the 5D-ASC subscales ‘Oceanic boundlessness’ and ‘Visual restructuralization’ for all doses compared with placebo.

1. In another study in humans, 0.16% of DMT (injected intramuscularly) was recovered as DMT following a 24-hour urine collection, (Kaplan et al., 1974).
2. DMT could have serious adverse consequences for users with pre-existing psychological problems or a mental illness, such as schizophrenia.
3. As with the physical effects, the psychological effects of DMT vary from person to person and depend on the same factors.
4. 1956 | The first scientific publication showing the effects of DMT was published by Dr. Szara when DMT was administered to 20 healthy participants (his physician co-workers!).

What about bad trips?

There were significant increases for Dose 2, 3 and 4 compared with placebo on the 5D-ASC subscale ‘Dread of ego-dissolution’, and for Dose 2 and 3 compared with placebo on the 5D-ASC subscale ‘Auditory alterations’. For the 11D-ASC, LMM analysis showed significant increases on the subscales ‘Unity’, ‘Meaning’, ‘Spiritual experience’ ‘Blissful state’, ‘Insightfulness’, ‘Complex imagery’, and ‘Elementary imagery’ for all doses compared with placebo. Additionally, there were significant increases for Dose 3 compared ecstasy mdma: uses effects risks with placebo on the subscale ‘Disembodiment’, and significant increases for Dose 2 and 3 compared with placebo on the subscale ‘Impaired cognition’. No significant differences between any dose and placebo were found for the subscales ‘Anxiety’ and ‘Audio/visual synaesthesia’. Lastly, LMM analysis revealed significant increases in the MEQ-30 total as well as all subscales for all doses with respect to placebo. Results are shown in Figure 2, and summary statistics can be found in Supplemental Tables S4–S6.

Drug Addiction Treatment Levels of Care

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 discussed below (Karkkainen et al., 2005; Barker et al., 2012; see endogenous section).

People have used hallucinogens for religious and healing rituals for centuries. Healthcare providers don’t consider any amount of psychedelic drug use safe. However, scientists are now looking into the possibility of using certain hallucinogens as provider-supervised treatments for mental oxycodone uses, side effects, dosages, precautions health conditions, including depression and anxiety. DMT does bind to 5-HT1D receptor (Hamik and Peroutka, 1989; Heuring and Peroutka 1987; Pierce and Peroutka 1989) and 5-HT3 receptor (Carbonaro, unpublished data), however little has been investigated to follow these results up.

Generally, the effects of inhaled, snorted, or injected DMT last for about 15 to 60 minutes. It typically takes longer to feel the effects of DMT is drinking it in a brew. Synthetic DMT usually comes in the form of a white, crystalline powder. The DEA reports that the drug is still encountered as an illicit drug in instances where it is purchased or manufactured illegally and marketed with other hallucinogens. Young adults aged 19 to 30 make up the largest group of people in the United States to use hallucinogens such as DMT.

DMT infusions induced sustained effects of ‘Immersion’, ‘Entity encounters’ and ‘Visual imagery’, while ‘Ego-dissolution’ remained low across doses. Participants experienced minimal ‘Ego dissolution’ following the DMT infusions in this study (Figure 3). To keep infusion rates equal across doses, DMT was drawn into syringes for the bolus and slow-rate infusion, then saline was added to create a total of 5 ml and 15 ml, respectively.

The latter contains DMT while the former contains MAOIs, which prevent certain enzymes in your body from breaking down DMT. Many South American cultures use ayahuasca in religious and spiritual ceremonies and have done so for centuries. DMT is a Schedule I controlled substance in the United States, which means it’s illegal to make, buy, possess, or distribute it. Some cities have recently decriminalized it, but it’s still illegal under state and federal law. Therefore, it is unclear if DMT use alone can result in a potential fatality. However, individuals who are under the influence of hallucinogenic drugs run the risk of becoming involved in accidents or making judgment errors that can be seriously dangerous and/or fatal.

Large doses of ayahuasca 50-fold higher than typical ritual doses (approx. 15 mg/kg DMT) were fed to pregnant rats. No lethality was observed, but increased incidence of cleft palate and skeletal malformations was observed in their pups (Gardner et al., 2014). 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.

(SPL026 phase IIA trial in major depressive disorder – small pharma 2023). One specific agent that must be avoided with DMT is Lithium because it may lead to seizures and potentially even death. “There is a large body of anecdotal evidence that suggests taking (lithium) with psychedelics significantly increases the risk of psychosis and seizures. As a result, this combination is strictly discouraged.” (PsychonautWiki, 2023). A recent study indicated that one out of three patients on lithium who took psilocybin (also a classical tryptamine psychedelic) experienced a seizure.

Specifically, in terms of categorizing this chemical, DMT is one of the four classical psychedelics, along with LSD, mescaline, and psilocybin. These compounds are considered the world’s most historically significant and most commonly used psychedelic substances. Tryptamines are naturally occurring compounds found in certain plants and animals. Evidence shows that DMT is produced in mammalian brains, but research has not yet confirmed the presence of DMT in the human brain. Although sources such as SAMHSA report that many individuals who misuse hallucinogens typically stop using them on their own without formal treatment, the development of any substance use disorder represents a potentially serious mental health disorder.

Using DMT with other hallucinogens like LSD or magic mushrooms can make an already strong trip even more intense. Before using DMT, it’s important to know how it interacts with other substances. Hallucinogens also carry a small risk of persistent psychosis and hallucinogen persisting perception disorder (HPPD), according to the National Institute on Drug Abuse. Taking a higher dose increases your chances of a bad experience, as does using DMT if you’re in a negative frame of mind. Don’t take DMT with other drugs, recreational or prescription, or mix with alcohol. You don’t develop increased tolerance to the drug with repeated use, and there don’t seem to be any withdrawal symptoms if you stop taking it.

The answer may provide clues to the ability of psychedelic drugs to facilitate behavioural change. Studies have shown that they can be useful in the treatment of addictive or compulsive behaviours. They have a formidable record of safe experimentation with psychedelics, thanks to previous high-profile work with LSD and psilocybin. So securing permission to do the study was “quite a smooth process,” according to Carhart-Harris. But Carhart-Harris and Timmermann hope they will be able to draw some conclusions from the research – one of which will rationalise psychedelic encounters with entities. “I have experienced DMT seven times in the form of ayahuasca across two weeks.

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). Long-term use of DMT-containing beverages may be of more concern as 14-day exposure to ayahuasca in rats altered the structure of the aorta, leading to a thickening of the walls of the aorta relative to the lumen diameter (Pitol et al., 2015).

Further, DMT increased accumulation of 3HDA and 3H3MT newly formed from 3HDOPA (Waldmeier and Meitre, 1977). 3,4-Dihydroxyphenylacetic acid (DOPAC, a major metabolite of dopamine) more efficiently lowered by DMT rather than HVA (Waldmeier and Meitre, 1977) in the striatum and whole brain. This is distinct from the effects of classic MAOIs, which decrease both DOPAC and HVA (Maitre et al., 1976; Waldmeier et al., 8 best opioid detox and rehab centers 1976). After acute administration striatal dopamine synthesis was increased, yet there was no effect on steady state conditions. Dopamine degradation must be enhanced proportionally and is likely done so extraneuronally, due to the increase in 3-MT (Rech et al., 1971; Smith, 1977). No change in the increase of DA turnover over one month treatment (5 mg/kg, Smith, 1977), with consistent rises in 3-MT is observed.

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. The putative roles of DMT will be explored in more detail in subsequent sections of this review. The review will begin by addressing the basic mechanisms of action of DMT, both pharmacokinetic and pharmacodynamic.
