DMT attracts myths the way few molecules do. Some began as honest hypotheses that were never tested; some are real findings in rats retold as facts about people; some simply grew in the retelling. This article takes fifteen of the most repeated claims, gives each a verdict and a source, and explains the reasoning. For the basics, start with our pillar, what is DMT.

The 15 DMT myths at a glance

Myths about DMT in the brain and body

1. “The pineal gland floods the brain with DMT when you die”

Verdict: unsupported. The only measurement of DMT rising around death comes from rats. In 2019, DMT in the visual cortex of rats rose after experimentally induced cardiac arrest, and it did so whether or not the pineal gland had been removed (Dean et al., 2019). That moves the source away from the pineal, not towards it. Evidence: preliminary.

A 2018 review concluded that the pineal-release idea is not consistent with the evidence: the gland is tiny, its main job is making melatonin, and the minute amounts of DMT detected in brain are not enough to produce psychoactive effects (Nichols, 2018). No one has measured DMT in a living human brain at death or at any other time (Barker, 2018). Evidence: unresolved in humans. More in does the brain release DMT when you die.

2. “The pineal gland releases DMT at birth and in dreams”

Verdict: unsupported. Nichols lists secretion of DMT by the pineal at birth and during dreaming among the ideas the evidence does not support (Nichols, 2018). Part of the story traces to Rick Strassman’s 2000 book, whose preface lists among its “highly speculative” proposals that pineal DMT release 49 days after conception marks the entrance of the spirit into the fetus (Strassman, book page). In his own 1994 study, DMT left melatonin, the pineal hormone, unaffected (Strassman and Qualls, 1994). Evidence: unresolved, with no human data either way. See why DMT is called the spirit molecule and DMT and dreams.

3. “The human brain makes as much DMT as serotonin”

Verdict: misleading. The comparison is real but comes from rats: extracellular DMT in rat cortex was “similar to those of canonical monoamine neurotransmitters including serotonin” (Dean et al., 2019). The same authors only “raise the possibility” that this happens in humans. Evidence: preliminary.

In people, DMT has been detected in blood, urine and spinal fluid, but there have been no efforts to measure it in the human brain (Barker, 2018), and a 2022 review notes that only a handful of studies have tried to detect DMT in the human brain at all, and only indirectly, through cerebrospinal fluid (Barker, 2022). Evidence: unresolved in humans. See does the brain make DMT and the rat brain study explained.

4. “Scientists know which enzyme makes DMT”

Verdict: unresolved. Textbooks credit an enzyme called INMT. But rats bred without INMT still showed tryptamine-methylating activity in brain and lung, and the products were not the expected ones (Glynos et al., 2023), and mice without INMT showed no obvious drop in their own psychedelic tryptamine levels (Hatzipantelis et al., 2025). Both teams suggest another pathway may exist in rodents. Evidence: unresolved. See INMT, the enzyme linked to DMT.

5. “Your brain releases DMT for seven minutes after death”

Verdict: unsupported. We found no study that measured a seven-minute window of DMT release in dying people, and we could not trace the figure to any research.

The real findings it may be built on are about electrical activity, not DMT. In rats, a surge of synchronised gamma waves appeared within the first 30 seconds after cardiac arrest (Borjigin et al., 2013); in four dying patients whose ventilation was withdrawn, two showed a similar gamma surge (Xu et al., 2023). Neither study, as described in its abstract, measured DMT, and nobody can know from brain waves alone what, if anything, was experienced. Evidence: preliminary for the gamma surges; the seven-minute DMT claim has no source we could find.

Myths about the DMT experience

6. “Everyone meets machine elves”

Verdict: false. The largest analysis of written reports coded 3,778 experiences posted to an online forum over ten years. Machine elves made up 2.9% of entity encounters, within a broader “mythological beings” group of 8.4% (Lawrence et al., 2022). Feminine beings (24.2%), deities (17.0%) and aliens (16.3%) were all far more common. The authors were coding self-selected posts, so the true mix in any population is unknown. Evidence: preliminary. See what machine elves means.

7. “Everyone, or about half of people, meets entities”

Verdict: misleading. The answer depends on who is asked and how. In the forum analysis, 45.5% of experiences described an entity (Lawrence et al., 2022); in a lab interview study, presences featured in 17 of 23 interviews (Sanders et al., 2026); in a home field study of experienced users, 94% (Michael et al., 2021); and in a survey of 2,561 people, 100%, because it recruited people who had had an encounter (Davis et al., 2020). There is no single rate. Evidence: preliminary. See DMT entity encounters: what the research says.

8. “It feels more real than reality, so it must be real”

Verdict: unsupported. A feeling of realness is a report about an experience, not a measurement of the world. In a 2019 survey, people who described drug-free “God encounters” rated them as more real than everyday consciousness at 72.7 out of 100, close to the 77.5 given for DMT encounters (Griffiths et al., 2019). And realness is not universal: in a 2026 lab study, 22% of participants described the experience as real and 9% as unreal (Sanders et al., 2026). Whether anything encountered exists outside the brain is unresolved; the feeling alone cannot settle it. See why DMT feels more real than reality.

9. “DMT explains near-death experiences”

Verdict: misleading. The two overlap. In a placebo-controlled study of 13 volunteers, DMT significantly raised scores on a near-death experience scale (Timmermann et al., 2018), and in a 2025 comparison, 95% of 36 DMT participants reported at least one classic near-death theme. But the same comparison found that five classic near-death features were entirely absent from DMT reports and that detailed content diverged (Michael et al., 2025). Similar is not the same as explained, and there is no human evidence that DMT is released at death (myth 1). Evidence: preliminary. See DMT and near-death experiences.

Myths about tolerance and the brain

10. “You can’t build tolerance to DMT”

Verdict: misleading. It rests on one real result. In a 1996 double-blind study, 13 experienced volunteers received four closely spaced doses (dose not reproduced here): tolerance to the subjective “psychedelic” effects did not occur, but hormone and heart-rate responses decreased with each repeat (Strassman et al., 1996). Newer studies giving DMT as a continuous infusion found that subjective effects reached a plateau after about 30 minutes (Vogt et al., 2023), and one reported “moderate acute tolerance” (Erne et al., 2025). Evidence: preliminary, from small studies of healthy volunteers. More in is DMT addictive.

11. “DMT grows new brain cells and binds the BDNF receptor”

Verdict: misleading. A 2018 study found that psychedelics, DMT among them, increased the growth of neuron branches and spines in cultured neurons and in rats (Ly et al., 2018). That is structural plasticity (neurons growing new connections) in animals and cells, not new brain cells in people. Evidence: preliminary.

The widely cited 2023 paper showing psychedelics binding TrkB, the receptor for the growth factor BDNF, tested LSD and psilocin, not DMT (Moliner et al., 2023). A separate claim, that DMT works through the sigma-1 receptor, rests on cell and mouse work (Fontanilla et al., 2009), and DMT acts there only at concentrations far above those it needs at 5-HT2A (Barker, 2018). Evidence: preliminary. See is DMT neuroprotective and DMT and the sigma-1 receptor.

Myths about “natural”

12. “DMT is in every plant”

Verdict: misleading. Reviews describe DMT as produced by “a wide variety of plant and animal species” (Cameron and Olson, 2018) and as “widely found in plants and animals” (Carbonaro and Gatch, 2016). Wide is not universal: neither review says every plant contains it, and we found no source that does. We deliberately do not list which plants contain it. Evidence: established that it is widespread; the “every plant” version has no source.

13. “DMT is natural, so it’s safe”

Verdict: false. Natural origin says nothing about risk. In a 1994 controlled study, DMT raised blood pressure, heart rate, pupil size and body temperature, rising with the dose (Strassman and Qualls, 1994). In a 2020 survey, 41% of respondents reported fear during their most memorable encounter (Davis et al., 2020). A 2016 review notes intense cardiovascular effects when given intravenously at high doses (Carbonaro and Gatch, 2016). Evidence: established.

Canada’s Centre for Addiction and Mental Health warns that most hallucinogens are illegal and unregulated, may contain toxins or not contain the drug they are sold as, and can leave people disoriented, with poor judgment and more likely to take risks (CAMH). Controlled studies screened and supervised their volunteers, so they do not describe risk outside a hospital. Evidence: established.

14. “DMT is natural, so it’s legal”

Verdict: false in Canada. N,N-dimethyltryptamine and any salt of it is item 7 of Schedule III of the Controlled Drugs and Substances Act, which prohibits possession except as authorized under the regulations and separately prohibits trafficking and production, with exemptions possible under section 56 (CDSA). We read the consolidation current to 30 September 2026. The schedule entry describes the molecule by structure and makes no exception for DMT that occurs in nature. Evidence: established. This is general information, not legal advice; see is DMT legal in Canada.

A myth about the history

15. “Strassman gave DMT to 400 people until the government shut him down”

Verdict: false on both counts, by Strassman’s own account. On his website he writes that over the five years of his University of New Mexico project he gave approximately 400 doses of DMT to 60 volunteers, not 400 people, and that “problems inside and outside of the research environment” led to the end of the studies in 1995 (Strassman, book page). He does not describe a government shutdown there. These are his own figures and his own explanation. Evidence: established for what he has published; the detailed causes are his account. See Rick Strassman’s DMT study.

Why do DMT myths spread?

• Rat findings get retold as human facts. The best brain data on DMT come from rats (myths 1, 3 and 5).
• Hypotheses outlive their caveats. Ideas offered as speculation in a 2000 book are now repeated as findings (myth 2).
• One study becomes a rule. A single 1996 tolerance result (Strassman et al., 1996) became “no tolerance” (myth 10).
• Vivid minorities become the norm. Machine elves are memorable, not typical (myth 6).
• “Natural” sounds reassuring. It says nothing about safety or law (Strassman and Qualls, 1994; CDSA) (myths 13 and 14).

What we still don’t know

• Whether the living human brain makes DMT in meaningful amounts, at death or at any time (unresolved).
• Which enzyme makes DMT in mammals (unresolved).
• How tolerance to DMT develops over longer or repeated exposure in people (unresolved).
• Why some people meet entities and others do not, and how expectation shapes it (unresolved).
• Whether any of DMT’s plasticity findings in cells and rats apply to people (unresolved).
