The Ultimate Guide to DMT



Disclaimer: DMT is a potentially illegal substance, and we do not encourage or condone the use of this substance where it is against the law. However, we accept that illegal drug use occurs, and believe that offering responsible harm reduction information is imperative to keeping people safe. For that reason, this guide is designed to ensure the safety of those who decide to use the substance.



DMT, or N,N-Dimethyltryptamine, is a naturally occurring chemical found in both plants and animals. It is the active hallucinogenic compound in ayahuasca, the Quechua name for a tea brewed from the shrub Psychotria viridis, which is used for ritual purposes by the indigenous people in the Amazon. See our ayahuasca guide for more on this psychedelic brew.

Dimethyltryptamine can also be ingested in crystal form, where it is often smoked in a pipe or bong, as well as vaporized. Taken in this manner, it produces a powerful but short-lasting hallucinogenic state that is considered one of the most intense psychedelic experiences in existence.

It can also retain its psychoactive properties in other forms, including psilocybin (4-PO-HO-DMT, found in psilocybin mushrooms).



Physiological effects

The psychedelic threshold for DMT is about 0.2 mg/kg. When smoked, it’s a very fast-acting substance with peak subjective experience occurring around 2 minutes after ingestion, and completely resolving within 15 to 20 minutes.[5] When taken as an ayahuasca brew, the effects can take up to an hour to appear, and may last for several hours.

A study in the 1990s examined the dose effects of intravenous DMT at 0.05, 0.1, 0.2 and 0.4 mg/kg in a double-blind, randomized design, using 12 volunteers.[6] The Hallucinogen Rating Scale (HRS), that was developed and used for this study, grouped responses into six clinical categories: Affect, Volition, Somatic Effects (‘Somaesthesia’), Perception, Cognition, and Intensity.

The ‘psychedelic’ threshold for DMT was at 0.2 mg/kg, at which most biological effects were also detectably altered. Adrenocorticotropin hormone, beta-endorphin, prolactin, growth hormone (GH) and cortisol were all elevated following DMT administration. Pupil diameter, heart rate, blood pressure and all peaked within 2 min as did subjective experiences.

No evidence of tolerance (needing to take more for the same effect) for DMT was found in a later trial.[7][8]

Psychological effects

Low doses (0.05 to 0.1 mg/kg) of dimethyltryptamine primarily affect physical and emotional states with few to no perceptual hallucinations. Higher doses typically produce a rapidly moving kaleidoscopic displays of intensely “techno-colored” abstract and representational images. Auditory hallucinations are less common and usually aren’t a very prominent feature of the experience. Alternating sensations of heat and cold are sometimes reported.

Transient states of anxiety are quite common, though so are euphoric states and, somewhat paradoxically, they can be experienced simultaneously. Out-of-body experiences, or a dissociation of awareness from the physical body, is very common with DMT (at higher doses) to the point that many consider it a hallmark of the experience.

In his 2000 book, The Spirit Molecule, Rick Strassman describes studies in which about half of the volunteers during a DMT trip entered “freestanding, independent levels of existence” — psychological planes of existence that were often inhabited by “intelligent beings”, “entities”, “aliens”, “guides” and “helpers”. Terrence McKenna called these “machine elves”. According to Strassman’s work, they take the form of “clowns, reptiles, mantises, bees, spiders, cacti and stick figures.” Reports of these kinds of beings seem to be unique to DMT trips.

Risks & Side Effects


Seeing as DMT is found endogenously in the human brain, our bodies are quite used to handling this molecule. Research has also suggested that it has an important role in various processes taking place in the central and peripheral nervous systems. The reason why DMT trips (without MAOIs taken beforehand) are so short-lived is actually because we are so good at metabolizing it. All this said, DMT is quite a safe compound to ingest, one that our systems are intimately familiar with.

However, it is still a highly potent psychedelic that does cause a range of changes in the functioning of our minds and bodies, especially at high dosages. Among these changes, there are some things to watch out for:

  • First, the most common physiological side-effects include: elevated blood pressure and heart rate, dizziness, lack of coordination, nausea (if DMT is taken as part of ayahuasca), shivering, and potential loss of consciousness. This means that anyone with a heart condition should take high precautions if smoking DMT. Other risks involved here concern the logistics of ingestion: DMT is best enjoyed in a comfortable environment where there is little risk of injury. Walking is not an endeavor to be attempted while tripping, and the setting should have plenty of space in case it is.
  • As for the psychological effects: DMT can cause intense open-eyed hallucinations, which can completely alter perception of the environment. This can result in heavy confusion, which may escalate into anxiety or panic. The closed-eyed visualizations can also be quite wild and overwhelming, and may cause a feeling of discomfort or fear or, more extremely, psychological trauma. In some users, DMT induces a feeling of separation between the mind/soul and the body. Losing this connection can catalyze an incredibly powerful and profound shift in consciousness, but it can also produce symptoms of depersonalization.
  • Lastly, the cases where it really might be potentially harmful is when there is interaction with other drugs or substances. Refer to the Pharmacology section of this guide for more information.

In order to ensure your safety, when taking DMT, you are advised to always have a sober sitter present. We can’t stress the importance of this enough.

How to Get DMT


There are many ways to extract freebase dimethyltryptamine from plants that contain it. The chemistry behind it is reasonably simple, but the extraction process itself should be approached with caution and carried out with preciseness in order to get good quality results.

The simplest method to extract DMT involves dissolving the ground up plant matter in a base solution – most commonly sodium hydroxide (NaOH). The molecules of DMT are then released and need to be separated from the remainder. This is done with a non-polar solvent such as naphtha (or with a pure alkane). These chemicals will attract the non-polar DMT molecules and float it up to the top, forming a separate layer. All that’s left then is to syphon the DMT-containing solution out, freeze it, filter it through a coffee filter and dry it out in order to get the pure crystal.

An additional step can be taken to further refine the DMT. This is called recrystallization, and it involves creating a solution of the powder yielded from extraction and the non-polar solvent. When DMT is dissolved, it should be frozen and then filtered and dried again. This can be repeated for even greater refinement.

There are more complex ways to extract freebase DMT, and, generally speaking, the more work they take, the better and more pure the yield will be. You can find many methods described in great detail here. We recommend Noman’s tek as the best in terms of complexity to yield ratio.

Personal Growth


Anecdotal reports suggest that greater self-awareness and spiritual connection to the world can be gained from properly using DMT. Just as ayahuasca ceremonies can provide new perspective on inner emotional realities to people with mental and addictive disorders, DMT can be used to achieve new perspective in one’s spiritual life.

Many report that DMT gives them a connection to unconscious parts of their mind, allowing them to see any issues and mental blocks they’ve been experiencing from a new vantage point. People often report a sense of detachment from their emotions and how they identify with them as well.

When it occurs, the dissolution of ego and “self”, while jarring, is often reported to be one of the most powerful personal insights people experience during a DMT trip. The idea that ‘you’ are not who you think you are is difficult to grasp for many, especially in Western society where the individual is held up as the paragon of modern civilization. A trip that includes a dissolution of one’s identity, sometimes dubbed “ego death”, forces this radical new perspective on to the user.

Major shifts in perspective like the ones enumerated above are often reported as the initial catalysts for subsequent spiritual and personal growth; although a guide or sitter is always recommended due to the potentially traumatic nature of an intense psychedelic experience.

Anecdotal reports of the personal development effects of ayahuasca:

Psychedelic retreats

DMT is a powerful tool by which interconnectedness and sense of belonging to something greater than oneself can be realized and integrated into your everyday life.

As such, psychedelic retreats such as Synthesis (in Amsterdam) and Rythmia (in Costa Rica) have become popular, as people search for ideal ways to translate the psychedelic experience into lessons for living a better life.

Retreats can be varied in their focus and approach. Larger, more expensive retreats like Rythmia use the formidable psychedelic brew ayahuasca to induce intense spiritual experiences in guided ceremonies, over the course of several days. Smaller, less intimidating retreats like Synthesis offer psilocybin truffle experiences personalized to the individual participants, designed to help you get what you want out of the retreat.

If you decide you are interested in taking part in a psychedelic retreat, research your options to make sure you are signing up for the right experience.

Therapeutic Use


While the therapeutic value of DMT alone has not been explored to the extent that other psychedelic drugs have, the DMT-containing brew ayahuasca has long been used traditionally to treat various psychological maladies, including mood disorders and addiction. Ayahuasca has seen an increase in use in the modern world as a potential treatment of depression and addiction.

A review of six studies between 1990 and 2015 found that ayahuasca (along with LSD and psilocybin) holds promising potential for treating depression, anxiety, and tobacco addiction, and alcoholism.[12]

Researchers have proposed that ayahuasca’s therapeutic effects come from its ability to induce greater mindfulness in users.[13] Following an ayahuasca experience, decreases in self-judgment and emotional reactivity to inner experiences help foster a sense of self-acceptance, widely agreed to be a critical step in healing mood and addictive disorders.

Anecdotal reports of the therapeutic effects of ayahuasca:



DMT is internationally controlled according to the UN’s Convention on Psychotropic Substances.[14] DMT-containing plants may not be technically illegal where DMT is but obviously the extracted alkaloid is.

Note: The legality of ayahuasca is covered separately in the ayahuasca guide.

Where is DMT legal?

The following information may not always reflect the latest developments, but we’ll endeavor to keep it up to date. It is only intended to cover the personal, non-medical possession and use of DMT.

Countries where DMT is legal

DMT doesn’t appear to be legal in any country at present.

Countries where DMT is decriminalized

There appears to be no risk of a criminal penalty for the personal (i.e. “small” quantity) possession or use of DMT in:

  • United States: Oakland, CA (in plants)[18][19]; Santa Cruz, CA (in plants)[20]

Important: Decriminalization isn’t a free pass to use DMT however you want. The specifics depend on the country or region and, crucially, on the amount you have in your possession. Confiscation is common, but there may be other, more severe non-criminal outcomes such as fines, driving license suspension, and deportation.

Countries where DMT is illegal

Although DMT is illegal or controlled in each of these countries, there may be regional or circumstantial (e.g. religious) exceptions, as noted below:



Dimethyltryptamine is primarily a serotonin (5-HT) receptor agonist and, like many others in its class, its psychedelic actions can mostly be attributed to its effects on the 5-HT2A receptor subtype. It does affect many other receptor types (for example, dopamine and sigma receptors), but the consequences of these interactions are not well understood.[3]


The exact toxic profile of DMT is unknown, but studies in rodents suggest that a lethal dose in humans would be extremely high; more than 20 times the typical dose given during an ayahuasca ceremony.

A group of experienced users were asked to rate its safety, with 55% reporting it to be “very safe” and 38% “quite safe”.[4] The main risks they reported were a “bad trip” (51%), which is considerably higher than the risk of bad experiences with the other classic psychedelics, LSD and psilocybin.


DMT significantly affects the serotonin system and should not be taken simultaneously with any of the following substances

  • SSRI’s (any selective serotonin reuptake inhibitor, like Prozac)
  • antihypertensives (high blood pressure medicine)
  • appetite suppressants (diet pills)
  • medicine for asthma, bronchitis, or other breathing problems; antihistamines, medicines for colds, sinus problems, hay fever, or allergies (any drug containing dextromethorphan/ DXM or with DM, DX or Tuss in its name)
  • CNS (central nervous system) depressants (xanax, ativan, etc)
  • Vasodilators
  • Antipsychotics
  • Barbiturates
  • Alcohol

Illegal or recreational drugs that are VERY dangerous to combine with MAOIs:

  • Cocaine
  • amphetamines (meth-, dex-, amphetamine), ephedrine, MDMA (Ecstasy), MDA, MDEA, PMA
  • opiates (heroin, morphine, codeine, and especially opium)
  • dextromethorphan (DXM)
  • Nutmeg

Illegal or recreational drugs that can be dangerous to combine with MAOIs:

  • mescaline (any phenethylamine)
  • barbiturates
  • alcohol
  • kratom
  • kava
  • 5-MEO-DMT

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

For years, there has been a raging debate about whether or not DMT is a “naturally occurring” compound. It had been found in a number of plants and animals and in 1965, German researchers were able to isolate it in human blood and urine,[9] though the credibility of these results have been criticized. Subsequent studies, however, have detected naturally-occurring DMT in human blood, urine, feces, kidney tissue, lung tissue, and spinal fluid. In 2014, a study found that DMT aides the immune response in some cells by through simga-1 receptors and may play a role in tissue regeneration.[10]

The true debate, however, is whether or not DMT is produced in the brain. Some new evidence suggests that it might be. In 2013, scientists isolated DMT from the rat pineal gland, proving that the mammalian brain is at least capable of producing the substance.[11] Whether or not DMT is actually produced in the human brain remains to be verified.

Rick Strassman is sometimes “blamed” for throwing false fuel on the fire of this debate in his book, The Spirit Molecule, but he really isn’t at fault. As he later put it:

“I did my best in the DMT book to differentiate between what is known, and what I was conjecturing about (based upon what is known), regarding certain aspects of DMT dynamics. However, it’s amazing how ineffective my efforts seem to have been. So many people write me, or write elsewhere, about DMT, and the pineal, assuming that the things I conjecture about are true. When I was writing the book, I thought I was clear enough, and repeating myself would have gotten tedious.

“We don’t know whether DMT is made in the pineal. I muster a lot of circumstantial evidence supporting a reason to look long and hard at the pineal, but we do not yet know. There are data suggesting urinary DMT rises in psychotic patients when their psychosis is worse. However, we don’t know whether DMT rises during dreams, meditation, near-death, death, birth or any other endogenous altered state.”

History & Stats


Information from Winstock et al, 2013 [1]

Traditional use of DMT dates back as far as the late 8th century, when it was used as an ingredient in various psychoactive snuffs. It occurs naturally in various plants, including the seeds of A. peregrina, which were the main ingredient of cohoba snuff. As well as various forms of psychoactive snuff, other traditional preparations are made using DMT-containing plants, including the vilca and ayahuasca brews.

Richard Helmuth Fredrick Manske is credited as the first to synthesize dimethyltryptamine in 1931. But it was Dr. Stephen Szara, who, inspired by visiting South American religious ceremonies, first demonstrated in 1956 that the drug induces hallucinations, illusions, distortions of spatial perception and body image, disturbances of thoughts, and euphoria in humans.

The first wave of clinical research followed in the 1950s and 1960s, gaining momentum with the discovery by Franzen and Gross in 1965 that DMT can be found in the blood and urine of normal human subjects. Following the passage of the Controlled Substances Act 1970, research into psychedelics waned in both the United States and Europe for many years.

Rick Strassman pioneered contemporary research into psychedelcis in the 1990s as he believed that the profound effects on consciousness they produced warranted further exploration. He published a number of landmark studies including detailed dose-response experiments using the Hallucinogen Rating Scale to measure subjective experiences. Strassman later published The Spirit Molecule in 2000, widely considered a landmark book on the many uses of DMT.

This new interest continued with the publication of Tihkal, by Alexander and Ann Shulgin. It was their personal study into the psychopharmacological properties of the tryptamines, including DMT, which described the subjective effects of smoked and oral preparations.

The Global Drug Survey in late 2012, with over 22,000 respondents, found a lifetime DMT use rate of about 9%. The most common route of administration reported in the survey was smoking as an herbal mixture (92%), as opposed to taking it orally as an ayahuasca preparation, for example.

An Australian study conducted in 2010 surveyed 121 people who had previously experienced DMT.[2]They found that smoking was by far the most common route of administration (98.3%) with a much smaller proportion reporting use of ayahuasca (30.6%). The reasons for first trying this tryptamine were out of a general interest in hallucinogens (46.6%) or curiosity about its effects (41.7%), while almost one-third (31.1%) cited possible psychotherapeutic benefits of the drug. An increase in psychospiritual insight was the most commonly reported positive effect of both smoked DMT (75.5%) and ayahuasca (46.7%).



Can DMT be detected in a drug test?

DMT is not included in a typical drug screen, nor is it included in any known extensive drug screens. It is also not chemically similar to substances that are typically tested for, so the likelihood of triggering a false positive for other drugs is near zero.

Can I test my DMT to see if it’s safe to take?

Testing your DMT is always good practice even when you trust your supplier. Reagent test kits from Bunk Police can identify hundreds of adulterants and substitutes—offering peace of mind and potentially saving your life.

The Hofmann and Mecke reagents, for example, can help identify real DMT. Simply place a tiny amount of DMT into a sterile test tube or onto a sterile white ceramic surface and add a few drops of the reagent. Then check the color change (or lack thereof) against the supplied spectrum booklet.

How do you take DMT?

DMT can be taken in many forms, but most typically it is either taken in the ayahuasca brew, or smoked as a powder. You can read a detailed guide to smoking it here. The powder form will produce a short-lasting but intense trip, and the ayahuasca brew will produce a long-lasting experience.

Is DMT safe?

On its own, DMT is quite safe to ingest in reasonable dosages. Any potential risks come from interaction with other substances, or taking it in an unsuitable setting.

Can I microdose with DMT?

There is not much information about DMT microdosing, as microdosing is most commonly performed with LSD and psilocybin. However, as DMT is a classic psychedelic in the same family as LSD and psilocybin, it can be microdosed in a similar way. Click here for a detailed guide on microdosing DMT.

Can DMT give me a bad trip?

Like most psychedelics, DMT is a very powerful drug, and has the potential to be very unpleasant if not treated with respect. Follow the 6S’s of psychedelic use to minimise the risks of a bad experience. Start with a low dose if it’s your first time.

Will I always achieve a breakthrough?

Not necessarily, especially if taken as an ayahuasca brew. However, DMT is a powerful psychedelic; when smoked, it is likely to produce out of body experiences and extreme changes in perception.

Is DMT produced naturally in the body?

This is an area of some controversy, but there is evidence to suggest that DMT is present in animal physiology. See here for more info.

Can I mix DMT with other drugs?

DMT should not be mixed with Tramadol, as it can lead to serotonin syndrome. Be cautious if mixing with cannabis, amphetamines or cocaine. Click here for a detailed chart of safe drug combinations.

Can I become tolerant to DMT?

DMT tolerance is considerably less than the other classic psychedelics. Wait an hour or two between doses for tolerance to return to normal. Similarly, ayahuasca does not produce tolerance.
