Brief overview - What is DMT?

NN-Dimethyltryptamine or DMT for short is an short acting psychedelic entheogen which allows a persons consciousness to voyage into the most incredible dimensions, visions, thoughts and experiences imaginable.

It is one of the most powerful yet mysterious psychedelics in existence, but in the opinion of many users, to classify DMT as merely a drug would be doing it a great injustice as DMT seems to some as a trans dimensional key into places and vistas so profound and awe inspiring that it raises many new questions regarding the nature of reality and our place within it. Nevertheless, it is important to realize that the experience may be very difficult for some to integrate, and a great care and respect is necessary to use it. Please check Health and Safety section for more info.

DMT exists naturally in every human being and also throughout the plant and animal kingdoms. It occurs naturally in many mammals, marine animals, trees, grasses, flowers and shoots.

DMT is closely related to serotonin, the naturally occurring neurotransmitter that psychedelics affect so widely. The pharmacology of DMT is similar to that of other well-known psychedelics. It affects receptor sites for serotonin in much the same way that LSD, psilocybin, and mescaline do. These serotonin receptors are widespread throughout the body and can be found in blood vessels, muscle, glands, and skin.

There are a number of ways to acquire this entheogen. The first and most difficult way is to have some substantial chemistry knowledge and experience and actually synthesize pure DMT in a laboratory. This a rather tricky and time consuming process and requires access to some rather obscure and hard to acquire chemicals.

The most common and easiest method to acquire DMT is to extract it from the various plant species that contain the compound. The various plants and extraction techniques can be found further down this page.

Subjective effects

Depending on the dosage and form of ingestion, the effects of DMT can range from a multitude of sensations, from light, subtle perceptual changes, to bizarre, beautiful and even 'impossible' visions , and to literally jaw hanging awe as one is propelled into other dimensions of existence where human language and logic cannot even begin to describe or comprehend.

There have been a few attempts to define different levels and types of experience. Psychedelic Monographs and Essays Psychedelic Monographs and Essays discusses different levels of a DMT experience.

The Hyperspace lexicon project is an attempt to create a new vocabulary to try to describe the DMT realm.

Another way to get a small glimpse of the effects it can generate from a subjective point of view, read the areas of the forum dedicated to experience reports (1, 2)

Physical effects

Increase in heart rate and blood pressure. Severe mydriasis. Very even breathing. Trance like effects.

Combinations / Synergies / Interactions

Below are some of the effects of interaction between DMT and other substances:

  • With harmine/Harmaline: Harmalas activate DMT orally by temporarily inhibiting MAO-A. Harmalas (sublingual, oral or vaporized) also extend the duration of a vaporized DMT experience, and can help some remember better the experiences with the slower comedown, but specially in higher doses harmalas might make the experience heavy/foggy and not allow for a clean breakthrough. Some people enjoy it, others prefer vaporizing without harmalas. The ones that do like it, usually prefer in smaller/medium doses of harmalas instead of higher doses.
  • DMT & Harmala: Dosage and Routes of Administration (smoking, oral, sublingual, snorting...)
  • With cannabis: DMT vapor is cool. Cannabis smoke/vapor is hot. This can make for difficult hits as well as difficult to hold hits when using DMT in a cannabis changa or with some cannabis herb. When used before launch cannabis can help or hinder the process of dealing with anxiety. Also, when used before launch, many report damped down visuals. Finally, with this combo, memory of the trip can be even more difficult. Cannabis is very pleasant during the comedown from DMT.
  • With mushrooms: DMT vaporized during the mushroom experiences are very intense, and the preferred combination of some. Trout reports some to find it disorienting.
 (Pandora) Very intense has included heavy audio hallucination along with open eyed full on breakthrough visuals of an "attack" nature as well as cognitive delusion for me.
  • With LSD: Many people really like the experience and find it can be really beautiful and ecstatic. Others find in spite of beautiful visuals, the LSD acts as an anchor and prevents breakthrough.
 (Pandora) - One of the most intense and profound combinations.  Takes me a higher dose than usual of DMT to breakthrough - benzyme says due to competition at receptor site.  The visuals are an order of magnitude or three greater than DMT alone and open eyed can turn the world into a vibrating, synergistic, Legoland.  During the comeup it eases me through the transitions and plunges me right into heavy LSD tripping (when DMT fades).  During peak it is almost guaranteed ego death/mystical.  During comedown, ratchets my LSD trip back up (when DMT fades) and frankly is very erotic.
  • With mescaline: As with LSD
  (Pandora) - Mescaline and DMT yield more organic and less Lego-like visuals for me with generally darker colors than the LSDMT combo.  I find that the Mescaline DMT combo radically extends the peak DMT effects for me.
  • With Chlorpromazine: Diminishes effects (Trout's Notes)
  • Benzodiazepines: The psychedelic community generally considers that aborting a bad trip with such substances is counterproductive and can generate long lasting psychological issues. Gentle comforting approach is generally recommended and thought to be of great effectiveness. Being reassuring and calm, maybe a warm blanket or a tea or a juice, can go much farther and deeper in resolving a psychedelic crisis situation, as it has been shown in several real-world observations. In any case Trout reports 0.5-1mg of Alprazolam can smooth an agitatedly rough or unpleasant trip or perception of body load, or enabling of sleep at the end of an intense session involving stimulant psychedelics or "party" drug combinations. (Trout's Notes)
  • With MDMA: Mixed responses. Check this thread for some more info. Do NOT mix changa containing MAOIs with MDMA, and certainly neither oral MAOIs and MDMA.
  • With LSD+MDMA (candy flip): Launching is much more comfortable than with LSD alone, though effects are mixed as with DMT and MDMA alone and Pandora has purged on this combo twice.
  • With 2CB: Intensely insightful with lasting impact. See yourself and your memories in a new light.
  • With 5-meo-MIPT: Pandora found this similar to the LSD combo without the ultimate ego-death/mystical peak.
  • With Ketamine: Friendly, thickly visual and seductive combination. Ketamine makes for a completely relaxed, warm, anxiety-free launch. Pandora prefers a non-dissociative dose of K (under 50 mgs) and a number of changa hits over one hour for the ideal DMT/K session. Memories are elusive here.
  • With MXE: Same as with Ketamine but more so. Pandora finds DMT to be best on the comedown but needs more assays. Warm, comfy, extended stays in hyperspace with things moving slowly or not at all. A sense of floating and moving in curves in a zero-G environment. Strong feeling of "instant integration" when the trance breaks.

Pharmacology, toxicity and general safety


DMT is inactive when taken orally, unless if ingested together with MAOI.

After intramuscular injection it is rapidly metabolised primarily into indol-3-ylacetic acid. About 33% of the dose is excreted in urine in 6 hours as free and conjugated (glucoronide) indol-3-ylacetic acid. Less than 0.1% of the dose is excreted unchanged in the urine in 24 hours (Clarke's second, 1986)

DMT is an agonist of serotonin 5-HT2a, 5-HT2c and 5-HT1a

Plants containing DMT

The following is a list of plants known to contain DMT. Plants no containing other tryptamines can be found in the page of each tryptamine, such as 5-MeO-DMT, Bufotenine, or other Alkaloids.

In some of the plants in the following list, the DMT content may be very small or it may be present together with other potentially unwanted alkaloids. Please research well before extracting from some plant, and be sure you have your desired alkaloids only when bioassaying from a new plant. For more information,

Mimosa verrucosa

  • This is included by a number of authorities. I can locate no published analysis on any material under this name.

  • Mimosa verrocosa is said by Da Mota 1991 to be used in making jurema, but to have sedative and not hallucinogenic effects. (Trout's Notes)
  • Silveira Barbosa 1998 found it in use as a probable DMT containing brew in Brazil but (unlike M. hostilis] it appeared to be orally active as a hallucinogen only when an MAOI was coadministered. Her report of full activity with MAOI supports DMT's presence. (Trout's Notes)

Humans and other animals

Paramuricea cluunaeleon

Coral, less than 5mg per 200g, Cimino & DeStefano 1978


Saavedra & Axelrod 1972 showed that MMT and DMT can be formed in rat brain and that an enzyme is present that is capable of performing this reaction. They also found that something else is present which inhibits this reaction.

Humans (ref Trout's Notes)

  • Plasma concentrations of endogenous dimethyltryptamine are generally <0.001 mg/L. Fifteen male volunteers, between the ages of 26 and 48 years, were administered 2 mL/kg of hoasca tea, an Amazonian sacramental beverage. The tea alkaloid content was determined to be as follows: DMT 0.24 mg/mL, harmine 1.70 mg/mL, harmaline 0.20 mg/mL and tetrahydroharmine 1.07 mg/mL. The mean peak plasma concentration of dimethyltryptamine was 15.8 mg/L, reached after 107.5 min, which coincided with peak times of psychoactivity [Callaway et al. 1999].
  • After IM injection of 0.7 mg/kg to 11 subjects, peak blood concentrations averaged 0.1 mg/L at 0.17 h, coinciding with the maximum psychoactive

effects [Kaplan et al. 1974].

  • See the review of biogenic amines reported in human body fluids by Bruce Davis 1989.
  • Clarke's Second Edition notes that natural endogenous concentrations in plasma are normally less than 0.001 ug/ml and that IM administration of 0.7 mg/kg resulted in an average concentration of 0.1 ug/ml at 0.17 hour. Said to be the time of maximum effect via this route. This is fascinating as it implies that strongly entheogenic activity is a result of elevation of the concentration by less than 100 times that of the naturally occurring baseline.
  • DMT was found in normal human blood and urine by Franzen & Gross 1965.
  • Sample analysis of human cerebrospinal fluid included DMT. Christian et al 1975.
  • Found in cerebrospinal fluid of psychotics and normal people. Corbett et al 1978.
  • Narasimhachari et al. 1971a found DMT in schizophrenics but not in normals.
  • Narasimhacbari et al 1971b reported it in most psychotics but only 2 out of 20 normals.
  • Smythies et al 1979 found it at wildly varying levels in both populations.
  • Lipinski et al 1974 found it in some psychotics.
  • Oon & Rodnight. 1977 thought they observed DMT in psychotics but did not positively prove. See also Oon et al. 1977 and his references.
  • For additional references on the natural and potential occurrence of DMT in mammals and humans see:

Beaton & Morris 1984 Christian et at. 1976 & 1977 Raisanen & Karkkainen 1979 (in urine) Rosengarten & Friedhoff 1976 Saavedra & Axelrod 1972 Tanimukai et al 1970 Wyatt et al 1973 (found at variable levels in plasma of both psychotics & normals.) For references on occurrence in normal populations versus psychotics, see articles just mentioned , also those by Barker or Christian above, and Davis 1989 - Davis noted that those studies failing to find DMT were the ones that relied on less sensitive assay methods. Oon et al 1977 See discussion & references in Gillin et al 1976.

Dosages and consumption methods

Ingestion Methods WIKI

Smoked / Vaporized

Extracted DMT freebase can be vaporized for very potent effects that last around 10 minutes. DMT is ideally vaporized, as opposed to smoked. Vaporization is achieved by a controlled temperature that does not burn/combust DMT material (and potential impurities), but instead just makes DMT evaporate and be inhaled.

Vaporization is much smoother than smoking. Smoking leads to break down of DMT (and impurity) molecules into potential toxic nitrogen oxides (Trout's notes), so not only it is harsher but also there is a significant loss of actives.

Vaporizing can be achieved with improvised vaporizers such as The Inspirator mkII, or commercially sold vaporizing pipes such as the VaporGenie and oil/dab rigs [2].

Some methods, such as The Machine, if it's very carefully done, keeping the lighter farther away, one can also vaporize DMT, but due to lack of adequate buffer between the fire and the alkaloids, often will also generate combustion.

The GVG (Glass Vapor Genie) is usually touted as the most efficient/effective method of vaporizing DMT, however, recent exploration into dabbing DMT has proved to be at least as efficient and effective for many users. One advantage of dabbing DMT is that all of the vapor can be cleared in a single hit and is much smoother/less harsh than with the GVG. This is likely due to water cooling and increased distance of vapor travel. When dabbing DMT, however, one must ensure that the nail is sufficiently hot so that the Leidenfrost Effect can occur, resulting in the DMT being vaporized above the surface of the nail.[3]

Smoking is nonetheless still a popular way of ingesting DMT, and is often done by infusing herbs with the DMT, or smoking in a bong, with the DMT sandwhiched between thick layer of ashes or thin layer of herbs that serve to protect the DMT from fire (though there is still combustion, specially when using herbs).

Dosages are around 20-30mg for efficient vaporization methods, and with smoking methods can be around 50-60mg or even more....


DMT is only active orally when taking together with a MAOI. (FAQ for more info)

Dosages for DMT, considering MAOs are fully inhibited, vary wildly depending on person, probably due to metabolism in great part. They can go from 30 to 250mg! If its your first time, start on the lower end!

Another factor is whether one is ingesting a whole plant brew or purified extracts. Often in ayahuasca analysis the amount of DMT found is very small (20-30mg), but also often there is redosing in ayahuasca sessions, but also its possible other trace amount of beta-carbolines and alkaloids can improve MAO inhibition, or that other inactive plant substances can help protecting DMT from fast breakdown by any potential active MAO.

There are a few different ways to ingest it orally:

- Dissolved in acidic juice - Rolled inside a bit of smoking paper and swallowed like a pill - Put into 00 Capsules


This is a method that gets very opposite responses from different people. For many, it hurts too much and isn't effective. For others it works well and pain/discomfort is tolerable, and the effects are worth it. It is unknown what possible health consequences snorting a basic alkaloid such as DMT can have on nasal passages, specially long term use, so we advice caution. There are some attempts to find less harsh ways, check threads below for more info:
