Other Names

Dimethyltryptamin, dimethyltryptamine, DMT,

nigerin, nigerina, nigerine (1946), AT,N-dimethyltryptamine,

3- [2-(dimethyl-amino)ethyl] -indole

Substance type: tryptamine (indole alkaloid)

R. H. F. Manske first created DMT as a synthetic

substance in the laboratory in 1931. It was not

until 1955 that it was isolated as a natural compound

in the seeds of Anadenanthera peregrina. It

is found in a great number of plants and also

occurs naturally in humans and other mammals

(see table, pages 853-854). N,N-DMT is closely

related to 5-MeO-DMT and psilocybin/psilocin.

N,N-DMT and 5-MeO-DMT are among the

psychedelics whose effects are short in duration.

They are not orallyRoute of administration in which the subject swallows a substance. effective in an isolated form (as

a salt or abase) because the MAOMonoamine Oxidase, an enzyme that catalyses the metabolism of many drugs (e.g., DMT, dopamine and serotonin). enzyme breaks

them down before they can pass through the

blood-brain barrier (cf. ayahuasca, f3-carbolines).

They reveal their awesome effects only when

injected by syringe (Strassman et al. 1994),

snuffed, or smoked. When N,N-DMT or 5-MeODMT

is injected intravenously, the effects last

some forty-five minutes; when the substance is

smoked or snuffed, the effects last only ten

minutes. Subjectively, however, those few minutes

may seem to have spanned centuries. People who

have had experiences with DMT unanimously

agree that it is easily the most powerful psychedelic

known (cf. McKenna 1992; Meyer 1992).

Some people have described DMT as "crystallized

consciousness." When DMT is smoked, it is said

that the "scent of enlightenment" fills the air. Only

"a few seconds after taking it, DMT acts like the

trumpets of Jericho upon the gates of perception"

(Kraemer 1995, 98). DMT experiences can be so

extraordinarily alien that most subjects find it

extremely difficult or even impossible to describe

them in words. Many people speak of contact with

strange beings (aliens, fairies, machine elves, et

cetera) (Bigwood and Ott 1977; Leary 1966;

McKenna 1992; Meyer 1992).

When pure DMT is smoked or vaporized and

inhaled, the effective dosage lies around 20 mg

(although amounts as high as 100 mg are

sometimes smoked). The dosage for ayahuasca

and ayahuasca analogs ranges from 50 to 100 mg.

When DMT is injected, the typical dose is 1 mg/kg

of body weight (Ott 1993,433*).

DMT is also produced in the human nervous

system, where it appears to serve an important

function as a neurotransmitter (Barker et al. 1981;

Callaway 1996; Siegel 1995b). Neurobiologists are

as yet uncertain about the role DMT might play in

the nervous system. Hyperventilating causes the

concentration of DMT in the lungs to increase

(Callaway 1996). One physician has reported that

the release of endogenous DMT is highest at the

moment of death. It is my opinion that this

chemical messenger is responsible for the ultimate

shamanistic ecstasy, for enlightenment, and for the

merging into the "clear light of death." An experiment

in which DMT was given to practicing

Buddhists found that the subjects had experiences

and visions that corresponded to the Buddhist

teachings (Strassman 1996).

DMT has clearly inspired numerous novels in

the fantasy and science-fiction genres. The novel

Kalimantan deals with the search for a fictitious

hallucinogenic drug called seribu aso. The descriptions

of the effects of this drug agree perfectly with

the descriptions of DMT trips (Shepard 1993).

Several novels, including the Valis trilogy of the

science-fiction master Philip K. Dick (1928-1982),

also appear to represent a literary attempt to understand

the hyperdimensionality of DMT experiences

(Dick 1981a, 1981b, 1982).

Commercial Forms and Regulations

DMT occurs as a free base, an HCL, and a

fumarate. Although the fumarate crystallizes out

easily, it contains only 600/0 of the pure substance.

DMT is classified as a Schedule I drug in the

United States and is a "narcotic drug in which

trafficking is not allowed" in Germany as well as in

Switzerland (Korner 1994,38*).
