The Mental Effects of DMT in Healthy Adults (2024 Study)

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. To keep infusion rates equal across doses, DMT was drawn into syringes for the bolus https://sober-home.org/review-and-comparison-new-beginning-recovery/ and slow-rate infusion, then saline was added to create a total of 5 ml and 15 ml, respectively. The bolus injection and saline flush were administered by a study physician, and the constant-rate infusion was delivered with a BD Alaris GH plus syringe pump (BD Switzerland Sàrl, Eysins, Vaud, Switzerland), with the infusion rate set to 30 ml/h.

Major Findings: DMT & Mental Effects in Healthy Adults (

When smoked, DMT produces brief yet intense visual and auditory hallucinations that some users describe as an alternate reality, otherworldly, or a near-death experience. People who use ayahuasca often do so as part of religious or cultural rituals. The brew contains a range of compounds that may help limit side effects and reduce the overall toxicity of DMT. This means that it is illegal to manufacture, buy, possess, or distribute the drug.

1. For example, DMT releases dopamine from presynaptic stores (Smith, 1975).
2. The 5-HT2C receptor is likely less significant in the psychedelic effects since tolerance develops to the 5-HT2C receptor (Smith, 1998).
3. 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).
4. Eben wrote a book called Proof of Heaven, which described a quasi-celestial encounter with millions of butterflies and a vision of his late sister – arising from a bout of bacterial meningitis.
5. Endogenous DMT is synthesized from the essential amino acid tryptophan, which is decarboxylated to tryptamine.

Subsequent paragraphs will examine discrimination studies assessing potential mechanisms of action of DMT. In humans administered 4 repeated doses of DMT 30 minutes apart, Strassman et al. (1996) observed no tolerance to the subjective effects of intravenous DMT as measured by the Hallucinogen Rating Scale. However, tolerance did develop to change in body temperature and other physiological factors. These findings will be discussed in more detail in the paragraph on cardiovascular effects in section 5. Mild cross-tolerance to DMT was reported in humans made tolerant to LSD (Rosenberg et al., 1964; Jenner et al., 1980).
