While it may have some potential mental health benefits, more research is needed to explore these effects. Many people who have taken DMT who are otherwise healthy report hallucinations, connections, and psychedelic experiences similar to those of people who have had actual near-death experiences. DMT is a Schedule I controlled substance in the United States, meaning it’s illegal to use recreationally.

Psychotherapeutic Applications of DMT
Supporting the role of sigma-1 receptor is that the SSRI fluvoxamine, has sigma-1 receptor agonist properties with higher affinity than DMT. Fluvoxamine works better with patients suffering from psychotic depression compared to antidepressants without sigma-1 receptor agonist properties (Stahl, 2008). Selective sigma-1 receptor agonists do not cause psychotomimetic effects in animals. At best, sigma-1 receptors may partially mediate the subjective effects of DMT (see review by Su et al., 2009). N,N-Dimethyltryptamine (DMT) is an indole alkaloid widely found in plants and animals.
Additional Side Effects of DMT
An approach gaining increasing interest within the last decade is to examine interacting roles of serotonin and glutamate in mediating the effects of DMT. Of particular interest are the roles of group II metabotropic glutamate receptors (mGluR2/3), the NMDA receptor, and 5-HT2A receptors in modulating the levels of glutamate in the synapse. These group II glutamate receptors (mGluR2/3) may also be potential target sites for mediating hallucinogenic effects (Gonzalez-Maeso et al. 2007, 2008; Delille et al. 2012; Moreno et al. 2011; Winter et al. 2004). Head twitch response in rodents is thought to be a 5-HT2A receptor-mediated behavior produced primarily by psychedelics, although it is likely that other receptors play a role in this behavior, including 5-HT2C and glutamatergic receptors. Like other classic psychedelics, DMT does induce this head twitch response in C57Bl/6 mice, which is blocked by 5-HT2A inverse agonist, MDL (Carbonaro et al., 2015).
- These compounds have been variously reported in tissue, blood and urine samples.
- After acute administration striatal dopamine synthesis was increased, yet there was no effect on steady state conditions.
- There has also been interest in the role of INMT and DMT biosynthesis in maturation and development.
Conjecture regarding endogenous effects
Data from this survey indicates use has increased over time, with usage rates similar to methamphetamine. Research from the 2021 Global Drug Survey found that 7.4% of respondents reported microdosing with DMT. Microdosing is the practice of taking small doses of a drug to promote insight and creative thinking. When consumed as a brew in the form alcohol and anxiety of ayahuasca, the dose is between 0.6—0.85 mg for every kilogram of liquid. Effects begin within 60 minutes, peak after 90 minutes, and disappear in approximately 4 hours. Set is how you feel before you take the drug, what expectations you have, your previous experience with mind-altering drugs, any stress or anxiety you may be feeling.

Whether or not the sigma-1 receptor plays a significant role in the psychedelic effects of DMT, it may still play an important role in other physiological mechanisms. Sigma-1 receptors agonists are potentially neuroprotective via several mechanisms (see review Frecska et al., 2013). DMT reduced inflammation ostensibly via sigma-1 receptor (Szabo and Rajnavdgyi, 2014), and can induce neuronal plasticity, which is a long-term recuperative process that goes beyond neuroprotection (Ruscher et al., 2011; Tsai et al., 2009; Kourrich et al., 2012). Sigma-1 receptors can regulate cell survival and proliferation (Collina et al., 2013), thus if DMT is an endogenous agonist, this may explain physiological relevance and importance of why DMT has 3-step uptake process. It is unknown whether the typically used 5-HT2AR antagonists ketanserin and/or risperidone have any antagonist effects of TAAR as well. This is an area where more research needs to be done to fully understand the importance of TAARs and psychedelic effects.
How Safe Is DMT?
Another alternative that may assist in the ability to use lower doses and to prolong the effect of the DMT administered, however, may be the use of a deuterated analog. In the United States, the DEA considers DMT a Schedule I controlled substance. This means it’s illegal for recreational use, is deemed to have no current medicinal use, and has a high potential for misuse. Increased heart rate and blood pressure are both side effects of DMT, which can be bad news if you already have a heart condition or high blood pressure. Experts have suggested other receptors in the brain may also play a role, such as the sigma-1 receptor, or that a presently unknown hallucinogenic receptor may be at work. Smoking is favored because taking DMT orally does not lead to a psychedelic experience.
Similarly, DMT was thought to be neurotoxic, but more recent research suggests that DMT may actually be neuroprotective (Frecska et al., 2013). The first phase of the first clinical trial of DMT is complete, alcohol-related deaths what to know and it hasn’t seen any significant negative effects on well-being so far. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.
In their study, the role of 5-HT2A agonism in DMT-induced cellular and behavioral effects was examined in both cell-based and 5-HT2A knock-out mouse models. It was reported that “DMT binds to 5-HT1A, 5-HT1B, 5-HT1D, 5-HT2A, 5-HT2B, 5-HT2C, 5-HT5A, 5-HT6, and 5-HT7 receptors with affinities from 39 nM to 2.1 μM” (Keiser et al., 2009). Nonetheless, it was observed that DMT was not only a potent partial agonist at 5-HT2A but also that the DMT-induced head twitch response, a common measure of hallucinogenic activity, occurred only in wild-type mice but not in 5-HT2A knockout mice.
This sequence of events formed the link between modern science and the historical use of many DMT-containing plants as a cultural and religious ritual sacrament (McKenna et al., 1998), their effect on the psyche and the chemical structure of N, N-dimethyltryptamine. Tryptamines are naturally occurring compounds found in certain apixaban eliquis plants and animals. Evidence shows that DMT is produced in mammalian brains, but research has not yet confirmed the presence of DMT in the human brain. Anecdotally, many users report taking the drug to attain spiritual insight. Scientific data suggests its effects on the brain might mimic those of a near-death experience.
One thing is for sure, the administration of this chemical is capable of inducing extraordinary and significant—often spiritual—experiences in human beings. In summary, many aspects of the experience can differ greatly depending not only on the specific agent used but also on how the substance is administered—even though these chemicals are all closely related and may act similarly in the brain. Remember, serotonin is another closely related chemical, yet it does not produce even close to the same type of effects in humans. That being said, scientific investigations on psychedelics were indeed thankfully finally allowed to resume in the 1990s – first with Dr. Strassman’s DMT studies and then with many other substances and researchers following suit.
The experience can be so powerful that users may have difficulty processing and integrating the “trip” into real life. Because DMT can mimic a near-death experience, some people may find using the drug traumatic and upsetting. 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. If you take DMT along with other drugs that also change the serotonin levels in your brain, it could cause bad side effects.
DMT is naturally found in some plant species and combined with other plants to produce a brew called ayahuasca, which is consumed in spiritual ceremonies in several South American cultures. If taken in the ayahuasca form, the experience can last anywhere between two and 15 hours, with four to six hours being the average duration for most people. DMT can be taken in many forms, but most typically it is either taken in the ayahuasca brew or smoked as a powder. The powder form will produce a short-lasting but intense trip, and the ayahuasca brew will produce a long-lasting experience.
