Subjective drug effects decreased in intensity shortly after the end of infusion, resolving almost entirely 20 min after the end of infusion. Subjective drug effects appeared within 1 min of the start of the bolus injection, peaked at 2 min, and settled at a slightly lower-than-peak intensity for the duration of the infusion. This was combined with a bolus loading dose aiming to achieve prolonged effects within a short time span. There was a significant dose-effect relationship for all doses, for all measured timepoints until minute 50. Plasma concentrations of DMT over time for all doses of DMT are shown in Figure 5. Acute changes in HR following continuous infusions of placebo and different doses of DMT (minutes 0–30).
While physical dependence on or addiction to DMT is not likely according to current research, some individuals may experience psychological cravings for the substance . The substance became popular in the 1960s and was classified as a Schedule I controlled substance in the 1970s due to its potential for misuse, potentially dangerous effects, and possible potential for the development of psychological dependence.

Formerly, endogenous DMT was thought to exist at concentrations too low to produce pharmacological effects, but two discoveries changed that. DMT concentrations can be localized and elevated in certain instances, for example, DMT production increases in rodent brain under stress (Barker et al., 1981). DMT is found in low concentrations in brain tissue (Saavedra and Axelrod, 1972; Christian et al., 1977; Hollister, 1977). Without more data on the recreational use of this class of compounds, it is not possible to conclude whether the synthetic hallucinogens are indeed more toxic or whether the social context may contribute to the effects.
- A study published in 2014 reported the biosynthesis of N,N-dimethyltryptamine (DMT) in the human melanoma cell line SK-Mel-147 including details on its metabolism by peroxidases.
- Street drugs mostly contain powdered DMT, whereas ayahuasca also contains harmine-related compounds, which limit toxic effects (Lanaro et al., 2015).
- For centuries, indigenous people have used DMT for healing and change, and, more recently, science is backing this up.
- Pupil diameter, heart rate, and blood pressure all peaked within 2 minutes of administration, as did subjective experiences.
- This model predicts that the sensory-altering effects of administered psychedelics are a result of the compound acting directly via neuropharmacological mechanisms in regions of the CNS involved in sensory perception.
- Though a picture of addiction might not be as clear cut as it is with certain other substances such as alcohol, opioids, and stimulants, the problematic use of any hallucinogen substance could potentially result in substance use disorder development.
Study procedures
- While the effects of DMT are usually short-lived, there are potential long-term risks.
- This page explores what DMT is, its pharmacological properties, uses, effects, and withdrawal patterns.
- Through the use of active transport mechanisms already discussed for taking DMT from blood into the brain, could potentially keep brain alive longer without the brain having to produce DMT on its own.

Adrienne Santos-Longhurst is a freelance writer and author who has written extensively on all things health and lifestyle for more than a decade. If you’re going to use DMT, take precautions to make the experience as safe as possible. salvia drug overview DMT may not produce as many side effects as other hallucinogens, but that doesn’t mean it’s entirely safe. However, things can get a little muddy when it comes to the plants that contain DMT, like those used to make ayahuasca. This means it’s illegal for recreational use, is deemed to have no current medicinal use, and has a high potential for misuse. In the United States, the DEA considers DMT a Schedule I controlled substance.
Stimulation of phospholipase A2 does not seem to directly related to the subjective effects of psychedelic compounds (Halberstadt, 2015; Kurrasch-Orbaugh et al., 2003). The 5-HT2 family of receptors are Gq/11 mediated and primarily use the phospholipase C second messenger system pathway (Brown and Tracy, 2013), but also an phospholipase A2 (Nichols, 2004). Functional selectivity on how psychedelic compounds modulate the 5-HT2 receptor family is not well understood. Subjective effects for these compounds are reported to be solely emotional, devoid of visual phenomenon common in other psychedelics such as DMT, except in rare circumstances where individual differences in biology seem to be the regulating factor (Wallach reviewed, 2009). Psychedelics and psychedelic-like compounds including MDMA, 5-MeO-DMT, DET (review Wallach 2009), and DiPT (Gatch et al., 2011; Carbonaro et al., 2015) are 5-HT2A receptor agonists.
Study drugs
In terms of its role and effect on the human body, DMT acts mainly on serotonin receptors in the brain, specifically the 5-HT2A receptor. Many who use drugs are trying to find ways to cope with their life or mental health concerns. The effects of DMT are very short-lived, which differs from other psychedelic drugs like LSD or psilocybin. DMT is an illicit hallucinogenic drug that produces intense, short-lived psychedelic experiences characterized by vivid visual distortions and altered perceptions of time. Short-acting psychedelics like DMT and 5-MeO-DMT show rapid and sustained antidepressant effects in treatment-resistant depression, potentially offering a more scalable alternative to psilocybin, though larger controlled trials are needed to confirm efficacy. Under these conditions, notions of receptor selectivity are moot, and it seems probable that most of the receptors identified as targets for DMT (see above) participate in producing its psychedelic effects.
How long does DMT last? Effects on the body and more
Participants were asked to not consume any alcoholic drinks 48 h before each study visit, and to not consume any illicit drugs 2 weeks before their first study visit until 2 weeks after their last study visit. The data for this dose is not included here as it was not repeated across participants, induced negligible psychological effects, and was not intended for analyses. Four dose levels of a combination of an IV loading bolus dose followed by a constant-rate infusion were tested, with the aim to induce and sustain moderate-to-high intensity of effects over 30 min, while silver pines restaurant maintaining psychological safety (i.e., low levels of anxiety). The study was conducted under a Home Office licence for research with Schedule 1 drugs. This could make extended DMT a valuable tool in conjunction with therapy, to tailor the psychedelic effects to the individual needs of each patient and their clinical condition, as well as for consciousness research, whereby the intensity of the DMT experience can be adjusted according to specific hypotheses and research questions.
Subjective intensity of effects was assessed acutely via experience sampling from 8 min prior to 52 min after the start of the bolus injection. To keep infusion rates equal across doses, DMT was drawn into syringes for the bolus and slow-rate infusion, then saline was added to create a total of 5 ml and 15 ml, respectively. The following infusions initially followed the lowest calculated dose regimen, with the first subject receiving a bolus dose of 6 mg of DMT fumarate, followed by a constant rate infusion of 0.63 mg/min, corresponding to projected low doses according to previous research (Strassman and Qualls, 1994). Different dose regimens were simulated based on a separate population pharmacokinetic reanalysis of data from a previous study (Strassman and Qualls, 1994), yielding new two-compartment model parameter estimates (unpublished). The main goal of the study was to provide first steps towards establishing infusion parameters for maintaining a steady state of DMT effects for a chosen length of time.
Long-Term Effects of DMT
If you or a loved one is using DMT, it’s important to understand the slang terms to identify drug use and seek treatment if it negatively affects your well-being. Though the drug is not viewed as addictive, abusing it can have serious short- and long-term effects. A crucial aspect of treating drug abuse involving DMT is addressing the behavioral aspects of substance use. Over time, a psychological desire for the drug can develop. However, more research is needed to understand the addiction potential of DMT.
Other psychedelics such as (+/-)DOI, d-LSD, and 5-MeO-DMT, and non-psychedelics such as R(+)lisuride, (+/-)MDMA and amphetamine also stimulate cAMP production through their effects at rTAAR1. Another indication that DMT does not act directly at dopamine receptors is the lack of adenylate cyclase activity in the dorsal striatum of rats (von Hungen et al., 1975). In addition, activation of sigma-1 receptor by DMT may lead to potentiation of NMDA receptors (Cozzi et al., 2009). Further, mGluR2 knockout mice showed little or no head twitch following 2,5-dimethoxy-4-iodo-amphetamine (DOI), and some signaling was disrupted, which may mean that mGlu2 can police dogs sniff out nicotine receptors are necessary for hallucinogenic activity (Moreno et al., 2011).
DMT, also known as dimethyltryptamine, is a powerful hallucinogenic substance that produces intense psychological effects. Admissions navigators are available 24/7 to discuss the various levels of addiction treatment offered, rehab payment options, and check if your health insurance covers rehab. Typically, individuals who have developed a substance use disorder require focused and lengthy interventions in order to help them function normally without using drugs or alcohol. At the time of this writing, it is not clear if extremely high doses of DMT produces toxic effects. Risk of such events increases with higher doses of DMT and polysubstance use—the use of more than one substance at a time.
The hallucinogenic and psychoactive effects are thought to bring spiritual insight. It has no medical uses and a high potential for abuse. In the US, DMT is classified as a Schedule I drug by the Drug Enforcement Administration (DEA). The synthetic version works quickly and produces effects within 5 to 10 minutes, lasting 30 to 45 minutes. The plant-based tea takes 20 to 60 minutes to produce effects lasting 2 to 6 hours.
It is likely that most adverse effects of hallucinogens are psychological effects, such as intense fear, paranoia, anxiety, grief, and depression, that can result in putting the user or others in physical harm or danger (Carbonaro et al., submitted). In the late 1990s, Rick Strassman conducted the first human research with hallucinogens in 20 years, examining the physiological effects and self-reports from people receiving DMT in carefully controlled settings (Strassman et al., 1994; 1996). DMT is one of the major psychoactive compounds found in various shamanistic compounds (e.g., ayahuasca, hoasca, yagé) used in South America for centuries (Pochettino et al., 1999) and has, more recently found its way into Europe and North America as a recreational drug (Tupper, 2008). The use of drugs in settings like this can be dangerous and result in adverse events and fatalities. There is no specific selection of music that is meant or certain experiences with hallucinogens. Some people who use hallucinogens include music listening with the expectation that the music will help provide a better experience.
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. At best, sigma-1 receptors may partially mediate the subjective effects of DMT (see review by Su et al., 2009). DMT partially blocked the discriminative stimulus effects of phencyclidine, which produces hallucinations through its actions at NMDA receptors (West et al., 2000).
Immediate Effects of DMT
These insights are vital in discussing the broader effects of DMT, aligning with the question of what are the long-term effects of dimethyltryptamine (DMT)? The complexities of DMT usage, including the nuanced balance of therapeutic potential and tolerance, emphasize the importance of responsible usage and monitoring in clinical settings. It is important to note that while tolerance can develop, DMT does not cause a formal withdrawal syndrome, unlike other substances. According to Medical News Today and NCBI, the risk of addiction for DMT remains low, but it is essential to consider how tolerance affects dosing. As interest in DMT (dimethyltryptamine) grows within the medical and social fields, understanding its addictive potential becomes increasingly relevant.

We recognise the continued connection of First Nations people to the land, the waterways and to community and kin, and pay respects to Elders past and present. If your use of DMT is affecting your health, family, relationships, work, school, financial or other life situations, or you’re concerned about someone else, you can find help and support. Polydrug use is a term for the use of more than one drug or type of drug at the same time or one after another. Reports suggest that DMT does not produce any tolerance, and there is low potential for dependence to occur.13
