What is the science of 5-MeO-DMT?
Smoking 5-MeO-DMT induces a short but intense psychedelic experience or ‘trip’, with hallucinogenic effects that are significantly stronger than those induced by DMT (the primary psychoactive molecule found in ayahuasca). Despite this, the difference between 5-MeO-DMT and DMT is just a single Methoxy group, and it is structurally similar to other psychedelic drugs such as psilocybin and DMT.
Once vaporised and inhaled, 5-MeO-DMT crosses the blood brain barrier very quickly. It shares a similar chemical structure to the neurotransmitter serotonin, which allows it to fit into and activate serotonin receptors in the brain, most notably the 5-HT2A subtype. Human pharmacology also points to a second receptor playing a meaningful role alongside 5-HT2A, called 5-HT1A, and this dual receptor action is thought to shape the particular character of the experience. Stimulating these receptors produces the psychedelic state, including hallucinations, and can affect mood and body temperature.
Part of why 5-MeO-DMT feels so sudden, intense, and short lived comes down to how quickly it moves through the body. Inhaling it delivers the drug to the brain almost immediately through the lungs, and it is then broken down rapidly by an enzyme called MAO-A. This fast breakdown is the main reason the experience is so brief, but it is also exactly why combining 5-MeO-DMT with anything that blocks MAO enzymes is so risky, a point covered in more detail below.
What are the risks?
Sleep disturbances, persistent anxiety and panic attacks have been reported in some individuals after even a single experience with 5-MeO-DMT. Unwanted or overwhelming realisations can be difficult for some people to integrate afterwards, and some accounts describe psychological disturbances or a resurfacing of effects lasting for weeks after use. Using a low, precisely measured dose can help avoid unexpected or overpowering effects.
The physical risks during a session are real but usually manageable with the right precautions. 5-MeO-DMT can raise heart rate and blood pressure, so anyone with cardiac problems should avoid it, and because it is most commonly smoked, anyone with a lung condition or asthma is at higher risk of adverse effects. In practice, though, the bigger risk is behavioural rather than purely physical, given that the peak of the experience can arrive abruptly, and can leave a person disoriented, agitated, vocalising, or briefly unable to coordinate their movements. This is exactly why the environment and the people around you during a session matter so much, covered further under Harm Reduction.
People predisposed to or living with schizophrenia or psychosis might experience an onset or worsening of symptoms from 5-MeO-DMT use.
How might the drug make you feel?
5-MeO-DMT is a relatively short-acting psychedelic drug and the ‘trip’ usually lasts less than 30 minutes when smoked, and up to 45 minutes when insufflated. When vaporised and inhaled the effects begin almost instantaneously, which means it is very important to be in a safe and comfortable environment to avoid accidents. In supervised research settings using an inhaled synthetic formulation, most effects and monitoring were completed within 60 to 90 minutes from dosing.
Users often report overwhelmingly intense experiences which can sometimes be difficult to remember. Accounts of mystical union, feelings of non-duality and experiences of a transpersonal nature are not uncommon. Often uncomfortable bodily sensations such as a rapid heart rate, nausea and pressure in the chest can be present.
The alterations to perception as a result of taking 5-MeO-DMT often include auditory and visual hallucinations, internal scenes, time perception distortions and cognitive and/or emotional shifts. Some users report that 5-MeO-DMT is less visually intense than NN-DMT.
Similar to other psychedelic drugs like psilocybin and LSD, experiences can range from being euphoric and spiritually significant to dysphoric and psychologically scarring.
Is 5-MeO-DMT addictive, and what are the long-term effects?
A study of 5-MeO-DMT users concluded that it is generally ‘used infrequently, predominantly for spiritual exploration’ and ‘has low potential for addiction’. In that sample, 82% reported using 5-MeO-DMT for spiritual or healing/psychological purposes, indicating that it is not a substance which is commonly used recreationally. Additionally, the majority of the sample indicated that they used it less than once a year, with the majority of use taking place in ceremonial or supportive contexts. Therefore, compulsive re-dosing and addictive behaviour patterns are unlikely to be seen with 5-MeO-DMT.
Harm Reduction and Drug-Drug Interactions
5-MeO-DMT is active at doses as small as 3mg, so weighing the dose carefully with a precise scale is essential to avoid accidental overdose. 5-MeO-DMT in moderate to high doses will often leave the user incapacitated, so it is important to have someone present to prevent an individual from injuring themselves if they start moving around. Because of this, it is also advisable to be aware of the environment in which it is consumed, avoiding obvious hazards such as bodies of water and steep drops.
Occasionally, effects can vary from abnormal vocalisations and unusual body movements to complete unresponsiveness. Therefore, the person accompanying a 5-MeO-DMT user should know how to place someone in the recovery position, as vomiting is sometimes reported. Bear in mind that unconsciousness, along with breathing difficulties, is a sign of overdose and should be monitored.
Although 5-MeO-DMT is sometimes included in South American ayahuasca recipes, it is generally considered dangerous to combine with any MAOI, and this combination has been linked to fatalities. 5-MeO-DMT is cleared from the body largely via MAO-A, so blocking that enzyme, whether through ayahuasca's harmala alkaloids, certain antidepressants classed as MAOIs, or other MAO-inhibiting substances, can lead to dangerously elevated drug levels, severe overheating and serious autonomic instability.
Caution is also warranted with SSRIs. Research combining 5-MeO-DMT with SSRI antidepressants exists only in a tightly controlled clinical trial context, and even there the effect on intensity and tolerability is described as uncertain and specific to the exact formulation and protocol used. Outside of that kind of supervised setting, combining 5-MeO-DMT with SSRIs should not be assumed to be predictable or safe.
Medical Uses
There is research suggesting 5-MeO-DMT could be associated with improvements in anxiety and depression. It is sometimes used as an adjunct to ibogaine therapy in the treatment of addiction, possibly because it appears to down-regulate a receptor involved in the brain's reward mechanism for drug use. Cells treated with 5-MeO-DMT have also shown responses similar to those seen with antidepressant medication, though further research is needed to properly investigate any antidepressant potential. There have also been suggestions it could help researchers understand the neurobiological basis of hallucinations and support antipsychotic drug development.
Survey-based research from Johns Hopkins University has added to this picture, finding that naturalistic use of 5-MeO-DMT was associated with significant, self-reported and lasting improvements in depression, anxiety and overall life satisfaction, with around 80% of participants rating the experience among the most personally meaningful of their lives.
Formal clinical development is now underway and moving faster than for most other psychedelics at this stage. GH Research's synthetic, inhaled formulation has progressed through Phase I safety and tolerability studies into a Phase 2b trial in treatment-resistant depression, which met its primary endpoint: a placebo-adjusted reduction in depression scores at day 8, ultra-rapid remission in more than half of patients by day 8, and continued remission in around three-quarters of patients at six months, all with infrequent dosing. On the strength of these results, the FDA lifted a clinical hold on the programme in early 2026, and a large-scale global Phase 3 trial is expected to begin the same year.
Myths and Misconceptions
5-MeO-DMT is the same as N,N-DMT
There is the potential for 5-MeO-DMT to be confused with N,N-DMT, a mistake which can be potentially problematic due to 5-MeO-DMT being 4-10x more potent than N,N-DMT and having a lower toxicity threshold. For more information on N,N-DMT, see our DMT Drug Information page. Home testing kits are available to buy online which can distinguish between the two. Always start with low doses to be safe.
You need to lick the toad to get high
There is a popular myth regarding ‘licking’ toads to get high. This is dangerous with Bufo Toads as Bufotoxin contains ‘digoxin-like cardiac glycosides’ which can be fatal. There have been reports of poisonings and even deaths from the ingestion of Bufo Toad toxins by humans.
History and Forms
5-MeO-DMT was first synthesised in 1936 by Japanese chemist Toshio Hoshino, making it one of the earliest tryptamines characterised in a laboratory, though its psychoactive properties were not recognised until decades later.
Bufo Alvarius Toad (Colorado River Toad)
As a defence mechanism, the Colorado River toad secretes a white, milky substance called bufotoxin from glands behind its eyes. When dried, this secretion contains up to 30% 5-MeO-DMT by mass, alongside other compounds such as bufotenine, DMT, NMT, DET, N-methylserotonin and bufogenin. This natural source was documented in the 1990s by ethnobotanist Wade Davis and chemist Andrew Weil, and modern recreational and ceremonial use of toad venom, particularly smoking it, spread through the American Southwest and northern Mexico from the 1980s onward, popularised in large part by a widely circulated 1984 pamphlet describing the practice. That growth in popularity has since raised real ecological concerns about the sustainability of wild toad populations. There is no evidence of any difference between synthetic 5-MeO-DMT and the compound secreted by the toad, but natural secretions vary considerably in potency from sample to sample, which makes accurate dosing harder and adds an extra layer of risk given how steep the dose response curve already is.
Synthesised 5-MeO-DMT
5-MeO-DMT is most commonly consumed in the form of a synthetic white, crystalline powder. Typical doses of 5-MeO-DMT are very small, typically 5mg, so care should always be taken by using accurate scales and researching the appropriate doses. 5-MeO-DMT in this form is typically either vapourised in a pipe and inhaled or less commonly insufflated (snorted).
Anadenanthera seeds (Yopo)
Some trees under the genus Anadenanthera contain 5-MeO-DMT. There is a long history of use of these seeds as shamanic snuffs in South America. Once the seeds have been toasted they are ground, sometimes mixed with other materials such as Ash and Tobacco, and forcefully blown up the nose of a user via a tube.
Ayahuasca
Ayahuasca is a traditional tea, originating from South America. It is made from a mixture of psychedelic plants and a vine containing a mono-amine oxidase inhibitor. The MAOI prevents gut enzymes from breaking down the psychedelic components of the leaves, making them orally active. Some Ayahuasca recipes include 5-MeO-DMT containing plants, however, this combination has been shown to be fatal, and there is evidence to show that mixing 5-MeO-DMT with MAOIs can be potentially dangerous.
