5-MeO-DMT is a potent, fast-acting, and short-lasting psychedelic compound. Many people regard it as the world’s most powerful psychoactive substance. While it can provide people with profound and life-changing experiences, it is not as commonly used as other classic psychedelics, like psilocybin, LSD, and DMT.
It is worth gaining an understanding of this compound, as its history, effects, and potential therapeutic uses are pretty fascinating. This guide will explore these different aspects of 5-MeO-DMT, as well as compare this compound with other psychedelics.

What Is 5-MeO-DMT?
5-MeO-DMT is a tryptamine psychedelic, which means it is a chemical derived from tryptophan, an essential amino acid. Other tryptamine psychedelics include psilocybin, psilocin, ibogaine, bufotenin, and DMT.
5-MeO-DMT differs from DMT (N,N-dimethyltryptamine), chemically speaking, in that the former is derived from the latter. You can see this based on 5-MeO-DMT’s full scientific name: 5-methoxy-N,N-dimethyltryptamine.
Where Can You Find 5-MeO-DMT?
5-MeO-DMT is a natural psychedelic compound. It often comes from many plant species and, most notably, one species of toad: Incilius avarius (or the Sonoran Desert Toad).
You can find the Sonoran Desert toad in arid and semiarid parts of the Sonoran Desert, in northern Mexico and the southwestern United States. Areas in the United States where it lives include the lower Colorado River and parts of California, New Mexico, and Arizona.
The Sonoran Desert toad secretes toxins (mostly steroids) from glands in its skin as a defense mechanism. The toad’s venom also contains the psychoactive substances 5-MeO-DMT and bufotenin.
It is common for people to use 5-MeO-DMT that has been extracted from this type of toad. This involves squeezing their glands and catching the spray on a piece of glass. When dried, the venom forms flaky crystals on the glass, which you can then collect for use. Vaporizing the dried venom destroys the toxins but not the 5-MeO-DMT.

Synthesizing 5-MeO-DMT
However, it is also possible to synthesize 5-MeO-DMT. And some psychedelic advocates argue that users should prefer the synthetic version over the toad-derived one for several reasons. Tim Ferriss stresses that the Sonoran Desert toad is under multiple threats, including climate change, rapid urbanization, and overcollection. Ferriss points out that synthetic 5-MeO-DMT is both affordable and scalable. As he puts it, “Why put an at-risk species in the gristmill?”
In 2019, Hamilton Morris attended the World Bufo alvarius Conference (WABC) in Mexico City (here it should be noted that the scientific name of this toad has been changed from Bufo alvarius to Incilius alvarius).
Speaking at the conference, Morris encouraged attendees to choose synthetic 5-MeO-DMT over the natural variety, based on the negative effects associated with harvesting toad secretions. He stated at the conference: “I don’t think there is a good sustainable way to milk these toads especially if this material keeps gaining popularity at the rate that it is.”

The Rising Popularity Of 5-MeO-DMT
While not as commonly used as substances like LSD or psilocybin, 5-MeO-DMT is growing in popularity, as Morris underlines. Psychedelic retreats now offer an experience with the compound. You can find many 5-MeO-DMT retreats in Mexico, for example. There are even hotels in Mexico that give people the opportunity to smoke the toad venom.
Celebrities have also come out in the open about their use of 5-MeO-DMT, including Mike Tyson, HGVT’s Christina Haack, Hunter Biden, and former NFL player Eben Britton. The journalist and author Michael Pollan also described an intense experience with the substance in his highly popular book How to Change Your Mind (2018).
Matthew W. Johnson, a psychedelic researcher at Johns Hopkins University School of Medicine, states the below.
“The current wave of popularity is really just building on the increased awareness of this compound over the last few decades. The internet has obviously played a huge role.”
David E. Carpenter, a journalist who covers trends in psychoactive substances for Forbes, points out 5-MeO-DMT’s short duration and fast onset is another reason for its growth in popularity.
Carpenter says it appeals to people seeking “a 15-minute session where you experience yourself dissolving into unitary consciousness … rather than a five-to-eight-hour rollercoaster ride on something like psilocybin-containing mushrooms.”
The Effects Of 5-MeO-DMT
As Carpenter mentions, the 5-MeO-DMT experience lasts around 15 minutes. Depending on the dosage, the experience may be shorter or longer than this.
When smoked, the onset can occur within as little as five seconds. The come-up lasts 30-60 seconds. You reach the peak of the experience in 5-10 minutes, with the coming down stage lasting 10-20 minutes. After-effects can persist for 15-60 minutes.
The effects of 5-MeO-DMT come on strong and quickly, often with a loss of physical coordination and control. This is why it’s important to take the compound in the presence of a guide, as they will help ensure your physical safety.
Unlike DMT, 5-MeO-DMT does not often include a very visual experience. The experience involves more of an intense perspective shift, characterized by physical, emotional, and conceptual effects. During the onset, anxiety or excitement may occur. Intense emotions throughout are typical, ranging from extreme fear to euphoria.
It is common for people to experience traveling to a place that is purely white, with no visuals. Users may use terms such as “void” or “nothingness” to describe this place.
Mystical experiences with 5-MeO-DMT are common, including effects such as the following.
- Ego death (the loss of your sense of self or identity), which may occur quickly after smoking the substance
- Oneness with the universe
- Being outside of time and space
- A feeling of sacredness or the “divine”
- Intense feelings of love and joy
Therapeutic Uses
Many users of 5-MeO-DMT report that their experiences with the compound have transformed their lives for the better. Scientific research is now beginning to validate some of the claims about 5-MeO-DMT’s therapeutic potential.
First, researchers have found that this potent psychedelic reliably induces mystical experiences. Other researchers have linked the therapeutic benefits of psilocybin to the compound’s ability to induce these types of experiences. By offering a deeply spiritual experience, 5-MeO-DMT may likewise be able to help people recover from mental health conditions like depression.
According to one study, a single experience with vaporizing 5-MeO-DMT can lead to reductions in depression, anxiety, and stress — as well as increases in life satisfaction and mindfulness — after the session and in the long term.
Also, the authors of the study state:
“Participants that experienced high levels of ego dissolution or oceanic boundlessness during the session displayed higher ratings of satisfaction with life and lower ratings of depression and stress.”
A separate study from Johns Hopkins found that the use of 5-MeO-DMT in a ceremonial group setting is associated with decreases in depression and anxiety. The authors found that these improvements were related to the below.

5-MeO-DMT: Clinical Research and Legal Status in 2025
Since this article was written, 5-MeO-DMT has attracted substantially more clinical attention — driven partly by its unique pharmacological profile and partly by early results suggesting it may produce effects comparable to psilocybin but in dramatically less time.
The research case. A 2019 observational study published in Psychopharmacology (n=42) found that a single 5-MeO-DMT session produced significant reductions in depression and anxiety scores lasting 4 weeks — comparable to what psilocybin achieves in multi-hour sessions, but in a 15–30 minute window. Johns Hopkins has conducted research on 5-MeO-DMT and mystical-type experiences. A 2023 Phase 2 trial by Beckley Psytech examined a synthetic 5-MeO-DMT intranasal formulation for treatment-resistant depression with promising preliminary results. Unlike toad-derived 5-MeO-DMT (which has quality control and conservation concerns), synthetic 5-MeO-DMT allows precise dosing and avoids the ethical and ecological complications of harvesting from Bufo alvarius toads.
Legal status. 5-MeO-DMT is Schedule I in the United States since 2011, meaning it carries the same legal penalties as heroin and has no legal prescription pathway. It is not covered by the same religious freedom exemptions that protect ayahuasca for certain churches, since it is not a component of their traditionally used ceremonial brews. In Mexico and several other countries it is not controlled, which is why many retreat centers offering 5-MeO-DMT experiences operate there. Oregon’s psilocybin program does not cover 5-MeO-DMT. The FDA granted 5-MeO-DMT Breakthrough Therapy Designation for major depressive disorder in 2024 for Beckley Psytech’s synthetic formulation — the same designation held by psilocybin and MDMA — which significantly accelerates the development pathway but does not constitute approval.
Safety profile. 5-MeO-DMT’s extreme intensity makes set, setting, and sober guide support even more critical than with other psychedelics. The experience is so overwhelming that many participants report complete temporary loss of self-referential consciousness — which can be profoundly meaningful or genuinely terrifying depending on preparation and context. Physical risks include elevated heart rate and blood pressure, and the same serotonergic combination risks as other psychedelics (MAOIs, SSRIs, lithium). Unregulated retreat contexts have produced reported cases of physical injury from participants thrashing during experiences without adequate support. The case for supervised settings is particularly strong with this compound.
Frequently Asked Questions
What’s the difference between 5-MeO-DMT and DMT?
Both are tryptamine compounds, but they differ significantly in experience profile. DMT (N,N-DMT, “the spirit molecule”) produces vivid, complex visual content — elaborate geometric patterns and, at high doses, richly detailed immersive environments and perceived beings or entities. 5-MeO-DMT produces very little visual content; instead it tends toward complete dissolution of selfhood — a total loss of boundaries between self and universe described as one of the most intense experiences possible. Many people who have used both consider them completely different experiences despite their chemical kinship. Both are short-acting (15–30 minutes when smoked or vaporized); both are Schedule I in the U.S.
Is 5-MeO-DMT legal?
No — in the United States, 5-MeO-DMT has been Schedule I since 2011. Possession carries federal controlled substance penalties. It is not covered by the religious freedom exemptions that protect ayahuasca for specific churches, and it is not included in Oregon’s or Colorado’s psilocybin programs. The FDA’s Breakthrough Therapy Designation (granted in 2024 to Beckley Psytech’s synthetic formulation for MDD) accelerates clinical development but does not create any current legal access pathway. In Mexico it is not scheduled, which is why retreat operators in Mexico offer 5-MeO-DMT experiences legally there. The toad species Bufo alvarius is also protected under Mexican environmental law, which has driven movement toward synthetic formulations.
How long does 5-MeO-DMT last?
When inhaled (smoked or vaporized), onset is near-immediate (seconds) and peak effects last approximately 5–20 minutes, with total duration of 15–45 minutes. This is dramatically shorter than psilocybin (4–6 hours) or LSD (8–12 hours). The brevity is one reason clinical researchers find it interesting — a potentially powerful therapeutic experience that fits in a short clinic visit rather than an all-day session. At higher doses the experience can feel much longer subjectively; time perception is severely distorted. Intranasal formulations (as in Beckley Psytech’s trials) may have a slightly slower and more controllable onset than inhalation.
What are the main risks of 5-MeO-DMT?
The intensity of the experience itself is the primary risk — 5-MeO-DMT produces one of the most overwhelming altered states of any known substance, and without adequate preparation and a skilled guide, the psychological crisis potential is high. Physical risks are similar to other psychedelics: elevated heart rate and blood pressure (relevant for cardiovascular conditions), and dangerous serotonergic interactions with MAOIs, SSRIs, and lithium. In unregulated retreat settings, physical injury from uncontrolled movements during the experience has been reported. Unlike psilocybin, which has a slower onset that allows some adjustment time, 5-MeO-DMT’s near-immediate onset leaves no preparation window once ingested — making the pre-session preparation and guide quality even more critical.

February 19, 2022 at 8:18 pmI have been researching 5Meo-DMT and I am trying to see how this interacts with Effexor XR or whether this is contraindicated as Effexor is with Ayahausca. From what I’ve researched it appears that prior to the 5Meo usage, one should be off Effexor for at least 3 weeks but there is contradictory information about. I have been taking Effexor XR for many years with good results; more recently I have researched what I stated about: namely, if one can do 5Meo and still be on Effexor. I cannot find anything definitive in any reliable source.
Any help would be greatly appreciated.
