Mike Tyson has described his 5-MeO-DMT experiences in enough interviews and public statements that the outline is clear. He smoked the venom of the Sonoran Desert toad — Incilius alvarius, which secretes 5-MeO-DMT — and described dying, meeting God, and coming back different. He has said it reduced his aggression. He has said it humbled him. He has said he was nothing.
These are his words, accurately reported. They describe the compound's effects with more accuracy than most clinical summaries do. What they do not describe is what your experience will be — or what is required before and after a ceremony for it to produce anything lasting.
The active experience lasts 20–45 minutes — not 2–3 hours, not a full day. Absolute contraindications include current SSRIs, SNRIs, MAOIs, and lithium, and a personal or first-degree family history of psychosis. The experience amplifies what is present. It does not deliver what you hoped for; it delivers what is needed.
What Mike Tyson has said about 5-MeO-DMT
Tyson has discussed his experience with 5-MeO-DMT — specifically the venom of Incilius alvarius, the Sonoran Desert toad — across multiple interviews and appearances since approximately 2019. The account is consistent across its major points: he smoked the venom, lost the ordinary sense of himself entirely, and encountered something he has described variously as death, God, and nothingness. He has credited the experience with changing his relationship with aggression, with other people, and with himself.
He has described returning to the medicine more than once — not as a one-time event but as a repeated practice. He has also been candid that the experience is not pleasant in the conventional sense. The dissolution of the ordinary self is not comfortable. He has described it as something that happened to him rather than something he chose in the way one chooses a supplement.
This is useful. Most public accounts of psychedelic experiences — celebrity or otherwise — sanitise the difficulty. Tyson's accounts do not. He describes something demanding, disorienting, and in his account, necessary. That aligns with what practitioners observe.
What his account captures accurately
Three things Tyson's public account describes accurately about 5-MeO-DMT:
First, the medicine is not calibrated for a pleasant outcome. The ego dissolution 5-MeO-DMT produces — what neurological research identifies as acute suppression of default mode network activity — is not relaxation or euphoria. It is the temporary disappearance of the boundary between self and environment. That is not a comfortable experience for most people, regardless of how they have been briefed. Tyson has not claimed it is pleasant. He has claimed it is useful. The distinction is important.
Second, his account of returning to the medicine multiple times reflects something practitioners consistently observe: a single ceremony produces an experience. Multiple ceremonies, integrated over time, produce something more durable. The 20–45 minute active window is short. The integration work that follows — what is done with what the medicine surfaced — is the part that determines the outcome.
Third, the frame matters. Tyson has discussed his experiences within a frame of spiritual significance, not clinical treatment. What he encountered, he understood as contact with something beyond the ordinary self. That framing — approaching the medicine as something other than a pharmaceutical intervention — makes the experience more navigable for most people. Someone who arrives expecting something clinical and contained typically finds the actual experience significantly harder to hold.
What celebrity accounts leave out
Celebrity accounts of plant medicine do several things that don't serve the people reading them. They remove the preparation context — what the person did before the ceremony, what support they had, what they were ready for. They remove the integration context — what happened in the weeks that followed, what structural changes were made, what ongoing support was in place. They present the dramatic moment as if that moment is the medicine.
The medicine is not the 20–45 minutes. The medicine is the entire process: screening, preparation, the ceremony itself, and the integration period that follows. A 20–45 minute 5-MeO-DMT experience administered without structure, preparation, and integration support is not the same thing as a properly conducted ceremony. The compound is the same. What surrounds it determines whether the experience produces anything durable.
The person who comes expecting the account Tyson described — profound, revelatory, life-changing — and who arrives having done no preparation, with no integration plan, and seeking an experience rather than a process, tends to have a harder time during ceremony than expected and nothing lasting to show for it afterward. The medicine does not deliver what you hoped for. It delivers what is needed. Those two things are not always the same, and the gap between them is navigated through preparation and integration — not by the experience itself.
This is not speculative. Practitioners consistently observe that the people who come seeking an experience — something to talk about, a shortcut to insight, a way of feeling something without doing the sustained work of change — are the people who leave most disappointed. The medicine identifies this. It delivers what is needed, which is often not what was sought.
Why 5-MeO-DMT is not what most people expect
5-MeO-DMT is not a lighter version of ibogaine. It is shorter, not easier. The intensity of ego dissolution in 20–45 minutes produces its own demands, and the absence of narrative content — no biographical review, no visual sequences, no memory retrieval — makes integration harder for many people, not simpler.
Ibogaine produces an experience that typically contains content: memories, themes, patterns specific to that person's life. There is material to work with in integration. It is demanding material, but it is identifiable. 5-MeO-DMT produces something closer to a complete dissolution of the framework through which content is organised. What remains afterward is not nothing — but it is not narrative, either. Translating it into something workable requires different integration approaches, and the timeframe is not more forgiving because the acute experience was shorter.
The full programme — screening, preparation, ceremony, and supervised recovery — spans 1–2 days on-site. Integration coaching in the weeks following costs $150–300 CAD per session at Transcend. Read more about what 5-MeO-DMT therapy involves and how it differs from ceremony without structure.
What the research shows
The evidence base for 5-MeO-DMT is preliminary compared to ibogaine. A 2019 survey of 362 naturalistic users published in Frontiers in Psychiatry documented self-reported reductions in depression and anxiety in the weeks following 5-MeO-DMT use. A separate 2019 study published in Psychopharmacology found sustained enhancement in measures of life satisfaction and mindfulness-related capacities following a single ceremony. These findings are correlational and self-reported. The direction is consistent; the evidentiary weight is not comparable to a randomised controlled trial.
For ibogaine specifically, the strongest current evidence is the 2023 Stanford study published in Nature Medicine, which documented 88% reductions in PTSD symptoms, 87% in depression, and 81% in anxiety at one month in 30 special operations veterans with treatment-resistant conditions. 5-MeO-DMT and ibogaine are different compounds with different mechanisms — this data does not transfer between them. What it establishes is the legitimacy of the general territory. See the Stanford study on ibogaine and TBI for the full clinical picture.
Who is not an appropriate candidate
Absolute contraindications for 5-MeO-DMT ceremony:
- Current SSRIs or SNRIs without a completed supervised taper. Combining 5-MeO-DMT with active serotonergic medications creates conditions for serotonin syndrome, which can be fatal. This is not a caution to weigh. It is a hard contraindication with no exceptions.
- Recent MAOI use, including ayahuasca. MAOIs (harmine and harmaline in ayahuasca) interact with 5-MeO-DMT to create the same serotonin syndrome risk. A minimum of two weeks after the last ayahuasca ceremony is required, confirmed with the provider.
- Personal or first-degree family history of schizophrenia or psychosis-spectrum disorder. The risk of precipitating or exacerbating psychosis with 5-MeO-DMT is real. A first-degree family member with schizophrenia is a contraindication even in the absence of personal psychiatric history.
- Lithium. Absolute contraindication.
- Pregnancy.
- Acute psychiatric crisis. The experience amplifies what is present. Crisis does not become clarity through 5-MeO-DMT.
And someone seeking a shortcut — an experience rather than a process — is not ready. The 20–45 minute ceremony is not the thing that changes a life. The preparation before and the integration after are what make the ceremony produce anything durable. Arriving without those in place is not a workaround. It is a different thing entirely.

Is this right for you?
If you are considering 5-MeO-DMT ceremony because you have read about Tyson's experience — or any other public account — the question is not whether the medicine can do what those accounts describe. It can. The question is whether the process is one you are prepared to enter, and whether the conditions that would make it productive are in place before you arrive.
That is the purpose of the screening conversation. We respond to every application personally within 2–3 business days.
