A bufo ceremony is a ritualized experience in which a person inhales vaporized secretion from the Sonoran Desert toad (Incilius alvarius, formerly called Bufo alvarius). The secretion contains 5-MeO-DMT, one of the most potent psychoactive compounds found in nature. The experience is intense, typically lasting 15 to 45 minutes, and produces what participants often describe as a complete dissolution of the sense of self. It has grown rapidly in popularity over the past decade, particularly in wellness and psychedelic therapy circles, though it carries significant physical and psychological risks.
What Happens During a Ceremony
The dried toad secretion is placed on a pipe or vaporization device and heated. The participant inhales the vapor in one or two deep breaths, and the effects begin almost immediately, usually within 10 to 15 seconds. A facilitator (sometimes called a practitioner or shaman) guides the session, which typically takes place in a small group or one-on-one setting.
Once the compound takes effect, participants often lose awareness of their surroundings entirely. Physical responses during the peak can include shaking, crying, laughing, screaming, or becoming completely still. Some people experience nausea or vomiting. The facilitator’s primary role is to keep the person physically safe during this window, since coordination and spatial awareness are essentially gone. Most people lie down on a mat for the duration.
The acute psychoactive effects typically resolve within 20 to 45 minutes, though a feeling of altered perception or emotional openness can linger for hours or even days. Many ceremonies include time afterward for rest and reflection, sometimes called integration, where participants talk through what they experienced.
What the Experience Feels Like
5-MeO-DMT is pharmacologically distinct from the more widely known DMT (N,N-DMT) found in ayahuasca. Where DMT tends to produce vivid visual hallucinations and encounters with perceived entities, 5-MeO-DMT is more commonly described as a “white-out,” a feeling of merging with everything or becoming nothing. Participants frequently report ego dissolution, the temporary and complete loss of personal identity, body awareness, and the boundary between self and environment.
Survey research from Johns Hopkins found that around 75% of people who used 5-MeO-DMT rated it among the top five most meaningful experiences of their lives. Many described mystical-type experiences, including a sense of unity, sacredness, and deeply felt positive mood. At the same time, the experience can be terrifying. A significant portion of participants report intense fear or panic during the onset, particularly in the seconds when the sense of self begins to dissolve. The speed of onset leaves no time to adjust; the shift from ordinary consciousness to a completely altered state is nearly instantaneous.
Why People Seek It Out
Interest in bufo ceremonies has grown alongside the broader psychedelic therapy movement. Participants most commonly cite depression, anxiety, PTSD, addiction, and existential or spiritual searching as reasons for seeking the experience. In observational studies, people have reported lasting improvements in life satisfaction, mindfulness, and reduced symptoms of anxiety and depression in the weeks and months following a single session.
A 2019 survey study found that about 80% of respondents reported improvements in anxiety and depression after using 5-MeO-DMT. These self-reported outcomes are notable but come with a major caveat: there are currently no completed, large-scale clinical trials. The existing evidence is almost entirely based on surveys and observational data, meaning it reflects the experiences of people who chose to participate and chose to report their results. People who had neutral or negative outcomes may be underrepresented.
Physical and Psychological Risks
Bufo ceremonies are not without danger, and the risks are more serious than many facilitators communicate. On the physical side, 5-MeO-DMT causes a rapid spike in heart rate and blood pressure. For people with cardiovascular conditions, this poses a genuine threat. There have been documented deaths associated with 5-MeO-DMT use, though the exact number is difficult to establish because ceremonies happen outside medical settings and reporting is inconsistent.
The compound also interacts dangerously with several types of medications. SSRIs and MAOIs, both common classes of antidepressants, can trigger serotonin syndrome when combined with 5-MeO-DMT. Serotonin syndrome is a potentially life-threatening condition where the brain is flooded with too much serotonin, causing rapid heart rate, high fever, seizures, and in severe cases, organ failure. This makes pre-screening for medications critically important, yet many underground ceremonies lack formal screening protocols.
Psychologically, the experience can destabilize people who are vulnerable. Reports of prolonged anxiety, depersonalization (a persistent feeling of being detached from yourself), and psychotic episodes exist in the literature and in community accounts. People with a personal or family history of psychotic disorders like schizophrenia face elevated risk. The intensity of ego dissolution, while often described as healing after the fact, can also be deeply traumatic, particularly without adequate preparation and follow-up support.
The Toad Conservation Problem
The Sonoran Desert toad is native to a limited range in the southwestern United States and northwestern Mexico. As demand for bufo ceremonies has surged, wild toad populations have come under increasing pressure. Harvesting the secretion involves capturing the toad and manually expressing its parotoid glands, a process that stresses the animal even when done carefully. Repeated collection from wild populations has raised serious conservation concerns, and the toad is now classified as threatened or endangered in parts of its range. In New Mexico, it is already listed as a threatened species.
Synthetic 5-MeO-DMT is chemically identical to the toad-derived compound and produces the same effects. Many advocates, including some prominent facilitators, have shifted to recommending synthetic sources to reduce pressure on wild toad populations. Others argue that the toad secretion contains additional compounds that contribute to the experience, though this claim has not been substantiated in controlled research.
Legal Status
5-MeO-DMT is a Schedule I controlled substance in the United States, making its possession, distribution, and use a federal crime. It is also illegal in many other countries, including the United Kingdom, Australia, and several European nations. Despite this, ceremonies operate in legal gray zones, often taking place in Mexico (where enforcement is minimal), in countries with less restrictive drug laws, or simply underground in the U.S.
The Sonoran Desert toad itself is also subject to legal protections in some states. In California, for example, it is illegal to possess the toad. The combination of drug scheduling laws and wildlife protections means that participating in or facilitating a bufo ceremony carries legal risk in most jurisdictions, even where enforcement is rare.
How It Differs From Other Psychedelic Ceremonies
Compared to ayahuasca or psilocybin ceremonies, a bufo experience is dramatically shorter but far more intense per minute. An ayahuasca ceremony lasts four to six hours and unfolds gradually, with waves of visual and emotional content. A psilocybin journey typically runs four to six hours as well, with a slower build. Bufo hits full intensity within seconds and resolves in under an hour. There is very little narrative content: no visions of jungles or conversations with entities, but rather a raw, overwhelming shift in consciousness that many people struggle to put into words afterward.
This compressed timeline appeals to some people and alarms others. The brevity can feel more manageable in theory, but the lack of gradual onset means there is no opportunity to ease in or adjust your mindset once the experience begins. For this reason, many experienced psychedelic therapists consider 5-MeO-DMT to be among the most challenging psychoactive substances to work with, not because the session is long, but because the intensity per second is unmatched.
