Psychedelic toad venom is a psychoactive substance that is secreted by the Sonoran desert toad native to Arizona.

The toad is also called a Bufo toad after its scientific name, bufo alvarius. When humans use their venom, it can cause hallucinations similar to other psychedelic drugs.

What Is Toad Venom?

The chemical name for toad venom is 5-MeO-DMT or 5-methoxy-N, N-dimethyltryptamine. This is what is extracted from the toad secretion to produce the hallucinations that people experience.

After it has been extracted, the toad venom is dried into crystals and smoked. Taking this hallucinogen is referred to as “smoking the toad” in slang.

A Brief History Of Toad Venom

No one is sure how long toad venom has been used this way. A Mexican doctor named Octavio Rettig, gave a TEDx talk at the Burning Man Festival in 2013, claiming that toad venom had been used in the rituals of the Mayan and Aztecs.

Others doubt this. Researcher Alan Davis believes it is possible that the psychedelic properties of toad venom were discovered by Ken Nelson, a reclusive North Texas man who lived in a decommissioned missile base.

As far as anyone knows, Nelson was the first person to dry the poison and smoke it in 1983.

Toad venom received a spurt of fame in the 1980s when it was reported that people were licking the Sonoran desert toad to experience a hallucinogenic high. It faded with time, probably because of the method of drug ingestion.

However, the venom came back into popularity when Dr. Octavio gave his talk at the Burning Man festival, claiming he had helped the Seri people combat meth addiction through toad venom.

He also said that the Aztec and Mayan rituals involving toad venom produced a unique language that he hoped to restore.

Whether that is true or not, toad venom has become one of the more popular psychedelic drugs available.

Effects Of Toad Venom

Toad venom takes effect in a matter of seconds to produce a powerful hallucinogenic high that can last about 20 to 30 minutes.

Short-Term Effects

It can be difficult to discern the difference between reality and hyperbole when looking at the effects of smoking toad venom.

At least one of the reasons for this could be that, as a hallucinogen, toad venom is said to break down the distinction between hallucination and reality.

Some describe it as pure awareness, and it is sometimes nicknamed the “God Molecule” by proponents of its use.

Adverse short-term effects can include high blood pressure, tachycardia, vomiting, and a response to the psychoactive properties that make hallucinations feel like nightmares.

Long-Term Effects

Flashbacks seem to be the main long-term concern of toad venom, which can be terrifying for someone who had a bad initial experience with the substance.

However, it is difficult to tell because the venom has not been studied as long as other psychedelics like magic mushrooms (psilocybin).

How Is Toad Venom Different From Other Psychedelics?

Intensity is one of how toad venom seems to be different from other psychedelics. The psychedelic experience can be as much like a nightmare as an intense state of altered consciousness.

Another way in which toad venom differs from other psychedelics is that its duration is much shorter. Toad venom lasts about 20 to 30 minutes, whereas other psychedelics, such as ayahuasca, can last for several hours.

Popularity Of Toad Venom

Recently, toad venom has found popularity with a number of celebrities, Hollywood and otherwise, who say that the psychedelic substance has given them life-changing insights.

Mike Tyson And Toad Venom

In 2021, the New York Post reported Tyson as saying that he “died” the first time that he took toad venom. This death appears to have been metaphorical, and Tyson concluded that “life and death both have to be beautiful.”

Tyson has since been on podcasts talking about his experiences with the psychedelic drug.

Other Celebrities Who Have Used Toad Venom

Tyson is not the only celebrity who has talked about the role of toad venom in his life. Christina Haack, the host of an HGTV show, said that toad venom helped her deal with anxiety.

Toad Venom And Mental Illness

These statements bring up the growing use of psychedelic drugs as a treatment for mental illness.

Ketamine, a dissociative anesthetic distinct from classic psychedelics, has FDA-approved therapeutic use via esketamine (Spravato) for treatment-resistant depression. Ayahuasca has also been used to pioneer this kind of treatment.

In a 2019 survey study published in The American Journal of Drug and Alcohol Abuse, Johns Hopkins researchers found that among 362 adults who had used 5-MeO-DMT, approximately 80% reported improvements in anxiety and depression.

Research into the duration of these benefits is ongoing. A 2023 study published in PLOS ONE found that therapeutic effects from a single 5-MeO-DMT session persisted at 4-week follow-up in participants with treatment-resistant depression, though larger controlled trials are still needed.

Toad Venom Retreats

Toad venom is a Schedule I controlled substance, which means that it has, in the eyes of the Controlled Substance Schedules, no redeeming medical value and is illegal in the United States.

However, several U.S. cities and the state of Colorado have decriminalized personal use and possession of 5-MeO-DMT and other natural psychedelics. As a result, prosecution is deprioritized even where the substance remains federally illegal.

People seeking toad venom can also get it by going to retreats in Mexico or Canada, where the substance is legal.

Is Toad Venom Dangerous?

Toad venom is not without its dangers. There have been reports of negative effects, including the death of a photographer in Spain in 2020, according to the New York Times.

Unfortunately, relatively little is known about how dangerous toad venom is. While the risks to people with pre-existing conditions related to high blood pressure and tachycardia are recognized, other risk factors are unknown.

For this reason, some retreats have paramedics standing by while the poison is administered.

Where Does This Leave The Toad?

As recently as November 2022, the National Park Service warned people against licking the Sonoran desert toad.

The need to warn parkgoers away from the toad begs the question of how the amphibian is faring under increased attention.

According to the New York Times, reports of the poaching of the toad have caused people to be concerned about the amphibian’s welfare.

Proponents of toad venom are split into two camps, some advocating the use of synthetic MeO-DMT and others saying that only the real thing will suffice.

Can You Become Addicted To Toad Venom?

Again, this is difficult to answer because of the lack of peer-reviewed research. It is possible to become dependent on some psychedelic drugs like MDMA, especially if the altered state becomes preferable to the real one.

Whether toad venom is one of those or not remains to be seen.
