What Is DMT?

DMT (N,N-dimethyltryptamine) is a powerful hallucinogen found in some plants and made in illegal labs. When smoked or vaped, it causes an intense trip that starts within seconds and usually ends in under an hour. DMT is also the active ingredient in ayahuasca, and it’s a Schedule I drug in the U.S.

Call 911 if someone who used DMT or ayahuasca has a seizure, chest pain or trouble breathing, or is a danger to themselves or others. For a mental health crisis, call or text 988.

What Is DMT?

DMT is a hallucinogen in the tryptamine family, the same chemical family as psilocybin, the active compound in “magic mushrooms.” Like other classic hallucinogens, it acts mainly on the brain’s serotonin receptors and changes how a person sees, hears, feels and thinks (NIDA).

DMT is found naturally in a number of plants, and tiny amounts occur in animals and humans. Scientists still don’t know what role, if any, it plays in the human body.

For centuries, Indigenous peoples in the Amazon basin have used DMT-containing plants in ceremonial brews such as ayahuasca. Today, DMT is also made in illegal labs and sold online and in person. It has no approved medical use in the U.S. (DEA).

How People Use DMT

DMT doesn’t work when swallowed by itself, because enzymes in the gut break it down (DEA). People use it in a few ways:

• Smoked or vaped. This is the most common way to use purified DMT. When it’s mixed with herbs, the blend is called changa.
• As ayahuasca. This brew combines a DMT-containing plant with a vine that contains monoamine oxidase inhibitors (MAOIs). The MAOIs block the gut enzymes, so the DMT can take effect. Learn more about ayahuasca.
• Snorted or injected. These are less common. Injecting DMT is especially dangerous.

Pure DMT forms white crystals, but street DMT is often yellow, orange or pinkish because of impurities. There’s no way to know how strong or pure a street sample is.

DMT street names

• Dimitri
• The spirit molecule
• Businessman’s trip or businessman’s special
• Forty-five-minute trip
• Fantasia
• Changa (a smoking blend)
• Ayahuasca, yagé or hoasca (brews)

DMT Effects: What a Trip Feels Like

When smoked or vaped, DMT acts within seconds. People often describe the experience as intense and hard to put into words (study).

Mental effects:

• Vivid visions, bright colors and shifting geometric patterns
• A feeling of leaving the body or entering another world
• Sensing “beings” or presences
• A distorted sense of time, space and self
• Euphoria, awe or a sense of spiritual meaning
• Overwhelming fear, panic or confusion (a “bad trip”)

Physical effects:

• Faster heart rate and higher blood pressure
• Dilated pupils
• Dizziness and loss of coordination
• Agitation
• Nausea and vomiting, especially with ayahuasca
• Chest pain or tightness
• Rapid, rhythmic eye movements

How Long Does DMT Last?

DMT is known for its short, intense trip, which is where street names like “businessman’s trip” come from. How long it lasts depends on how it’s used:

How it’s used	Effects start	Typical length
Smoked or vaped	Within seconds to a minute	About 30 to 45 minutes, strongest in the first few minutes
Injected	Within seconds	Similar to smoking
Ayahuasca (swallowed)	About 20 to 60 minutes	About 4 to 6 hours

A short trip doesn’t mean a small risk. A frightening experience can leave a person shaken, anxious or confused for hours or even days afterward.

Is DMT Legal?

DMT is a Schedule I controlled substance under federal law. The government considers it to have a high potential for misuse and no accepted medical use, and it’s illegal to make, buy, sell or possess (DEA). DMT is also a controlled substance under Florida law.

A small number of religious groups in the U.S. have won court cases allowing them to use ayahuasca in their ceremonies (source). Those rulings apply only to those groups and don’t make DMT legal for anyone else.

Researchers can study DMT with special federal approval. Early studies are looking at whether it could help treat conditions such as depression, but it isn’t approved for any medical use (research review). This section is general information, not legal advice.

Risks and Dangers of DMT

DMT isn’t safe at any dose. Its risks include:

• Dangerous behavior during a trip. Panic, paranoia and confusion can lead to falls, injuries or harm to others.
• Heart strain. DMT raises heart rate and blood pressure, which is risky for people with heart disease or high blood pressure.
• Seizures and breathing problems. High doses may cause seizures, breathing that stops, and coma.
• Serotonin syndrome. Using DMT or ayahuasca with antidepressants or other drugs that affect serotonin can cause this emergency. Signs include agitation, confusion, fever, heavy sweating, muscle twitching or stiffness and a racing heart.
• Ayahuasca drug and food interactions. The MAOIs in ayahuasca can react badly with many medicines, with stimulants such as cocaine, and with aged or fermented foods, causing a dangerous spike in blood pressure.
• Unknown ingredients. Street DMT and ceremonial brews vary in strength and may contain other substances. Serious illness, injuries and deaths have been reported at ayahuasca ceremonies (CBC).
• Pregnancy. Human safety data are lacking, and animal studies suggest possible harm to a developing baby (study).

Mental health risks

Hallucinogens like DMT can trigger lasting problems, especially in people with a personal or family history of psychosis, schizophrenia or bipolar disorder (NIDA). These problems are rare but can be serious:

• Persistent psychosis. Hallucinations, paranoia or disorganized thinking continue after the drug wears off. Learn more about psychosis.
• Hallucinogen persisting perception disorder (HPPD). Flashbacks or visual changes, such as trails or halos, come back weeks, months or even years later.

Is DMT Addictive?

DMT doesn’t usually cause the compulsive drug-seeking or physical withdrawal seen with drugs like opioids or alcohol. Research also suggests the body builds little tolerance to it, unlike many other hallucinogens.

Still, some people use DMT again and again. Repeated hallucinogen use can become a problem, especially alongside other drugs or mental health conditions, and hallucinogen use disorder is a recognized diagnosis. For a closer look, read is DMT addictive?

Getting Help for DMT and Hallucinogen Use

If DMT or other hallucinogens are affecting your mental health, relationships or daily life, help is available. The Recovery Village Palm Beach at Baptist Health treats adults 18 and older at our Lake Worth campus.

Because hallucinogen use and mental health often overlap, our dual diagnosis treatment addresses both together. Care can include residential treatment, partial hospitalization (PHP) and an intensive outpatient program (IOP) as a step-down level of care. Therapies include cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), and individual and group therapy.

The care team sets the length of stay based on each person’s needs. Learn more about DMT addiction treatment, or call (561) 340-7269 to talk with our admissions team. Check your insurance benefits.

DMT FAQ

How long does a DMT trip last?

When smoked or vaped, a DMT trip usually starts within seconds and lasts about 30 to 45 minutes, with the strongest effects in the first few minutes. As ayahuasca, effects start in about 20 to 60 minutes and can last 4 to 6 hours. After a difficult trip, some people feel anxious, shaken or confused for hours or days.

Is DMT legal in the U.S.?

No. DMT is a Schedule I controlled substance under federal law, so making, buying, selling or possessing it is illegal. A few religious groups have won narrow court rulings allowing ceremonial ayahuasca use, but those rulings don’t apply to the public.

Researchers need special federal approval to study it. DMT is also controlled under Florida law.

Does DMT show up on a drug test?

Standard drug tests don’t screen for DMT (PubChem). The body breaks DMT down quickly, and it stays in the blood for only a short time (study).

Specialized lab tests can detect DMT or its byproducts, and hair testing may show use for longer, but these tests are rarely ordered. Not being tested for doesn’t make DMT safe.

What’s the difference between DMT and ayahuasca?

DMT is the active chemical. Ayahuasca is a brew that contains DMT from one plant plus MAOIs from a vine, which let the DMT work when swallowed.

Smoked DMT hits within seconds and lasts under an hour, while ayahuasca takes longer to start and lasts several hours. The MAOIs in ayahuasca also add risks from drug and food interactions.

Does the human body make DMT?

Tiny amounts of DMT have been found in the human body, and animal studies suggest the brain can make it. Scientists don’t yet know what it does there.

Research hasn’t shown that the brain releases large amounts of DMT during dreams or near death. Natural traces in the body are very different from taking DMT as a drug.

Can DMT cause psychosis?

It can. During a trip, DMT causes hallucinations and changes in thinking that look like psychosis.

For some people, especially those with a personal or family history of psychosis, schizophrenia or bipolar disorder, symptoms can continue after the drug wears off. Anyone with lasting paranoia, hallucinations or confused thinking should get a mental health evaluation right away.
