DMT (N,N-Dimethyltryptamine)
A fast-acting, short-lived classic psychedelic found in many plants and produced in trace amounts in the body. Studied for depression and for understanding consciousness because its effects are intense but brief.
How it works
Activates serotonin 5-HT2A receptors, producing vivid changes in perception. When taken orally in ayahuasca, an MAO inhibitor is needed so it is not broken down too quickly.
Key facts
- Molecular weight: 188.27 g/mol
- Half-life: ~10-15 minutes
- Bioavailability: Inhaled/injected (very short); oral only with an MAO inhibitor
- Storage: Research/clinical settings only.
Dosing overview
- Typical dose: Controlled dosing in clinical studies
- Frequency: One to a few supervised sessions
- Duration: Acute effects last 5-20 minutes (longer as ayahuasca)
- Route: Inhalation or IV in research; oral as ayahuasca
Protocol notes
- Smoked or vaporized for a very short (5-20 minute) but extremely intense experience.
- In research it is sometimes given by slow IV drip so scientists can control and extend the effect.
- Taken by mouth only as part of ayahuasca, combined with a plant that stops the body breaking it down.
- People sit or lie down somewhere safe because the onset is sudden and overwhelming.
Reported benefits
- Studied for depression
- Very short experience aids research design
- Used to study consciousness
- Long traditional use as ayahuasca
Possible side effects
- Very intense, rapid onset
- Anxiety or fear
- Raised heart rate and blood pressure
- Nausea (especially as ayahuasca)
Research
- DMT for major depressive disorder (Phase 1/2a) (2023): Early trials reported rapid and meaningful reductions in depression symptoms after supervised dosing.
Community reviews of DMT
- reid664 rated it 5/5 - Brief, intense, and left me a bit fried after: I tried DMT for about 8 weeks while I was sorting recovery and stress after firefighting, and in Singapore the quiet at night made the contrast even sharper. For me it helped reset my head, but the downside was obvious, I felt mentally wiped and a bit shaky after sessions, even when the trip itself felt steady, leh.
- ruby109 rated it 5/5 - Fast, weird, and oddly useful for my head: I’m a retired firefighter on the West Coast, and I tried DMT because I wanted to see what the hype was about without turning my life upside down. I ran it for about 4 weeks, on and off, and it fit my routine better than I expected because it was so short. I wasn’t sitting there all night wrecking the next day, which matters when you’re trying to keep your head straight and still get stuff done. For me, it seemed to shake loose some mental junk and made my regular workouts feel less stale. Could just be my own experience, but I came away impressed. Five stars from me.
- dad_talia rated it 2/5 - Fast, weird, then mostly nothing for me: I tried DMT because I was curious about consciousness research and I had a stretch where I was already thinking hard about burnout from teaching and recovery after long runs in the Midwest winter. The first week, it was intense and over fast, which felt almost comical. By week 2 and 3, I noticed less dread going in, but the actual benefit faded. After a few months, it mostly felt like a short jolt with some afterglow that did not stick.
- optimizer_data276 rated it 4/5 - interesting for perspective, but low dose psilocybin did more for me long term: tried this out of pure academic curiosity, working in medicine you see a lot of rigid thinking around mood and stress and i wanted to understand the mechanism firsthand. the experience itself was intense but so short it was hard to integrate anything from it. over about 4 months of occasional use i noticed some shift in how i related to stress at work, but honestly low dose psilocybin gave me more lasting change per session for me. still glad i explored it, just wasn't my favorite tool.
- sleep_nerdy rated it 4/5 - 10 Weeks Chasing Quiet After Night Shifts: After a stretch of ugly sleep and that wired, foggy feeling from back to back shifts here in the South, I tried DMT during a ten week run, just hoping for some mental reset. For me, the big thing was how fast it cut through the noise, like my brain finally stopped arguing with itself for a minute. I felt calmer after, but ngl the intensity was a lot, and I had to respect how quick it all was.
- coastal_paddles rated it 5/5 - Fast reset for my mental noise: DMT was the first thing in a while that made my head feel quiet afterward. That was the big change for me, more than any “trip” talk. I tried it off and on for about 8 weeks, and it seemed to help me reset after long Midwest workdays.
