Single Dose of DMT Rapidly Reduces Symptoms of Major Depression (sciencealert.com) 75

In a small double-blind clinical trial, a single intravenous dose of DMT produced rapid and clinically meaningful reductions in symptoms of major depressive disorder within a week, with effects lasting up to three months in some patients. "Unlike psilocybin and lysergic acid diethylamide ( LSD), whose effects can last for hours, intravenous DMT has a half-life of around five minutes," notes ScienceAlert. "Its psychedelic effects are correspondingly brief, potentially making it more practical to administer in clinical settings." From the report: "A single dose of DMT with psychotherapeutic support produced a rapid, significant reduction in depressive symptoms, sustained up to three months," writes a team led by neuroscientists David Erritzoe and Tommaso Barba of Imperial College London. [...] They recruited 34 participants with major depression and divided them into two groups of 17 for a double-blind, placebo-controlled trial.

In the first stage of the trial, one group received an intravenous dose of DMT, while the other received an active placebo. Neither the researchers nor the participants were informed which participants received the DMT. The doses took around 10 minutes to administer, and a therapist sat with each participant to ensure comfort and safety while the psychedelic effects were active, remaining silent throughout the treatment. The treatment was generally well tolerated. Most side effects were mild to moderate, and included nausea, temporary anxiety, and pain at the injection site. No serious adverse events related to the treatment were reported, although brief increases in heart rate and blood pressure were observed immediately after dosing.

In the second, open-label stage, two weeks after the first dose, all participants were given the opportunity to receive a dose of DMT. Participants were assessed before and at intervals after each dose using the Montgomery-Asberg Depression Rating Scale. Just a week after the first dose, participants who had received DMT had improved scores compared to the placebo group, and improvements were sustained during follow-up assessments.

Two weeks after the first dose, the participants who received DMT scored about seven points lower, on average, than those who received a placebo. On this commonly used clinical scale, a drop of that size is generally considered a meaningful reduction in symptom severity. There was no significant difference between patients who received one or two doses of DMT, suggesting a single dose may be sufficient. These effects persisted for up to three months, and some patients remained in remission for at least six months following the treatment.
The findings have been published in Nature Medicine.

    For those, like me, who were crying out for the summary to say what DMT is, it's the main active psychedelic of ayahuasca.

    • Weirdly though, DMT is somewhat more likely to make you see aliens. Ayahuasca is much more likely to feel the presence of the holy mother, or see rainbow DNA, or just vomit.

      Admittedly I've no idea what that is until I googled it, not exactly something you'd commonly find in Australia or even the UK...

      However it joins a long history of psychedelics and other mild narcotics in being quite effective in treating depression. However drugs like marijuana, LSD and likely this one are outright banned in favour of harder drugs to treat depression and other illnesses because drugs are baaaaad MKaaaay.

      • LSD is being studied for medicinal effects (and has been for a looooong time) and Marijuana is outright legalized anyways - or at least can be approved for medical use - in the majority of the US. Some see some beneficial effect but if they were miracle drugs we would know by now. A big new study on microdosing came out just a couple weeks ago, finding only a little benefit unfortunately.

    Unlike ayahuasca, DMT is not nearly as likely to make you vomit.
    • Unlike ayahuasca, DMT is not nearly as likely to make you vomit.

      From what I've read, DMT has quite varied effects based on the amount. And probably the source, since DMT is present in many natural sources.

      As far as the vomiting, let's be a little more honest. Trying to compare a DMT study done in a controlled environment with known dosages to the average ayahuasca trip is a bit like comparing a professional medical autopsy in a hospital to roadkill. Results may vary? No shit. The drunk guy who introduced you to the ayahuasca sommelier living in a tent was just diggi

      Ayahuasca is DMT, it's a drink that combines DMT containing elements with other elements that allow the DMT to be metabolized in the stomach instead of being destroyed upon ingestion. DMT can also be inhaled by itself, or injected as in the case of this story. DMT is also naturally produced inside your brain.

    The problem with studying drugs like these is that the effects are so profound that there's no way to achieve a proper double blind trial. It looks like they went through the motions but it would be staggeringly obvious to anyone in the room whether DMT or placebo was given.
    • Apparently (if the summary is correct) they could give them LSD as a control group.
    • Sometimes a double blind is redundant when the outcome is so obvious. You don't need a double blind procedure to know if you have injuries after crashing your car for instance. This religious reliance on a method to derive the truth does not apply to all circumstances.

      If you're looking for an effective placebo effect in a drug study, bring in the known control group.

      Teenagers will lie about anything to fit in.

      And besides, if we're looking for profound results of DMT vs. the alternatives, take a look at overdoses and deaths from traditional "solutions" for depression and many other issues plaguing society today. You'll find a rather glaring reason to question why the hell DMT was ever limited by the DEA at Schedule I, preventing any legal Federal funding to study for med

  • Seriously, I have long thought that (some) depression might come for a chemical imbalance, the answer to which is a simple chemical.

    I hope we can quickly find those chemicals.
    • "Chemical imbalance" was the explanation for many years, but modern medicine has fairly decisively proven that that is not the sole cause.
    • Tripping only occurs when somebody uses too much of these drugs. In the tiny doses used for such trials, there is no tripping.

  • Not so long ago there was a lot of hype about ketamine for treating depression. How's that working out?
  • Thatâ(TM)s why they call it âoethe business tripâ

    There are vapes now, too.

  • Are these sources for DMT the equivalent of quoting High Times when debating pro marijuana use? Showing my age!

    Single dose of DMT reduces depression. Unfortunately, also causes insanity.

    • by leptons ( 891340 )
      DMT is naturally produced in your brain. Even though you might think a lot of people are "insane", DMT does not cause "insanity".
  • Is there a full house yet? Pretty much every psychedelic and dissociative seems to have been in the papers as reducing symptoms of major depression - perhaps scientists could talk together a bit rather than working in silos?
  • For the exact same reason DMT can cause a lasting psychosis with a 5 minute half life, it can affect depression. For the same reason as electroshock therapy too.

    Give the brain a big whollop, hope everything settles down in place a bit better, hope you don't break anything ... then pretend you know what you are doing.

Leveraging always beats prototyping.
