DMT for Suicidality

6 papers and 1 clinical trial exploring dmt as a treatment for suicidality.

CompoundTryptamine

DMT

A powerful, short-acting tryptamine psychedelic found in many botanical sources, known for rapid onset and intense subjective experiences.

Full DMT profile
Indication700,000 deaths annually worldwide.

Suicidality

Suicidality encompasses a spectrum of suicidal thoughts and behaviours, significantly impacting individuals globally. Recent research into psychedelics, particularly ketamine and ayahuasca, shows promise in rapidly alleviating suicidal ideation associated with mental health disorders.

Efficacy and Safety of the Neuroplastogen TSND-201 for the Treatment of PTSD A Randomized Clinical Trial

In a multicentre, double‑blind, placebo‑controlled phase 2 trial of 65 adults with chronic PTSD, once‑weekly oral TSND‑201 produced significantly greater reductions in clinician‑rated PTSD severity (CAPS‑5; LS mean difference 9.64, P = .01) and improvements in self‑reported symptoms, functioning and depression versus placebo. TSND‑201 was generally well tolerated — common adverse events included headache, decreased appetite, nausea, dizziness and transient blood‑pressure increases — supporting its potential as a rapid‑acting, durable treatment for PTSD.

Health-related behavioral changes following the use of psychedelics in naturalistic settings

This cross-sectional study (n=2,510) of US adults with psychedelic experience found that participants retrospectively reported widespread improvements in health behaviours including reduced alcohol (66%) and tobacco (49%) use, better dietary habits (49%), and decreased impulsivity (48-72%), with microdosers and frequent users showing greater positive changes.

Safety, Pharmacokinetics, and Pharmacodynamics of a 6-h N,N-Dimethyltryptamine (DMT) Infusion in Healthy Volunteers: A Randomized, Double-Blind, Placebo-Controlled Trial

This randomized, double‑blind, placebo‑controlled study found that a 30‑s bolus followed by a 6‑hour intravenous DMT infusion (maximal exposures ≈35 ng/mL) was well tolerated in healthy volunteers with no serious adverse events and only mild, rapidly occurring psychedelic effects. Moderate interindividual pharmacokinetic variability was observed and the highest dose produced transient reductions in sustained attention, postural stability and occipital alpha power, providing a safety and PK/PD basis for future proof‑of‑mechanism studies in patient populations.

Rapid and sustained antidepressant effects of vaporized N,N-dimethyltryptamine: a phase 2a clinical trial in treatment-resistant depression

This open-label fixed-order dose-escalation trial (n=14) evaluated inhaled DMT (15mg & 60mg) for treatment-resistant depression (TRD) for the first time. Results showed rapid and sustained antidepressant effects with a 21-point reduction on the Montgomery-Asberg Depression Rating Scale by day 7 (p<0.001), an 86% response rate, and a 57% remission rate lasting up to 3 months, with significant decreases in suicidal ideation (SI).

Adverse Events in Studies of Classic Psychedelics: A Systematic Review and Meta-Analysis

This systematic review and meta‑analysis of 214 studies (3,504 participants with analysable adverse‑event data) found that high‑dose classic psychedelics were generally well tolerated in clinical/research settings, with serious adverse events occurring mainly in ~4% of participants who had preexisting neuropsychiatric disorders and no reports in contemporary trials of suicide, persistent psychotic disorder or hallucinogen‑persisting perception disorder. Common non‑serious adverse events (headache, anxiety, nausea, fatigue, dizziness) had similar prevalences for psilocybin and LSD, but substantial heterogeneity and limited systematic adverse‑event monitoring across studies highlight the need for improved pharmacovigilance.

Ayahuasca in the treatment of bipolar disorder with psychotic features-A retrospective case study

This retrospective case study describes a woman with bipolar disorder and psychotic features whose suicidality, dissociation and social isolation markedly improved and were sustained after multiple ayahuasca ceremonies, with corroboration of childhood abuse and ongoing symptom reduction over several years. The report suggests potential therapeutic benefits of ayahuasca for severe traumatisation and bipolar symptoms and situates the case within a brief review of low‑dose ayahuasca and LSD treatment literature.

Inhaled DMT for Major Depressive Disorder

This Phase IIb, randomised, double-blind, active-controlled trial (n=140) will evaluate the efficacy and safety of inhaled DMT in adults with major depressive disorder (MDD). It will assess whether a higher-dose inhaled DMT regimen can more rapidly reduce depressive symptoms and suicide risk than a lower-dose active comparator, with primary outcomes focused on change in Montgomery-Åsberg Depression Rating Scale (MADRS) score and incidence of suicidal ideation and behaviour. Participants will be allocated 1:1 to receive either 15 mg followed 1 hour later by 60 mg of inhaled DMT, or 1 mg followed 1 hour later by 4 mg, administered via a Volcano Medic 2 vaporiser in two inhalations. Those who do not achieve remission at Day 7 (MADRS >10) will enter an open-label extension and receive a high-dose session on Day 14 (±3 days), while remitters will not be re-dosed; all participants will then be followed for up to 12 months to examine durability of response, safety, functioning and quality of life.
