BACKGROUND: -dimethyltryptamine (DMT); however, long-term effects, including broader well-being dimensions, are sparsely explored across populations. AIMS: Investigating whether DMT produces sustained improvements in anxiety, life satisfaction, and quality of life, in both healthy individuals and patients with treatment-resistant depression (TRD). METHODS: In 2 open-label clinical trials, 27...
Abstract Paradoxically, psychedelics have long been used as models of both psychosis and therapy. After proposing mystical experiences as a link between these models for lysergic acid diethylamide (LSD), we aimed to extend and refine this framework for N,N -Dimethyltryptamine (DMT). In a randomised, placebo-controlled, double-blind, crossover study, 25 healthy participants received DMT (60mg)...
Vaporized N,N-Dimethyltryptamine (DMT) has a short duration and simple application, prompting this technique as a new approach for psychedelics' clinical use. Building on our initial dose-ascending studies and addressing potential confounding effects of dosing order, this study is the first to evaluate inhaled DMT in a randomized, placebo-controlled, double-blind design. Given DMT's therapeutic...
Depression affects over 185 million people worldwide, with approximately one-third classified as treatment-resistant depression (TRD). Current treatments, such as oral antidepressants, often take around 3 weeks to become effective, with no immediate anti-suicidal benefits. The field urgently needs innovative therapies that provide rapid relief. Psychedelics like psilocybin and ayahuasca have...
N,N-Dimethyltryptamine (DMT), a naturally occurring psychedelic tryptamine contained in the indigenous ayahuasca brew, has shown antidepressant effects. This open-label clinical trial investigates for the first time the efficacy of vaporized DMT in treatment-resistant depression (TRD). Six TRD patients participated in an open-label, fixed-order, dose-escalation study, receiving a lower (15 mg)...
Psychedelic experiences, especially those induced by substances such as N,N-Dimethyltryptamine (DMT), are often characterized by high subjective intensity, complex visual content, and notable ineffability-that is, the difficulty of being fully expressed in words. This expressive limitation poses a significant challenge to the integration of the experience, which is essential for the therapeutic...
Psychedelics are being increasingly examined for their therapeutic potential in mood disorders. While the acute effects of ayahuasca, psilocybin, and lysergic acid diethylamide (LSD) last over several hours, inhaled N,N-Dimethyltryptamine (DMT) effects last around 10 min, which might provide a cost- and time-effective alternative to the clinical application of oral psychedelics. We aimed at...
Abstract Introduction N,N-Dimethyltryptamine (DMT), a naturally occurring psychedelic tryptamine contained in the indigenous ayahuasca brew has shown antidepressant effects. This Phase 2a clinical trial investigates for the first time the efficacy of isolated DMT in treatment-resistant depression (TRD). Methods Six TRD patients participated in an open-label, fixed-order, dose-escalation study,...
