N,N-DMT and 5-MeO-DMT are extremely potent and short-acting entheogens found naturally in the plant and animal kingdoms. For thousands of years, N,N-DMT has been an essential ingredient in ayahuasca, an Amazonian brew administered by shamans made of plant-sourced DMT and MAOIs. On the other hand, 5-MeO-DMT is a chemical relative of DMT found in the South American psychedelic snuff called yopo and produced in the venomous secretions of the Colorado River toad.

Besides a profound spiritual reorientation, the transformational experiences occasioned by these compounds have the capacity to deeply heal disorders of the mind and body and connect us with realms unimaginable to everyday consciousness. This article is intended to be a comprehensive DMT resource for those seeking more information in the form of articles, studies, books, documentaries, and videos. In addition, we will explore some recommended DMT retreats, and why and how to find integration therapists after the experience.

Clinical Trials and Studies

For millennia, indigenous shamans in the Amazon basin have successfully used ayahuasca for deeply healing spiritual, emotional, and physical issues. In the West, the exploding interest in psychedelic research has led multiple research groups and partnering institutions to validate and quantify this ancient knowledge with controlled settings and dosages for mental health disorders such as depression and addiction. 

Imperial College London (ICL)

Home to the Centre for Psychedelic Research headed by psychedelic researcher Dr Robin Carhart-Harris, Imperial College London has been at the forefront of modern psychedelic research. The center’s clinical research focuses on the therapeutic potential of psychedelics like DMT and psilocybin for major depression.

ICL Depression Trial (Active)

  • ICL Depression Study: In collaboration with the neuropharmaceutical company Small Pharma, Imperial College London researchers are conducting the world’s first clinical trial for DMT this year. The first phase of the trial is planned to start this month, with the initial aim of evaluating the effects of DMT-assisted therapy in healthy volunteers. The subsequent Phase IIa trial will evaluate the efficacy of the treatment in patients with Major Depressive Disorder (MDD).

University Hospital of Basel

University Hospital of Basel in Basel, Switzerland, is home to the Liechti lab, a leading psychedelic research group that investigates the effects and pharmacological action of LSD and other psychedelics.

University Hospital of Basel Clinical Trial (Active)

  • Effects of Dimethyltryptamine in Healthy Subjects (DMT): Researchers in the Liechti Lab at University Hospital of Basel are collaborating with the psychedelic biotech company MindMed to evaluate the effects of different DMT dosing regimens in 30 healthy participants. This Phase I clinical trial was announced in June of 2020 and expected to begin in the fourth quarter of 2020. 

University of Victoria

Research from 2013 led by Dr. Gerald Thomas at the University of Victoria, Canada, investigated how ayahuasca therapy can lead to long-term improvements in addiction outcomes. This research has set the stage for further research to investigate ayahuasca-assisted therapy for addiction treatment, and to confirm their promising findings.

University of New Mexico (UNM)

From 1990 to 1995, Dr. Rick Strassman conducted groundbreaking clinical research on DMT at the University of New Mexico. After a decades-long hiatus from psychedelic research nationwide, Dr. Strassman revived these studies by intravenously administering 400 doses of N,N-DMT to 60 volunteers and documenting the experiences and therapeutic potential of the sessions. The results from these studies cumulated into a book entitled DMT: The Spirit Molecule. 

UNM Studies

The following studies led by Rick Strassman examined the dose-response characteristics, tolerance effects, and pharmacological action of DMT during his five years conducting human research with DMT: 

Johns Hopkins University (JHU)

Established in 2019, JHU’s Center for Psychedelic and Consciousness Research is dedicated to understanding how psychedelics affect behavior, mood, cognition, brain function, and outcomes for disorders like depression, PTSD, and substance use disorder. 

JHU Studies on 5-MeO-DMT

5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) used in a naturalistic group setting is associated with unintended improvements in depression and anxiety: This naturalistic observation study found that up to 80% of the 362 survey respondents reported significant improvements in depression and anxiety following the use of 5-MeO-DMT. The biggest improvements in depression and anxiety were most correlated with experiences rated as intensely mystical, spiritual, and meaningful. This study was completed under the direction of Dr. Roland Griffiths, a psilocybin research pioneer and Founding Director of the Center for Psychedelic and Consciousness Research at Johns Hopkins University.


The following recommended books on N,N-DMT, ayahuasca, and 5-MeO-DMT explore the science and history of these medicines, personal accounts and interpretations of the experiences, and their therapeutic potential.

Retreats and Integration Therapists

Ayahuasca and 5-MeO-DMT retreats have become increasingly popular in recent years as knowledge has spread around the world about the deep healing potential offered by these medicines. Accordingly, a wide variety of DMT retreats have come into being to meet the demand, each of which may differ in its pre-screening requirements, accommodations, services, and ceremonies. 

As Western modalities have melded with Indigenous knowledge, many retreat centers successfully synthesize psychotherapeutic modalities with Indigenous approaches to the plant medicine. This has created an ideal environment for treating addiction, PTSD, and other disorders of the mind and spirit.


Below are some of the most recommended DMT retreat centers. For a fuller listing and more information, consult this forum thread at and for attendee reviews.

Integration Therapists

The intensity and profundity of DMT experiences ventures about as far as the human consciousness can go from the ordinary experience of consensus reality and the self. While some people may find the DMT experience seamlessly integrates into their day-to-day lives, others experience post-trip challenges such as restlessness, difficulty sleeping, trip reactivations, and more. Integration therapists can help one stay grounded after the experience and unpack what was revealed for maximal clarity, insight, and meaning. Explore these resources for post-DMT integration help:

  • MAPS Psychedelic Integration List—A comprehensive list of international and US-based psychedelic integration therapists.
  • Psychedelic Support Network—A list curated by Psychedelic Support of credentialed integration therapists offering services, such as pre- and post-ritual counseling and individual and group psychedelic integration.
