Set & Setting
The concept of 'set and setting' is critical in psychedelic research, influencing therapeutic outcomes in clinical environments. Creating optimal conditions is essential for maximising the efficacy and safety of psychedelic-assisted therapies, particularly in the context of mental health disorders.
Key Insights
- 1
Psychedelics can significantly alter emotional processing and cognition, with set and setting playing a vital role in shaping these experiences.
- 2
Clinical trials have shown that psilocybin-assisted therapy can reduce depressive symptoms when conducted in a supportive environment.
- 3
Different musical genres and therapeutic guidance during psychedelic sessions can influence emotional responses and overall therapeutic outcomes.
- 4
Research indicates that both recreational and therapeutic uses of psychedelics are heavily modulated by set and setting, impacting both efficacy and safety.
- 5
Studies suggest that a well-structured therapeutic framework for administering psychedelics can help mitigate the risks of challenging experiences.
What is Set & Setting?
Set and setting refer to the psychological (set) and environmental (setting) contexts in which a psychedelic experience occurs, impacting the individual's responses to the compounds used.
The psychological state includes mood, mindset, and expectations, while the environment encompasses the physical and social surroundings during the psychedelic experience.
Poorly managed set and setting can lead to adverse experiences, making it crucial in clinical settings to ensure a supportive and nurturing environment for patients.
Current Treatments
Standard-of-care treatments for mood disorders, including Major Depressive Disorder (MDD), often involve pharmacotherapy, psychotherapy, or a combination of both. Common medications include SSRIs and cognitive-behavioural therapy (CBT). Recent advances also explore psychedelic-assisted therapies.

Psilocybin and Set & Setting
Psilocybin, a naturally occurring psychedelic compound, has shown significant promise in treating Major Depressive Disorder and other mental health conditions. Its effects are highly influenced by the set and setting; a supportive environment enhances positive therapeutic outcomes, while a poor context can lead to challenging experiences or cognitive distress. Ongoing trials are emphasising the need for well-structured therapeutic settings.
MDMA and Set & Setting
MDMA, known for its empathogenic effects, has been utilised in therapy primarily for PTSD. The efficacy of MDMA-assisted therapy is profoundly strengthened in controlled settings, where the therapeutic alliance and environmental factors contribute positively to the experience. Research highlights how the quality of set and setting significantly reduces adverse psychological effects during sessions.
LSD and Set & Setting
LSD has been studied for its potential in various mental health applications, including anxiety and depression. Its effects can vary widely based on the individual’s mental state and the setting in which it is administered. When provided in a carefully curated therapeutic environment, LSD can facilitate profound insights and emotional breakthroughs.
Clinical Outlook
The future of psychedelic treatment appears promising, particularly with increasing recognition of the importance of set and setting. As more clinical trials validate the efficacy of compounds like psilocybin and MDMA in controlled environments, we may see widespread acceptance and integration of these modalities into mainstream mental health care.
Industrial Landscape
Key industry players such as MAPS, Multidisciplinary Association for Psychedelic Studies, and various academic institutions are heavily involved in research. Non-profits and advocacy groups are also working to promote policy changes and access to psychedelic-assisted therapies.

Resilient Pharmaceuticals
Resilient Pharmaceuticals (formerly Lykos Therapeutics, formerly MAPS PBC) is a US-based public benefit corporation developing MDMA-assisted therapy for PTSD. It was founded in 2014 by MAPS (Multidisciplinary Association for Psychedelic Studies) as a commercial spinout to carry MAPS’ three decades of MDMA research through late-stage trials and regulatory approval. After completing two Phase 3 trials and filing an NDA in 2024, the FDA issued a Complete Response Letter (CRL) in August 2024, citing concerns about functional unblinding, durability of response, safety reporting at two trial sites, and the challenge of blinding psychedelic studies. The CRL requested a third Phase 3 trial. Following the rejection, the company laid off approximately 75% of staff. In May 2025, billionaire investors Antonio Gracias (Gracias Foundation) and Sir Christopher Hohn (TCI Fund) led a $50 million Series B recapitalisation, installing new leadership: CEO Mike Burke and CMO Javier Muniz. Rick Doblin, MAPS’ founder, remains supportive of the new direction. The company rebranded from Lykos Therapeutics to Resilient Pharmaceuticals on 28 August 2025, and continues to negotiate a path to FDA approval for MDMA-assisted therapy for PTSD.

University of Amsterdam
The University of Amsterdam (UvA) is one of the Netherlands' leading research universities, with its Amsterdam UMC Department of Psychiatry conducting clinical trials on psilocybin and psychedelic-assisted therapies for treatment-resistant mental health conditions.
University of California Davis
The Institute for Psychedelics and Neurotherapeutics (IPN) at UC Davis explores the neuroscience of psychedelics. Under the lead of David Olson, the team conducts high-impact interdisciplinary psychedelic science using modern neurobiology and chemistry tools. Contributions by the group include discovering that psychedelics promote neural plasticity, developing a biosensor for measuring hallucinogenic potential, and designing non-hallucinogenic psychedelic analogues with therapeutic potential.
University of Basel
The University of Basel Department of Biomedicine hosts the Liechti Lab research group, headed by Matthias Liechti. Research here is primarily focused on the pharmacology of psychoactive substances. Much of the clinical research exploring the effects of LSD is taking place at University Hospital Basel. Researchers here are exploring the potential of LSD to treat Cluster Headache, Major Depressive Disorder and anxiety associated with severe somatic diseases. Professor Liechti is also conducting studies comparing the acute effects of LSD, psilocybin and mescaline, and MDMA for fear extinction.
Usona Institute
Usona Institute is a US-based 501(c)(3) non-profit medical research organisation (MRO) headquartered in Madison, Wisconsin. Co-founded in 2014 by Bill Linton (CEO of Promega Corporation) and Malynn Utzinger, M.D., Usona was established after Linton witnessed the profound impact of a Johns Hopkins psilocybin study on a terminally ill friend. Unlike commercial drug developers, Usona operates as a mission-driven MRO — conducting and supporting pre-clinical and clinical research on psilocybin and other consciousness-expanding medicines, with the goal of developing accessible, affordable treatments. Its research leadership includes Dr. Charles Raison (Director of Clinical and Translational Research, UW-Madison psychiatrist) and Dr. Alexander Sherwood (medicinal chemist). Usona's psilocybin programme received FDA Breakthrough Therapy Designation for major depressive disorder in 2019. After completing the Phase 2 PSIL201 study (the largest Phase 2 randomised controlled trial of psilocybin for MDD at the time), the Institute launched the Phase 3 uAspire trial in 2024 — a 240-participant, randomised, double-blind, multicentre study comparing 25 mg psilocybin vs placebo in adults with MDD. Usona is also exploring 5-MeO-DMT in early-stage research.
Johns Hopkins University
The Centre for Psychedelic and Consciousness Research focuses on how psychedelics affect behavior, cognition, brain function, and biological health markers. They have been at the forefront of demonstrating the safety and efficacy of psychedelics for mental disorders, expanding their focus into psilocybin research across multiple mental health conditions, including smoking cessation, major depressive disorder, and cancer-related anxiety.

Research with psychedelics is also underway at Yale School of Medicine. A recent study at the university found that a single dose of psilocybin can cause structural changes in the brain that counteract symptoms of depression.
