How to set up a psychedelic study: Unique considerations for research involving human participants.

Neuroscience and Biobehavioral Reviews July 1, 2026 Marcus J. Glennon, Catherine Bird, Prateek Yadav et al. 2 citations

Setting up a psychedelic study can be a long, arduous, and Kafkaesque process. Researchers are faced with a host of challenges in this rapidly evolving field, necessitating a range of considerations that remain largely unstandardised. Many of the complexities inherent to psychedelic research also challenge existing assumptions around, for example, approaches to psychiatric prescribing, the...

Understanding Neuroplasticity Induced by Tryptamines (UNITy): Understanding Neuroplasticity Induced by Tryptamines: Rewiring Maladaptive Memories in Hazardous Drinking with Memory Reactivation and Dimethyltryptamine (DMT)

Open Science Framework October 20, 2025 Natalia Fernandez‐Vinson, Roger Atkins, Marcus J. Glennon et al.

This study examines the existence and mechanistic underpinnings of lasting neural, cognitive, and behavioural plasticity in response to N-N-dimethyltryptamine (DMT) in a hazardous drinking population. It combines behavioural, neuroimaging, ecological momentary and qualitative data to gain a holistic understanding of potential mechanisms of therapeutic change following DMT. Primarily, we test...

How to set up a psychedelic study: Unique considerations for research involving human participants

arXiv Preprint Archive March 28, 2025 Marcus J. Glennon, Catherine Bird, Prateek Yadav et al.

Setting up a psychedelic study can be a long, arduous, and kafkaesque process. This rapidly-developing field poses several unique challenges for researchers, necessitating a range of considerations that have not yet been standardised. Many of the complexities inherent to psychedelic research also challenge existing assumptions around, for example, approaches to psychiatric prescribing, the...

Impact of psychedelics on craving in addiction: A systematic review.

Journal of psychopharmacology (Oxford, England) February 1, 2025 Sophie-Athéna Chapron, Guilhem Bonazzi, Laura Di Lodovico et al. 5 citations

In the context of the need to increase treatment options for substance use disorders, recent research has evaluated the therapeutic potential of psychedelics. However, there is an incomplete understanding of psychedelics' effects on craving, a core symptom of addictive disorders and a predictor of substance use and relapse. To determine if the use of psychedelics is associated with changes in...

Rewarding Subjective Effects of the NMDAR Antagonist Nitrous Oxide (Laughing Gas) Are Moderated by Impulsivity and Depressive Symptoms in Healthy Volunteers.

The International Journal of Neuropsychopharmacology July 23, 2021 Sunjeev K. Kamboj, Hannah Zhao, Luzia Troebinger et al.

Nitrous oxide (N2O) is an anesthetic gas with both therapeutic and abuse potential. Because N2O is an NMDA receptor (NMDAR) antagonist, its effects are expected to resemble those of the prototypical NMDAR antagonist, ketamine. In this study, we examined the subjective rewarding effects of N2O using measures previously employed in studies of ketamine. We also tested for moderation of these...

The Subjective Response to Nitrous Oxide is a Potential Pharmaco-Endophenotype for Alcohol Use Disorder: A Preliminary Study with Heavy Drinkers.

The International Journal of Neuropsychopharmacology April 1, 2017 Katie Walsh, Ravi Das, Sunjeev K. Kamboj

Healthy people with a family history of alcohol problems show a pattern of subjective responses to alcohol that resemble those of affected probands. Studies on ketamine suggest that up-regulation of N-methyl-D-aspartate receptors (NMDARs) underlies these effects, and point to a pharmacologically-responsive endophenotype reflecting enhanced risk for alcohol-use disorders. Subjective stimulant...

Acute and chronic effects of cannabinoids on effort-related decision-making and reward learning: an evaluation of the cannabis ‘amotivational’ hypotheses

Psychopharmacology September 2, 2016 Will Lawn, Tom P. Freeman, Rebecca Pope et al. 177 citations

RATIONALE: Anecdotally, both acute and chronic cannabis use have been associated with apathy, amotivation, and other reward processing deficits. To date, empirical support for these effects is limited, and no previous studies have assessed both acute effects of Δ-9-tetrahydrocannabinol (THC) and cannabidiol (CBD), as well as associations with cannabis dependence. OBJECTIVES: The objectives of...

Nitrous oxide speeds the reduction of distressing intrusive memories in an experimental model of psychological trauma

Psychological Medicine March 3, 2016 Ravi Das, Amanda J. F. Tamman, Viktoriya L. Nikolova et al. 48 citations

BACKGROUND: Post-traumatic stress disorder (PTSD) involves maladaptive long-term memory formation which underlies involuntary intrusive thoughts about the trauma. Preventing the development of such maladaptive memory is a key aim in preventing the development of PTSD. We examined whether the N-methyl d-aspartate receptor (NMDAR) antagonist gas nitrous oxide (N2O) could reduce the frequency of...

Recreational 3,4-methylenedioxy-N-methylamphetamine (MDMA) or ‘ecstasy’ and self-focused compassion: Preliminary steps in the development of a therapeutic psychopharmacology of contemplative practices

Journal of Psychopharmacology May 18, 2015 Sunjeev K. Kamboj, Emma J. Kilford, Stephanie Minchin et al. 43 citations

3,4-methylenedioxy- N-methylamphetamine (MDMA) produces diverse pro-social effects. Cognitive training methods rooted in Eastern contemplative practices also produce these effects through the development of a compassionate mindset. Given this similarity, we propose that one potential mechanism of action of MDMA in psychotherapy is through enhancing effects on intrapersonal attitudes (i.e....
