The Serotonin 2B (5‐ HT2B ) Receptor: A Narrative Review of Preclinical and Clinical Evidence on the Safety Considerations and Therapeutic Potential for the Treatment of Depression

Clinical Pharmacology & Therapeutics May 28, 2026 Gia Han Le, Sabrina Wong, Danica E. Johnson et al.

Major depressive disorder (MDD) and treatment-resistant depression (TRD) remain leading causes of disability, providing the impetus for receptor-level treatment strategies beyond monoamine reuptake. The serotonin 5-HT2B receptor (5-HT2BR) is uniquely positioned at the interface of central-antidepressant mechanisms and peripheral cardiac risks. Herein, we reviewed preclinical, translational and...

Psychedelic Use and Missed Needed Mental Health Treatment: Gender Differences in Unmet Perceived Need for Care

Psychoactives May 12, 2026 Sean M. Viña

While prior research links psychedelic use to improved psychological outcomes, less is known about whether psychedelic exposure relates to engagement with formal mental health care when treatment is recognized as needed. Using publicly available, de-identified pooled data from the National Survey on Drug Use and Health (2008–2019), this study examines whether lifetime psychedelic use is...

Fusing Specialized Surveys of Rare Populations to Larger Surveys for Generalized Inference: Cross-Sectional Survey Study.

Journal of Medical Internet Research April 27, 2026 Karilynn M Rockhill, Elizabeth A Bemis, Nicole Schow et al. 2 citations

Mainstays of pharmacoepidemiology are large, representative, behavioral surveys, which focus on many drugs with few detailed behaviors. Smaller, targeted studies measure drug-specific patterns but without explicit generalizability assumptions; the evidence generated is narrow. In this cross-sectional survey study, we outline an estimation framework based on data fusion and combine two surveys:...

Substance use predictors of arrest and self-reported criminal behavior in the United States: The role of psychedelics and rarely used drugs

Journal of Psychopharmacology April 16, 2026 Jesse J. Norris 1 citation

Background: Little research investigates the role of rarely used drugs in criminal offending. Moreover, given research suggesting that psychedelics reduce criminal offending, more research is needed to further document connections between psychedelics and crime. Aim: This study examines the role of rarely used drugs in criminal behavior and extends previous research on psychedelics by...

New psychoactive substances (designer drugs): an approach to classification

Neurology Bulletin March 23, 2026 Azat R. Asadullin, Elvina A. Akhmetova, Ilia S. Efremov et al.

BACKGROUND: Substance use disorders remain a global public health problem. In recent decades, the drug market has undergone substantial changes, with traditional drugs increasingly replaced by new psychoactive substances characterized by high toxicity and strong addictive potential. Their distribution via the Internet and social media impedes control and increases risks to public health. AIM:...

The renaissance of research on psychedelics in child and adolescent psychopharmacology

Child and Adolescent Psychiatry and Mental Health March 13, 2026 Marc-Antoine Crocq, Philippe Auby

Aims The recent regulatory approval of esketamine in adults heralded the renaissance of research into psychedelic compounds. However, the relevance of this resurgence for children and adolescents remains unclear. This review examines the rationale for investigating psychedelics in pediatric psychopharmacology. Methods We reviewed recent literature, regulatory documents, and clinical trial...

Efficacy and risks of psychedelics in treatment of posttraumatic stress disorder: A systematic review

American Journal of Health-System Pharmacy March 4, 2026 Jennifer E. Thomas, Anna Dellarole, Robin J Jacobs

MDMA and ketamine IV currently have the greatest support in the literature for efficacy in PTSD. Studies suggest treatment with these agents under supervision may lead to improvements in PTSD symptoms, with the medications being generally well tolerated. However, caution should be used when interpreting study results due to limitations such as treatment expectancy effect and the potential for...

Psychedelic therapeutics in psychiatric conditions

Neuropsychopharmacology January 16, 2026 Philip D. Harvey, Charles B. Nemeroff 2 citations

Interest in psychedelic therapies is booming, with hundreds of studies in process. Despite the interest, there are no approved psychedelic treatments for any psychiatric condition. Further, the one large-scale development program using MDMA that reached the FDA was disapproved by the agency for reasons that could apply to clinical trials for classical psychedelics. We review the definitions of...
