Considerations and cautions for the integration of psilocybin into routine clinical care: a consensus statement from the US National Network of Depression Centers' Task Group on Psychedelics and Related Compounds.

The potential for psilocybin, and other psychedelic drugs, to fulfil a much needed and potentially transformative class of psychiatric treatments has garnered significant attention. Consequently, there has been a great deal of interest and investment in accelerating its development and potential implementation in routine clinical practice. However, the expanding scope of scientific discovery, heightened media coverage, and commercial interests in the field risk outpacing the rate of developments in the necessary guidelines and infrastructure required for integration of psilocybin into clinical practice. The US National Network of Depression Centers (NNDC) Task Group on Psychedelics and Related Compounds-comprising psychiatrists, psychologists, neuroscientists, psychedelic researchers, and leaders in healthcare consulting affiliated with the NNDC-developed this consensus statement as a summary of clinical expertise and opinion on the matter, to recognise psilocybin's therapeutic potential while also emphasising the need for further research and careful consideration before the integration of psilocybin into routine clinical care. We outline the current state of the science on psilocybin, incorporating articles published through April 2025. We identify key areas for further research and frame them within the context of therapeutic and ethical implications surrounding psilocybin's use in future clinical practice. We highlight the need for further research to address gaps in understanding of therapeutic dosage, efficacy across diverse populations, and long-term safety. Finally, we propose an agenda which calls for diversification of funding, collaborative research efforts, standardised training for healthcare providers, and careful consideration of ethical dilemmas inherent in the theorised clinical use of psilocybin. Crucially, we advocate for a balanced approach that prioritises rigorous scientific standards while considering the urgency of the need for better treatment options, ensuring equitable access and safety as the field progresses. We acknowledge that the single-country focus of the NNDC may limit the generalisability of recommendations to international contexts with differing healthcare systems and regulatory landscapes.
