Social acceptability of psilocybin-assisted therapy for existential distress at the end of life: A population-based survey

Palliative Medicine January 22, 2024 Louis Plourde, Sue-Ling Chang, Houman Farzin et al. 22 citations

A survey of 2,800 adults in four Canadian provinces found high social acceptability of psilocybin-assisted therapy for existential distress at the end of life. 79.3% considered it a reasonable medical choice, 84.8% agreed public health insurance should cover it, and 63.3% would support legalization for medical purposes. More favorable attitudes were linked to prior psilocybin use, exposure to palliative care, and progressive political orientation. The findings suggest public support is strong enough to help mobilize resources and improve access to this emerging therapy in palliative and end-of-life care.

Roadmap for Equitable Access and Responsible Use of Psilocybin-Assisted Psychotherapy in Palliative Care

Palliative Medicine Reports April 17, 2025 Michel Dorval, Sue-Ling Chang, Houman Farzin et al. 3 citations

A forum in Quebec, Canada, with 57 participants including patients, healthcare professionals, researchers, and policymakers, produced 16 recommendations for expanding access to psilocybin-assisted psychotherapy in palliative care. The recommendations address patient eligibility and equity, regulatory frameworks and respect for autonomy, logistical and organizational aspects, professional education and training, public awareness and information, and research. The report suggests these recommendations could guide similar efforts in other jurisdictions facing barriers to this therapy.

Psychedelic Treatment with Psilocybin: Addressing Medical Malpractice Risk and Physicians’ Concerns

The Journal of Law Medicine & Ethics January 1, 2025 Katherine Cheung, M J Brodie, Sue-Ling Chang et al. 2 citations

Physicians may hesitate to prescribe psilocybin for conditions like end-of-life anxiety and depression due to stigma and potential medical malpractice liability. This paper examines the risk of malpractice claims arising from psilocybin treatment in Canada, using exploratory vignettes to illustrate the relevance and limits of such claims. It argues that the absence of established medical standards, standardized training, and credentialing increases liability risks. More clinical trials, meta-studies, and knowledge sharing are needed to develop training programs and medical standards of practice to better realize psilocybin's potential.

Supporting Meaningful Choices: A Decision Aid for Individuals Facing Existential Distress and Considering Psilocybin-Assisted Therapy

Healthcare September 12, 2025 Ariane Bélanger, Sue-Ling Chang, Jean-François Stephan et al. 1 citation

A decision aid for psilocybin-assisted therapy (PAT) was developed to help patients and healthcare professionals weigh risks and benefits when considering treatment for existential distress in serious illness. The booklet, created with a multidisciplinary steering committee following international standards, covers PAT education, treatment comparisons, and personal reflection. Feedback from five patients and five healthcare professionals guided refinements to improve clarity, balance, and usability. The final version met acceptability and usability criteria, offering balanced information to support shared decision-making in palliative care.

Experiential dimension of psilocybin-assisted therapy training: Necessity or hindrance to wider accessibility?

Journal of Psychedelic Studies January 21, 2025 Louis Plourde, Sue-Ling Chang, Houman Farzin et al. 1 citation

The debate about whether psychotherapists should personally experience non-ordinary states of consciousness during psilocybin-assisted therapy training is important because it influences treatment safety, effectiveness, and accessibility. Ethical and practical concerns about making such experience a training standard need urgent attention where psilocybin therapy is being integrated into healthcare. The authors argue that the most balanced and ethical approach is to legally allow psilocybin use for professional training but not require it.

Bringing Psilocybin-Assisted Therapy to Palliative Oncology: Early Lessons from Real-World Implementation.

Healthcare (Basel, Switzerland) June 3, 2026 Michel Dorval, Virginie Audet-Croteau, Sue-Ling Chang et al.

After one year of offering psilocybin-assisted therapy (PAT) at a Canadian university-affiliated tertiary care center, no patients had received the treatment despite clinicians and managers viewing it favorably. Interviews with ten professionals identified administrative and regulatory procedures, along with logistical constraints, as key barriers, while perceived clinical relevance and institutional leadership were facilitators. The estimated cost of delivering a complete PAT intervention ranged from 2,648 to 5,827 Canadian dollars per patient, excluding the cost of psilocybin itself. The gap between regulatory authorization and actual service uptake highlights the need for structured implementation strategies, sustained institutional support, and alignment between regulatory frameworks and clinical workflows.
