As more people with cancer are living longer, the long-term psychological burdens of cancer are increasingly recognized as essential aspects of care. Depression, anxiety, fear of recurrence, and deep existential distress are common among patients with cancer, especially those with advanced or terminal disease. Yet traditional interventions, including antidepressants and talk therapy, often fall short in addressing the full scope of this suffering. In recent years, psychedelic-assisted therapy has gained attention as a potential tool to bridge this gap. Emerging research suggests that psychedelics such as psilocybin and MDMA may offer significant, lasting relief for patients struggling with cancer-related psychological distress.1 Far from a radical idea, psychedelic-assisted therapy is now being seriously considered in academic and clinical settings for its unique ability to target the emotional, spiritual, and existential challenges of serious illness.
To better understand how this evolving field could transform supportive oncology care, and what it will take to bring psychedelic-assisted therapy from promising research to real-world practice, Oncology Issues spoke with Jennifer Bires, MSW, LCSW, OSW-C, FACCC, executive director, Life with Cancer and Patient Experience at Inova Health System in Fairfax, Virginia, to gain her insights and experience at the forefront of this important work.
What Is Psychedelic-Assisted Therapy?
Psychedelic-assisted therapy involves the use of psychedelic compounds, such as psilocybin, MDMA, LSD, or ketamine, that are administered within a structured therapeutic framework. Patients are supported through preparation sessions, monitored dosing experiences, and post-experience integration by trained clinicians. This process is designed not only to manage immediate symptoms but also to help patients process difficult emotions, find meaning, and foster a sense of connection. Unlike conventional antidepressants, which often require weeks to take effect and ongoing use, studies show that even a single psychedelic-assisted therapy session can result in profound improvements lasting 6 months or more.2 Currently, outside of a few states like Oregon and Colorado, which have created legal access to select psychedelic drugs, these drugs—with the exception of ketamine—are only available to patients with cancer through enrollment in a clinical trial.
The Evidence
In a recent narrative review, Bires examined the growing body of evidence supporting psychedelic-assisted therapy for patients with cancer and other serious illnesses.3 Her analysis focused on 5 randomized controlled trials conducted between 2011 and 2020, exploring psilocybin, LSD, and MDMA-assisted therapies. The results were consistently promising:
However, Bires also highlighted several limitations: small sample sizes, limited diversity among participants, and variations in study protocols. The trials predominantly involved white, well-resourced participants, underscoring a need for more inclusive research moving forward.3
How Psychedelic-Assisted Therapy May Help in Oncology
Psychedelic-assisted therapy addresses the emotional toll of cancer by targeting deep psychological, social, and spiritual distress. Its benefits extend beyond symptom management to encompass more holistic healing by:
Despite its promise, integrating psychedelic-assisted therapy into oncology and palliative care presents challenges. The therapy is time- and resource-intensive, with dosing sessions often lasting 6 to 8 hours.3 Clinical infrastructure, patient selection, and therapist training are critical considerations.
Bires emphasizes that psychedelic-assisted therapy is not a “one-size-fits-all” solution but rather an additional tool to address the complex emotional and existential distress associated with cancer. Just as art therapy, mindfulness practices, and conventional medications play unique roles in psychosocial care, psychedelic-assisted therapy offers another avenue for patients to manage the psychological and existential impacts of a cancer diagnosis. “Psychiatric medications weren’t developed with cancer patients in mind,” Bires explains. “They can take a long time to work and often don’t get at the root cause of anxiety or depression. We need new tools.” One of psychedelic-assisted therapy’s most compelling implications is its ability to address the deep existential distress that often accompanies a cancer diagnosis—the questions of meaning, mortality, and legacy that conventional treatments frequently overlook. Patients facing incurable disease often struggle with anxiety about the unknown, fear of death, and a profound sense of impermanence. This therapy helps individuals confront these fears in a supportive, therapeutic setting, fostering acceptance and meaning-making that can improve quality of life even in the face of terminal illness. Bires “hopes this conversation encourages people to think differently about how we support patients at the end of life. It can help provide people greater peace, meaning, and connection.”
Centering Health Equity and Access
A critical concern for Bires is ensuring that psychedelic-assisted therapy does not become an exclusive option available only to the privileged. The current landscape of psychedelic research has been criticized for its lack of diversity.3 Bires advocates for developing culturally competent care models, equitable reimbursement structures, and community education initiatives to broaden access. “Examine your own biases. Educate yourself, so you can talk about these therapies with patients who are interested. Read the research, follow the clinical trials, and start imagining what integration might look like in your setting,” she advises.
Preparing for the Future: Practical Steps for Oncology Teams
With phase 3 trials for psilocybin already completed and FDA approval potentially on the horizon, oncology teams should begin preparing now.2 Steps include:
Organizations like the Multidisciplinary Association for Psychedelic Studies (MAPS), and the Integrative Psychiatry Institute offer educational resources and certification programs.
Innovation Beyond the Patient: Supporting Caregivers and Families
Psychedelic-assisted therapy’s potential should not be limited just to patients. Bires is particularly interested in expanding the reach of this therapy to include caregivers, a population often overlooked in psychosocial oncology research. Recognizing that caregivers carry significant emotional burdens, she is exploring a clinical trial focused on caregivers of patients with stage IV cancer. The goal is to improve both the caregiver’s wellbeing and the quality of support they can provide to the patient. This broader application of psychedelic-assisted therapy has the potential to enhance the entire care ecosystem surrounding the patient. “This isn’t about making grief disappear, it’s about making it less distressing,” Bires clarified. “People who undergo psychedelic-assisted therapy often describe a sense of continued connection with their loved ones after death—a different understanding of mortality that reduces fear and supports healing.”
A Call to Action
For Bires, the future of psychedelic-assisted therapy in oncology requires clinicians to maintain open-mindedness, educate themselves, and evaluate readiness. She urges the oncology community to engage with this evolving field not as a fringe movement, but as a legitimate medical approach with the potential to alleviate suffering in ways previously inaccessible. Clinicians interested in becoming early adopters can start by reviewing current literature on psychedelic-assisted therapy in cancer care, following clinical trials at ClinicalTrials.gov, or reaching out to research teams in their region. Formal training programs are also available through organizations offering certification in psychedelic-assisted psychotherapy. While each state’s legal status differs, engagement in research and preparation is legal and urgently needed.
Ultimately, Bires sees psychedelic-assisted therapy as part of a broader toolkit to support cancer patients’ emotional and spiritual wellbeing. “We pathologize mental health so often, but these are normal reactions to terrible circumstances,” she says. “For the right patients, psychedelic-assisted therapy can be one of the most meaningful tools we have.”
As health care continues to evolve toward more holistic, patient-centered models, psychedelic-assisted therapy may soon find its place as a standard, evidence-based component of supportive cancer care.
