Background: The use of medical cannabis represents an opportunity to improve access to equitable cancer treatment among minoritized populations who frequently face barriers to traditional palliative care options or mental health treatments. Poor mental health among cancer survivors is of concern as it reduces adherence to cancer survivorship treatment and can reduce overall survival. The COVID-19 pandemic has highlighted the importance of access to palliative care due to the increase of mental health symptoms among cancer survivors. Despite the potential benefits of medicinal cannabis, data describing the use of cannabis to manage mental health symptoms among cancer survivors is limited, particularly in the context of the COVID-19 pandemic. Objective: Our objective was to examine the prevalence of mental health symptoms and the behavioral impacts of the COVID-19 pandemic on cancer survivors who endorse cannabis use. Methods: Our participants included adults (≥18 years) who self-reported medicinal cannabis use and responded to our internet-based questionnaire (03/21/2020-03/24/2021). Overall, we received 3,594 responses. For this study, data included 158 participants including 79 cancer survivors (2.2%) along with age-matched medicinal cannabis users without a history of cancer (N = 79). Descriptive statistics were used to compare demographic characteristics, prevalence of generalized anxiety (GAD-7), and depression (CES-D-10), changes in behavior during the COVID-19 pandemic, and self-reported coping mechanisms by cancer survivorship status. Results: Overall, 61% and 48% of cancer survivors self-reported to use medicinal cannabis to manage their anxiety and depression, respectively. Additionally, 54% of cancer survivors reported cannabis use to manage their chronic pain. Probable clinical depression (CES-D-10 score ≥ 10) and anxiety (GAD-7 score ≥ 10) were identified in 50.7% and 38.9% of cancer survivors, respectively. Cancer survivors were more likely to report that their anxiety symptoms made it very or extremely difficult to work, take care of things at home, or get along with other people (23.0% vs. 11.8%, p = 0.015) than adults without a history of cancer. Pandemic-related coping mechanisms frequently reported by cancer survivors with anxiety or depression included more sleep (47.5%), practicing meditation/mindfulness (47.5%), physical activity (47.5%), talking to family and friends (42.5%), overeating or stress-eating (25.0%), and using more cannabis (25.0%). Cancer survivors with anxiety and depression reported to be more likely to fear giving COVID-19 to someone else (47.5% vs. 23.1%, p=0.023) and to fear being diagnosed with COVID-19 (77.5% vs. 38.5%, p&lt;0.001) compared to cancer survivors without mental health conditions. Conclusion: Given the prevalence of anxiety and depression symptoms reported among cancer survivors and their use of cannabis, further research is recommended to evaluate its use as palliative care to improve mental health and quality of life among cancer survivors.
