With nearly 25% of surveyed cancer patients reporting [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/), this data helps clinicians understand patient preferences and perceived benefits outside of controlled trial settings. Clinical Summary This cross-sectional survey of 2,602 cancer patients in Northern California found that 643 (24.7%) reported cannabis use, with higher odds among younger patients, those with Stage 4 disease, and patients receiving chemotherapy. The study documented patient-reported symptom improvements and spending patterns, providing demographic and usage pattern data from a large, diverse oncology population over a six-year period. While the observational design limits causal inference, the large sample size and real-world setting offer valuable insights into actual patient behaviors and perceived benefits. Dr. Caplan’s Take “This confirms what I see clinically – cancer patients are using cannabis whether we discuss it or not, particularly those with advanced disease and active treatment. The 25% usage rate likely underestimates actual use given social desirability bias in surveys.” Clinical Perspective 🧠 Oncologists should proactively discuss cannabis use with patients, especially those with advanced disease or receiving chemotherapy, as a quarter are likely already using it. This data supports the need for evidence-based guidance on dosing, drug interactions, and product selection rather than avoiding the conversation entirely. 💬 Join the Conversation Have a question about how this applies to your situation?

This study found that 24.7% of cancer patients surveyed reported using cannabis. Patients most likely to use cannabis were younger in age, had advanced stage 4 cancer (3.28 times more likely), and were receiving concurrent chemotherapy treatment (2.45 times more likely). #### What are the main reasons cancer patients use cannabis? Cancer patients primarily use cannabis for symptom management related to their disease and treatment. The most common reasons include managing appetite loss, nausea, sleep disturbances, and pain associated with cancer or [chemotherapy side effects](https://cedclinic.com/medical-cannabis-safety-efficacy-cancer-study/). #### Should I discuss cannabis use with my oncologist? Yes, you should always discuss cannabis use with your oncology team. Given that patients receiving chemotherapy are significantly more likely to use cannabis, open communication ensures safe integration with your current treatment plan and helps monitor for potential drug interactions. #### Is cannabis use more common in patients with advanced cancer? Yes, this study demonstrates that patients with stage 4 (advanced) cancer are over three times more likely to use cannabis compared to those with earlier-stage disease. This likely reflects the increased symptom burden and treatment intensity associated with advanced cancer stages. #### How reliable is the evidence on cannabis benefits for cancer patients? This study provides real-world evidence from patient-reported experiences rather than controlled [clinical trials](https://cedclinic.com/endocannabinoid-system-emotional-memory-ptsd-treatment/). While patients reported perceived benefits for various symptoms, more rigorous [clinical research](https://cedclinic.com/cannabis-based-therapies-smoking-cessation/) is needed to establish definitive therapeutic efficacy and optimal dosing guidelines for cancer-related symptoms. {“@context”: “https://schema.org”, “@type”: “ScholarlyArticle”, “headline”: “Demographics, methods of use, and perceived benefits among patients with cancer who use cannabis.”, “url”: “https://pubmed.ncbi.nlm.nih.gov/41686327/”, “about”: “supportive care cancer official journal multinational”, “isPartOf”: “Supportive care in cancer: official journal of the Multinational Association of Supportive Care in Cancer”} [https://cedclinic.com/contact/](https://cedclinic.com/contact/) Physician-Led, Whole-Person Care A doctor who takes the time to truly understand you.
