@djchambers, I'm tagging fellow members like @franciekid @lisag03 @jmb73 @cjay who shared their use of cannabis to help with the side effects of cancer treatment in this related discussion:
- Has anyone tried cannabis to help with chemo nausea? https://connect.mayoclinic.org/discussion/cannabis

They can offer more of their experiences.

Many cancer centers offer guidance on the proper use of medical cannabis to help with cancer symptoms as part of their integrative medicine programs. Mayo Clinic is running a study on its use at the moment:
- Assessing Benefits And Harms Of Cannabis/Cannabinoid Use Among Cancer Patients Treated In Community Oncology Clinics https://www.mayo.edu/research/clinical-trials/cls-20589454

@djchambers, you were wise to discuss with your oncologist since cannabis is contraindicated with some treatments, like immunotherapy.
