About this trial
The goal of this observational study is to evaluate the associations between patient-directed medical cannabis use and chemotherapy-induced nausea and vomiting (CINV), as well as other treatment-related symptoms, among patients receiving chemotherapy that is known to cause nausea. The main questions it aims to answer are:
* Is patient-directed medical cannabis use associated with reduced nausea severity during chemotherapy treatment? * Is-patient directed medical cannabis use associated with improved CINV control? * Is patient directed medical cannabis use associated with improved appetite during chemotherapy treatment? * Is patient-medical cannabis use associated with reduced treatment-related side effects, such as fatigue, sleep disturbances, general pain, and peripheral neuropathic pain?
Researchers will compare participants who report using medical cannabis with participants who do not report using medical cannabis to determine whether differences exist in nausea, CINV outcomes, and other treatment-related symptoms.
Participants will be followed over the course of 3 chemotherapy cycles, and asked to complete questionnaires, nausea diaries, and partake in a blood sample collection. Study participation can last from 6 - 12 weeks, depending on their prescribed chemotherapy cycle frequency.
