How cannabis affects quality of life in newly diagnosed blood cancer patients

This study is asking newly diagnosed multiple myeloma patients to share information about their health, symptoms, and quality of life over time. Researchers want to understand whether cannabis use — if patients choose to use it — affects how patients feel, what side effects they experience, and how well they're doing overall. This is an observational study, meaning researchers are watching and collecting information rather than testing a new drug.

Multiple myeloma patients often struggle with pain, fatigue, nausea, and other difficult symptoms while undergoing treatment. Some patients use cannabis to help manage these symptoms, but doctors don't have clear information about whether it actually helps or causes problems. This study aims to fill that gap by carefully tracking what happens to patients who do and don't use cannabis.
