This study investigated individuals across Canada who have at one point been diagnosed with cancer, and have ever tried using cannabis to help improve their sleep. Insomnia symptoms are reported by up to 87% of cancer patients, making it one of the most common side effects of cancer treatments. Many cancer survivors use cannabis as a treatment for cancer-related symptoms, including poor sleep. The effects of cannabis on sleep depend on many factors such as the formula, dosage, and method of ingestion. There has been little research on the motives of Canadian cancer survivors who use cannabis. We conducted this study to better understand the reasons why and how they use cannabis products as a sleep aid to inform research that will better address their sleep problems.
