MedCan 3 - Medicinal cannabis to relieve symptoms of advanced cancer in palliative care patients

Advanced cancer

This study aims to determine if medicinal cannabis improves symptoms of advanced cancer, such as pain, nausea, shortness of breath, anxiety and depression. The cannabis used in this trial will be CBD dominant, with very small amounts of THC. Participants will not be permitted to drive while on the trial. Half of participants will receive the cannabis product and the other half will receive a placebo. Allocation to either group is random and researchers and patients will be unaware of which group the patient is in.
