Randomized phase 2b study or cannabidiol oil versus placebo for relief of symptoms in advanced cancer

The use of cannabis for therapeutic benefit has risen over the past few years with strong public belief in its benefit, despite very limited evidence. The randomized phase 2b MedCan1-CBD study in Brisbane (Australia) compared cannabidiol (CBD) oil versus placebo for the relief of symptoms in patients receiving palliative care for advanced cancer. CBD oil did not add value to the reduction in symptom distress provided by palliative care alone.
