Fibromyalgia is serious chronic pain condition which is often accompanied by sleep
disturbances, fatigue and disability and reduced quality of life. There is no cure and
treatments are based on reliving symptoms and maintaining function. The currently available
medical treatments are not helping many patients, and many get side-effects. Medical cannabis
is sought after among patients and many use this medication un-licenced, although it is not
properly documented if it works or is safe. Therefore, it is necessary to investigate the
effects and safety of medical cannabis in a properly designed randomized trial. The aim of
the study is to investigate if cannabidiol (CBD) can improve pain, sleep, function and
quality of life in patients with fibromyalgia. The study will include 200 patients, who will
receive either cannabidiol or placebo over a period of 24 weeks. Participants will be closely
looked after for improvements in their condition and for potential side-effects to ensure
safety.
