The effects and side effects of medical cannabis are not well-established. In 2018, cannabis was approved as a medical drug in Denmark - giving all doctors the opportunity to subscribe medical cannabis to their patients. In this case report a 64-year-old kidney-transplanted woman started cannabis droplets due to chronic back pain, which resulted in increased appetite, weight gain and development of diabetes mellitus.
