The investigators are conducting a pilot (i.e. a small study) in order to find out the
effectiveness and safety of medical cannabis in the management of chronic pain. At the end of
this 3 month study, investigators will gather information on how easy it is for patients to
enroll and complete the entire study. The results of this pilot study will then be used to
determine if the weaning protocol is useful and help the study team design a larger
randomized controlled trial.
