Dear Patient,

reports from patients suggest that use of cannabis/marijuana reduces symptoms associated with inflammatory bowel disease (IBD).

We are conducting a study that is assessing the use, the benefits and the side effects of cannabis/marijuana for the self-treatment of inflammatory bowel disease (Crohn’s disease and ulcerative colitis). This questionnaire is directed to all patients with IBD that use cannabis/marijuana for their IBD.

We are asking you to complete the internet based questionnaire. Please make sure that you respond to all questions which may take you approximately 10 minutes.

This research study has been approved by the University of Calgary Conjoint Health Research Ethics Board. You are under no obligation to complete this questionnaire. Your responses to this questionnaire will be kept strictly anonymous.
