A Survey of Cannabis Use among Patients with Inflammatory Bowel Disease (IBD).

Inflammatory bowel diseases (IBDs) are chronic conditions of unknown cause or cure. Treatment seeks to reduce symptoms and induce and maintain remission. Many patients have turned to alternatives, such as cannabis, to alleviate living with IBD. This study reports the demographics, prevalence, and perception on cannabis use of patients attending an IBD clinic. Patients agreed to participate and completed an anonymous survey during their visit or online. Descriptive analysis, Fisher's exact test, and Wilcoxon-Mann-Whitney rank-sum test were used. One hundred and sixty-two adults (85 males, 77 with CD) completed the survey. Sixty (37%) reported use of cannabis, of which 38 (63%) used it to relieve their IBD. A value of 77% reported low to moderate knowledge about cannabis, and 15% reported little to no knowledge. Among cannabis users, 48% had discussed use with their physician, but 88% said they would feel comfortable discussing medical cannabis for IBD. Most saw improvement of their symptoms (85.7%). A considerable number of patients with IBD use medical cannabis for their disease, unknown to their physician. The study reinforces the importance that physicians understand the role of cannabis in the treatment of IBD in order to appropriately counsel patients.

Knowledge, Perception, and Use of Cannabis Therapy in Patients with Inflammatory Bowel Disease.

OBJECTIVE: In 2017, the government of Puerto Rico legalized medical cannabis for several conditions including Crohn's disease (CD). There is little information about cannabis use in this population. This study aimed to develop a demographic characterization and evaluate patient perception on cannabis use for Inflammatory Bowel Disease (IBD) at the University of Puerto Rico Center for Inflammatory Bowel Diseases. METHODS: One hundred patients of ages 21 or older with a confirmed diagnosis of IBD were recruited to complete a voluntary anonymous questionnaire. RESULTS: 27% of the surveyed participants reported use of cannabis. Of these, 39% reported moderate knowledge and 53% reported little to no knowledge of medical cannabis. The majority did not discuss cannabis use with their physician (78%), and most saw improvement of their symptoms (68%). CONCLUSION: Cannabis is frequently considered by patients as a treatment option for IBD but most have limited knowledge about its use. The low number of patients that discuss cannabis use with their physician suggests the need for physician awareness of unreported use. It should also lead to the development of strategies for patient orientation regarding the uses, properties, and expectations of cannabis as a therapy.
