Patients' perspectives on marijuana use for inflammatory bowel disease: a multicenter survey.

Background: As marijuana use is rising among patients with inflammatory bowel disease (IBD), so is interest in its potential use as a therapeutic agent. We sought to survey IBD patients regarding marijuana use, self-reported impact on IBD symptoms, and perceptions of safety.

Methods: A multicenter anonymous survey was administered to patients with IBD between October 2020 and June 2021. The 70-question survey collected demographic variables, clinical variables, attitudes about marijuana, and perceptions of its safety and efficacy in IBD. Participants were classified by their marijuana use: "rarely/never," "current," and "former". Percentage and chi-square tests were used to compare categorical variables between the 3 groups, and means and 2-group ANOVA were used for continuous variables.

Results: Of 181 patients surveyed, 166 were eligible for the study. Of these, 70 (42.2%) participants were rare/never marijuana users, 44 (26.5%) were current users, and 52 (31.3%) were former users. Fifty-three percent thought marijuana would help with IBD inflammation and 80% thought it would help with IBD pain. Over 70% of patients from all groups thought marijuana had a low-to-moderate risk of harm, and 69.6% of the participants who never or rarely used marijuana thought marijuana was addictive, compared to 20.5% of the current users and 44% of the former marijuana users.

Conclusions: While many patients thought marijuana use helps with IBD-related pain and inflammation, many expressed concerns about addiction to marijuana and a possible risk of harm. Further studies are needed to examine the benefit and harm of marijuana in IBD.
