BACKGROUND: Experimental evidence suggests the endogenous cannabinoid system may
protect against colonic inflammation, leading to the possibility that activation
of this system may have a therapeutic role in inflammatory bowel disease (IBD).
Medicinal use of cannabis for chronic pain and other symptoms has been reported
in a number of medical conditions. We aimed to evaluate cannabis use in patients
with IBD. METHODS: One hundred patients with ulcerative colitis (UC) and 191
patients with Crohn's disease (CD) attending a tertiary-care outpatient clinic
completed a questionnaire regarding current and previous cannabis use,
socioeconomic factors, disease history and medication use, including
complimentary alternative medicines. Quality of life was assessed using the
short-inflammatory bowel disease questionnaire. RESULTS: A comparable proportion
of UC and CD patients reported lifetime [48/95 (51%) UC vs. 91/189 (48%) CD] or
current [11/95 (12%) UC vs. 30/189 (16%) CD] cannabis use. Of lifetime users,
14/43 (33%) UC and 40/80 (50%) CD patients have used it to relieve IBD-related
symptoms, including abdominal pain, diarrhoea and reduced appetite. Patients were
more likely to use cannabis for symptom relief if they had a history of abdominal
surgery [29/48 (60%) vs. 24/74 (32%); P=0.002], chronic analgesic use [29/41
(71%) vs. 25/81 (31%); P<0.001], complimentary alternative medicine use [36/66
(55%) vs. 18/56 (32%); P=0.01] and a lower short inflammatory bowel disease
questionnaire score (45.1±2.1 vs. 50.3±1.5; P=0.03). Patients who had used
cannabis [60/139 (43%)] were more likely than nonusers [13/133 (10%); P<0.001 vs.
users] to express an interest in participating in a hypothetical therapeutic
trial of cannabis for IBD. CONCLUSION: Cannabis use is common amongst patients
with IBD for symptom relief, particularly amongst those with a history of
abdominal surgery, chronic abdominal pain and/or a low quality of life index. The
therapeutic benefits of cannabinoid derivatives in IBD may warrant further
