Cannabis Users Improve Bladder Function Symptoms in Patients with Multiple Sclerosis 


Recently, researchers from the University of Calgary conducted an exploratory study to assess the relationship between cannabis use and the improvement of bladder function symptoms in patients with Multiple Sclerosis (MS). More than 2,000 people with MS from the MS Clinic in Calgary were contacted by email and 775 responded. Among the 19 participants who reported bladder symptoms as a main reason for cannabis use, 89.5% reported “better” bladder symptoms when using cannabis. Cannabis consumption in the past 3 months was associated with a two-fold increased odds of reporting improvement in urinary frequency, urinary urgency, bladder leakage and wetness, pad use and bladder emptying. Although the sample size is small, this pilot study provides some initial glimpses into real world therapeutic use of cannabinoids among patients with MS for bladder symptoms.
