A Cross-Sectional Survey of Cannabis Use and Utility Among Patients Experiencing Dizziness.

Background/

Objective

Dizziness is managed using various therapies, including lifestyle changes, nutritional supplementation, pharmaceutical therapies, and physical therapy, each offering differing efficacy. With legalization of cannabis in Canada, patients are exploring its use in treating their dizziness and related symptoms. Limited knowledge exists regarding usage patterns, forms, doses, and effects on these symptoms. The current study aims to examine cannabis use in patients experiencing dizziness.

Methods

We conducted a cross-sectional study at the Ottawa Hospital outpatient neuro-otology clinic. Eligible participants included new patients presenting with a primary complaint of dizziness and follow-up patients reporting new-onset dizziness. Participants completed a questionnaire capturing demographic data, dizziness and related symptoms, attitudes toward cannabis use, consumption patterns, and its perceived effects on their symptoms.

Results

Of 154 participants, 118 (77%) expressed willingness to consider cannabis for dizziness and 78 (51%) reported previous cannabis use. Of those patients, 44 (56%) consumed it recreationally, largely via smoking (29/78, 37%). Approximately 21% of these patients reported a moderate-large subjective relief from dizziness after use of cannabis. The most common diagnoses amongst cannabis users were migraine/vestibular migraine (24%), persistent postural perceptive dizziness (22%), and benign paroxysmal positional vertigo (17%). Other related symptoms relieved by cannabis included sleep (28/78, 36%), emotional difficulties (17/78, 22%), neck pain/stiffness (14/78, 18%) and headaches/migraines (9/78, 12%).

Conclusions

There is generally a positive attitude towards cannabis use in treating dizziness amongst patients, with a subset of patients reporting a subjective improvement of dizziness and its related symptoms, such as sleep and emotional difficulties.
