I have worked in the Canadian medical cannabis space for the last four years and have had the pleasure of working with many different key cannabis opinion leaders. Dr. Caroline MacCallum brings a level of passion of caring for patients who have many times run out of treatment options for their chronic conditions. This tenacity to find solutions to help these patients reach their goals to be more productive and functional, is inspiring. My conversations with Caroline motivate me to learn more, do more and improve the care I provide my patients.

Upon graduation, Dr. MacCallum practiced pain and addiction medicine at both Vancouver General Hospital and Heartwood Addiction Program at BC Women’s Hospital.  In addition, she practiced complex pain at the both the CHANGEpain Clinic and BC Women’s Complex Chronic Disease Program.

Dr. MacCallum developed expertise in complex pain and addiction while working in a variety of pain clinics and hospital programs in Vancouver. She became particularly interested in complex diseases including; fibromyalgia, chronic fatigue, lyme disease, IBS, PTSD, pevlic pain, migraines and others. In working with these patients she realized that not all patients responded or tolerate on/off label prescription medications. Patients reported that cannabis was helpful at managing many symptoms including pain, anxiety, mood, sleep and nausea. This created a shift for Dr. MacCallum, from focusing on disease specific to symptom based management.

Dr. MacCallum is a clinical instructor in the dept of Medicine, adjunct professor in the faculty of pharmaceutical sciences program, and associate member in the dept of palliative Care at the University of British Columbia. She is the medical director at Greenleaf Medical Clinic where she has assessed and developed cannabinoid treatment plans for more than 3,000 patients using legal medical cannabis approved by Health Canada.

She is a coauthor of the publication Practical Consideration for Medical Cannabis Administration and Dosing which is the first of its kind on medical cannabis dosing. She has presented internationally on the topic of cannabis dosing and cannabis and opioid.  She is the expert for several medical cannabis courses; has qualified as a medical cannabis expert and testified in arbitration for a claim involving a challenge to Health Canada’s 24-hour rule for cannabis impairment.

She is working with university research groups, hospitals, health benefit programs, provincial and national committees to create; cannabis guidelines, safe THC prescribing practices, clinical trials, patient registries and adverse event monitoring.

She is particularly interested in studying cannabis as a therapeutic option for complex conditions, as a substitute for opioid, for deprescribing, standardized product and testing, and impairment.
