Parkinson Society British Columbia is proud to connect our community with the resources and tools they need to live well. Since Parkinson's disease (PD) can present differently in each individual, the Society endeavours to maintain impartiality when providing information on treatments, therapies, and medications to our community.

Every person with PD has unique needs, and may respond differently to clinical interventions. However, Parkinson Society BC does not recommend seeking out alternative interventions without the guidance of your primary care physician. Further, we do not endorse treatments, therapies, or medications not backed by extensive and credible research and clinical studies, or interventions not approved by Health Canada.

Position Statement of Parkinson Society British Columbia on Cannabis

As of October 17, 2018, the federal government, under Bill C-45, has legalized the purchase and consumption of marijuana (also referred to as cannabis) for Canadians.  

If you are considering the medical use of marijuana or its derivatives for Parkinson’s disease, it should be noted that to date, there have been no studies conclusively stating any benefits of cannabis for the treatment of symptoms. While smaller scale studies have been executed, study size and design have resulted in unreliable outcomes.

As with all drugs, the consumption of cannabis has potential side effects, including the possibility of exacerbating existing symptoms. If you are considering the medical use of marijuana for Parkinson’s disease, it is recommended that you consult with your healthcare team to discuss whether cannabis may be an option for your unique situation. Your healthcare team can help you assess the potential risks and/or benefits of cannabis by providing information and guidance based on the latest research.
