Our evidenced-based, harm reduction research study will be led by an international team of renowned researchers and physicians based in both Canada and the United States.


National Access Cannabis operates health centres dedicated to assisting patients throughout Canada by facilitating the process of obtaining a medicinal cannabis prescription. We assist Canadians in maneuvering the ever changing Medical Marijuana Purposes Regulations (MMPR) system by providing up to date information on Health Canada approved licensed producers.


Founded by President and CEO Dr. Pritesh Kumar, PhytoSciences was conceived to represent patients and to provide clinical trial solutions and quality control services to the medical cannabis industry. Phytoscience’s primary mission is to promote cannabinoid research, establish standards within the cannabis testing sector and serve as a global leader in ethical laboratory and testing practices.

Results to be published

National Access Cannabis, in collaboration with PhytoSciences Consulting, a U.S. company specializing in clinical trial design pertaining to medical cannabis, will be establishing the first two-year pharmacovigilance project to monitor outcomes and adverse events related to the use of cannabis for medical purposes in Canada. This project will provide important observational data to support future evidenced-based clinical trials.


We encourage physicians to enroll suitable patients, ( patients that use opioids and may benefit from medicinal cannabis treatment) in this study.
