PainRelief.com: What is the background for this study?
Response: Canada legalized recreational, or non-medical, cannabis in October 2018. Legalization in Canada took a phased approach initially, only the sale of flower-based cannabis products and oils was permitted and there were very few legal cannabis stores and legal sales. Starting in early 2020, Canada allowed the sale of expanded products (e.g. cannabis edibles, vape pens, concentrates), and the number of retail stores began expanding. In this study, we took advantage of this evolution of the legal cannabis market to understand how different phases of legalization were associated with hospitalizations due to cannabis.
