Legal vs. Illegal Cannabis Markets: A Comparative Analysis of Prices, Product Diversity, and Accessibility
David Décary-Hétu, Catherine Arseneault

The legalization of cannabis aimed to regulate the market, ensure product safety, and reduce illegal sales. However, the persistence of the illicit market raises questions about the competitiveness of the legal framework. This study presents a comparative analysis of cannabis prices, product diversity, and accessibility between the legal and illegal online markets. By examining a dataset of product listings from both sectors, we assess price variations, product availability (flowers, edibles, concentrates, CBD/THC ratios), and purchasing conditions. Our findings highlight key discrepancies in cost structures, consumer preferences, and regulatory barriers that may influence market choices. The study discusses policy implications, particularly whether taxation and regulatory constraints are limiting the legal market’s ability to displace illicit sales. We propose recommendations for balancing public health objectives with economic sustainability to enhance the legal market’s attractiveness and effectiveness in achieving its intended goals.
