The study also evaluated associations between cannabis legalization and MC sales over time using a dynamic Difference-in-Differences (DiD) approach with multiple time periods. “Amidst the global shift toward cannabis legalization, this study examines medical cannabis (MC) sales as an indicator of economic activity and innovation”, states the study’s abstract. The dynamic DiD approach estimates the average association for legalizing countries across multiple time periods, enabling comparisons of post-legalization outcomes with those of non-legalizing countries. Legalization is associated with an average annual increase of 26.06 tons of MC sales in legalizing countries.”Event study estimates confirm a sustained growth trajectory in MC sales following legalization. Nonetheless, they highlight the potential economic relevance of cannabis legalization in expanding regulated markets and reshaping consumer behavior.
