This paper explores the effectiveness of using Regulatory Sandboxes (RS) to legalize THC edibles in Germany. While RSs have been extensively studied in sectors like Fintech and Healthtech, their application in introducing novel cannabis products or services remains underexplored. Utilizing Qualitative Comparative Analysis (QCA) across three countries namely Brazil, the state of Arizona and Thailand, we identify potential conditions for successful implementation of RS in the cannabis industry. Consequently, we propose the establishment of a tailored RS in Germany for cannabis edibles, aiming to foster innovation and drive revenue within the cannabis sector. The paper introduces a novel concept and paves the way for more research in the fields of RS and cannabis.
