The Packaging and Labeling of Cannabis Edibles: Opportunities for Professional Communication Researchers

Michael J. Madson Arizona State University

Abstract

Introduction: As demand for cannabis edibles increases worldwide, researchers have called for evidence-based packaging and labeling. To assist in these efforts, this integrative review focused on two questions. 1. What aspects of edibles packaging and labeling has the empirical literature covered across disciplines, and how? 2. How might professional communication researchers build on that empirical literature, addressing consumer and industry needs? Research methodology: The methods followed Whittemore and Knafl, who described five stages for integrative reviews: problem identification, literature search, data evaluation, data analysis, and presentation. These methods, supplemented with guidance from Arksey and O'Malley, involved searches in seven relevant databases, producing 341 total returns. The final corpus consisted of 25 empirical studies. I constructed tables of these studies to facilitate iterative comparisons and synthesis. Results/discussion: The final corpus covered five aspects of packaging and labeling: label accuracy; visual content, appeal, and compliance; comprehension of serving size and dosage; perceptions of warnings; and possible enhancements through innovative technologies. The most common intervention types were laboratory analyses (n = 8), followed by surveys paired with experimental tasks (n = 7) and content analyses (n = 4), two of which included a compliance audit. Conclusions and further research: Based on current literature, more empirical studies are needed overall as well as more geographic and linguistic coverage. These needs align with our field's calls for more experimental and quasi-experimental research, alongside long-standing commitments to translation and localization, including participatory localization. As in other fields, future studies should emphasize child and youth protection as well as label accuracy.
