This study systematically reviewed papers that evaluated flavored tobacco sales policies implemented in the United States during 2010-2019. From these papers, the authors developed a model to assess outcomes, assigned quality-of-evidence ratings to outcomes, and identified factors that might explain weak or inconsistent findings. Moderate- to high-quality evidence existed to associate policy implementation with reduced availability, marketing, and sales of restricted tobacco products and decreased adult and youth use of these products. However, these policy effects might be weakened by implementation challenges, tobacco industry reactions, and consumer attempts to engage in illicit purchases. Read the paper
