In recent years, scholars of applied public policy have published a growing number of studies regarding state tobacco policymaking. This article analyzes the research findings, data sources, and methodological approaches of this applied and theoretical policy research, including numerous comprehensive state tobacco policymaking studies analyzing issues such as youth access enforcement, tobacco taxes, anti-tobacco education efforts, and clean indoor air programs. Other studies have focused on individual policymaking instruments designed to address state tobacco control issues, including tort reform, tobacco listed as a cause of death on death certifcates, tobacco sampling, promotion and advertising restrictions, and fire-safe cigarettes. This wealth of research into tobacco policymaking has contributed significantly to our understanding of federalism, policy diffusion, and iron triangles and issue networks.
