Abstract

Objective: This study examines the public health and cancer prevention implications of the rapid proliferation of electronic nicotine delivery systems (ENDS) in South Korea, and discusses regulatory strategies grounded in empirical evidence. Method: Drawing on domestic and international literature, and national statistical data, the analysis synthesizes evidence on ENDS product characteristics, patterns of use, associated health risks, potential effectiveness for smoking cessation, and indicators of nicotine dependence. A comparative policy analysis further situates Korea’s tobacco control framework within the broader landscape of regulatory approaches adopted in other high-income countries. Results: Although ENDS eliminate combustion and may reduce exposure to certain carcinogens, their expanding use raises substantial public health concerns particularly with respect to youth nicotine initiation, dual use with combustible cigarettes, and uncertain long-term health effects. While some evidence suggests a possible role for ENDS in smoking cessation, the overall scientific evidence remains mixed, and robust longitudinal data are limited. Regulatory responses to ENDS vary widely across countries, with South Korea maintaining a relatively cautious regulatory stance. Conclusion: In light of the evolving evidence base and emerging population-level risks, a comprehensive and precautionary regulatory approach is warranted with particular emphasis on protecting adolescents, ensuring product safety, and reinforcing norms that support tobacco cessation.
