Association Between Smoking Cessation Duration and Heated Tobacco Product Use Among People Who Formerly or Never Used Combustible Cigarettes in Korea

This study identifies patterns consistent with higher odds of current heated tobacco product (HTP) use among people who formerly used combustible cigarettes (PWFU-CC), particularly those with longer cessation durations. These findings highlight the importance of extending cessation support beyond people who currently use CC to include PWFU-CC. Public health surveillance should systematically monitor HTP use among PWFU-CC, and tobacco control policies should consider regulatory and educational strategies that specifically address novel nicotine products to better safeguard long-term cessation outcomes.
