Cigarette smoking among young South Korean men has dropped sharply over the past decade, according to new data from the Korea Disease Control and Prevention Agency (KDCA). In 2024, 28.5% of men in their 30s and 22.6% of men aged 19 to 29 were cigarette smokers—declines of 19.5% and 16.1% respectively since 2015. Men in their 40s recorded the highest smoking rate at 36.9%, down from 45.8%.
The study also found that about 40% of men in their 30s used some form of tobacco in 2024, down only 4.9% from 2019. For men in their 40s, total tobacco use increased slightly despite a small decline in cigarette smoking, reflecting the growing shift toward alternative products.
Health officials attribute part of the trend to changing perceptions about harm. A September 2025 survey of students found that 32.2% believed e-cigarettes were less harmful—or not harmful at all—compared to cigarettes. While authorities welcome the decline in cigarette use, they warn that misconceptions about alternative products may slow broader tobacco harm-reduction progress.
