Background: Tobacco use is a leading cause of countless deaths and disabilities worldwide. An estimated 11 million Korean adults were still using tobacco in 2020, according to the Korea National Health and Nutrition Examination Survey. This review aims to explain the current trends in tobacco use, sales, cessation, and control policies in South Korea.Current Concepts: Heated tobacco products (HTPs), a hybrid between conventional and electronic cigarettes, were first launched in South Korea in June 2017. Advertisements stating that HTPs are odorless, tar-free, and less harmful to health have caused sales of HTPs to grow quickly over the past 5 years, such that they account for about 15% of the total tobacco market. According to national smoking rate statistics and tobacco sales trends, declines in current smoking rates have slowed and even risen in some groups, and declines in total tobacco sales have slowed but also risen again during the coronavirus 19 pandemic. In addition, the number of visitors to smoking cessation clinics decreased just after the advent of HTPs and social distancing policies triggered by the coronavirus. Nicotine replacement therapy can serve as a drug therapy for smoking cessation, or bupropion and varenicline can be prescribed. Korea’s representative tobacco control policies include the tax increase policy, non-smoking area policy, cigarette pack warning picture policy, and support policy for visiting smoking cessation clinics.Discussion and Conclusion: There is a pressing need to reflect tobacco control policies in line with changes in tobacco user behaviors and tobacco company marketing strategies.

Current status of tobacco use, cessation and control policy in Korea

Background Although many studies have demonstrated that the first cigarette in the morning increases the prevalence of smoking-related morbidity, limited studies have examined the impact of time to first cigarette (TTFC) on the health-related quality of life (HRQoL). Thus, we assessed this relationship using nationally-representative data from the Korea National Health and Nutrition Examination Survey VII-1 (2016). Methods We conducted a cross-sectional study using data from 577 current male smokers aged 30-59 years, after excluding those with a certain disease. Participants were divided into four categories according to TTFC (≤5 min, 6-30 min, 31-60 min, >60 min). HRQoL was measured using self-reported EuroQol-5 (EQ-5D). The relationship between TTFC and EQ-5D index was analyzed using a multivariate-adjusted generalized linear model to assess how HRQoL varies according to TTFC. After adjusting for confounders, a multivariate-adjusted logistic regression analysis was performed to identify which of the five dimensions of the EQ-5D affected the HRQoL according to TTFC. Results The generalized linear analysis indicated that as TTFC decreased (6-30 min, 31-60 min vs. >60 min), the EQ-5D index score decreased significantly (P=0.037). Shorter TTFC (≤5 min vs. >60 min) was associated with higher pain/discomfort (odds ratio [OR], 3.82; 95% confidence interval [CI], 1.39-10.48) and anxiety/depression (OR, 7.58; 95% CI, 1.75-32.88). Conclusion Higher nicotine dependence was associated with impaired HRQoL. These results may be used to improve smoking cessation treatment outcomes.
