Tobacco use is the most important preventable cause of mortality in South Korea and worldwide. This study aimed to evaluate the tobacco control policies of the Moon Jae-in government, which was established in May 10, 2017. Before the Moon Jae-in government, the tobacco tax was raised by the Park Geun-hye government from 2,500 won to 4,500 won (80% increase), but the price of cigarettes was still much lower in Korea than in other high-income countries. Cigarette smoking has been prohibited in all restaurants and bars since 2015; however, smoking rooms are allowed. Only large buildings are smoke-free. Pictorial warnings on cigarette packages were introduced in December 2016; however, they cover only 30% of the main packaging. Smoking cessation services provided by health care facilities have been subsidized by public health insurance since 2015. However, the advertisement, promotion, and sponsorship of tobacco are not further regulated. Since the beginning of the Moon Jae-in government, there has been no further strengthening of major tobacco control policies except for limited expansion of smoke-free public places and introduction of a lung cancer screening program. The first government-level tobacco control policies by the Moon Jae-in government, announced in May 2019, included increasing the size of the pictorial warnings and introducing standardized packaging by 2025, along with incremental expansion of smoke-free public places with prohibition of smoking rooms. These moves are positive; however, they do not include increasing tobacco taxes and regulating advertisement, promotion, and sponsorship of tobacco, which together are the backbone of tobacco control policies. The Moon Jae-in government should strengthen comprehensive tobacco control policies, ncluding tobacco taxes and banning tobacco advertisement, promotion, and sponsorship, to protect public health.

Recently, fatal nicotine intoxications with electronic cigarette liquid have increased in Korea, but various kinds of cigarettes and smoking cessation aids may also cause fatal poisoning. We report cases of fatal nicotine intoxications involving causes other than the use of liquid nicotine. A 29-year-old woman (case 1) found dead in a hotel room with about 70 patches (21 mg dose) of nicotine on her body. Blood nicotine levels were 7.68 mg/L (heart) and 3.25 mg/L (femoral). A toxic level of zolpidem was also detected. A 28-year-old Uzbekistan man (case 2) was found dead in his uncle's room with his face covered with chewing tobacco. Blood nicotine levels were 7.3 mg/L (heart) and 4.6 mg/L (femoral). Blood alcohol level was 0.139%. A 55-year-old man (case 3) bit his tongue. As he was taken to the hospital, his wife put tobacco powders in his mouth for hemostasis, and he died of cardiac arrest. Blood nicotine levels were 2.01 mg/L (heart) and 0.96 mg/L (femoral). Nicotine-related deaths can be caused by various types of administration including transdermal and transmucosal routes, and relatively small doses may cause death, so meticulous investigation should be taken when such deaths are suspected.

BACKGROUND: Relapse is the common situation of smoking cessation attempts. There are few studies that analyzed the related factors of smoking relapse among military personnel. Thus, This study was performed to investigate factors related to smoking relapse among military personnel who participated smoking cessation clinics in Korea. METHODS: The study subjects were 19,874 military personnel who enrolled smoking cessation clinic from January in 2015 to December in 2017. Smoking cessation applied to criteria exhaled carbon monoxide and urine cotinine levels. Binominal logistic regression analysis was performed to confirm related factors of smoking relapse among military personnel who succeed to quit smoking. RESULTS: The smoking relapse rate of study subjects who succeeded in quitting smoking for 1-month was 15.3% after 3-months and 60.8% after 6-months follow-up. The factors associated with relapse smoking included implementing year, past year quit attempts, number or cigarettes smoked per day, regular exercise, blood pressure. Levels of nicotine dependence affected smoking relapse at 3-months follow-up. CONCLUSIONS: Tailored approaches are necessary to reduce the rates of smoking relapse for military personnel who succeeded to quit smoking shortly but relapse back to smoking.

OBJECTIVES: Smoking cessation decreases morbidity and mortality due to chronic obstructive pulmonary disease (COPD). Pharmacotherapy for smoking cessation is highly effective. However, the optimal prescription rate of smoking cessation medications among smokers with COPD has not been systemically studied. The purpose of this study was to estimate the national prescription rates of smoking cessation medications among smokers with COPD and to examine any disparities therein. METHODS: We conducted a retrospective study using National Ambulatory Medical Care Survey data from 2007 to 2012. We estimated the national prescription rate for any smoking cessation medication (varenicline, bupropion, and nicotine replacement therapy) each year. Multiple survey logistic regression was performed to characterize the effects of demographic variables and comorbidities on prescriptions. RESULTS: The average prescription rate of any smoking cessation medication over 5 years was 3.64%. The prescription rate declined each year, except for a slight increase in 2012: 9.91% in 2007, 4.47% in 2008, 2.42% in 2009, 1.88% in 2010, 1.46% in 2011, and 3.67% in 2012. Hispanic race and depression were associated with higher prescription rates (odds ratio [OR], 5.15; 95% confidence interval [CI], 1.59 to 16.67 and OR, 2.64; 95% CI, 1.26 to 5.51, respectively). There were no significant differences according to insurance, location of the physician, or other comorbidities. The high OR among Hispanic population and those with depression was driven by the high prescription rate of bupropion. CONCLUSIONS: The prescription rate of smoking cessation medications among smokers with COPD remained low throughout the study period. Further studies are necessary to identify barriers and to develop strategies to overcome them.

E-cigarettes, heat-not-burn (HNB) tobacco, and other new types of tobacco products are emerging in Korea. These products are particularly popular among smokers who are looking for less harmful means of tobacco consumption, and are highly relevant for existing tobacco control policies. E-cigarettes, which are electronic devices designed to allow the user to inhale nicotine as a vapor, are controversial in terms of their safety and effects on smoking cessation, as a variety of harmful substances have been detected in e-cigarette vapor. Due to policy differences in tobacco harm reduction, the regulations on e-cigarettes differ from country to country, and domestic regulations regulate e-cigarettes in a manner similar to conventional cigarettes. In contrast, HNB tobacco was introduced in Korea in June 2017, and is rapidly expanding in the market, as active marketing campaigns seek to communicate to consumers that HNB tobacco use involves no tar and is less harmful to health. However, the World Health Organization and several professional groups have argued that based on independent studies not supported by tobacco companies, HNB tobacco should be regulated in the same way as conventional cigarettes because there is no evidence that HNB tobacco is less harmful. Clinicians need to expand their understanding of new tobacco products so that they can provide appropriate counseling.

The Framework Convention on Tobacco Control (FCTC) entered into effect in 2005 and has been ratified by 181 parties. The major tobacco control policies included in the FCTC are increased tobacco taxes; smoke-free public places; bans on tobacco advertisements, promotion, and sponsorship; regulations of tobacco packaging and labeling; regulations and disclosure of tobacco component and emissions; public awareness campaigns about the adverse health effects of tobacco use; treatment of tobacco use and dependence; and bans on tobacco sales to minors. Since the FCTC was ratified, tobacco control policies have been strengthened worldwide, but with different effects for different policies. A high level of performance was achieved in 55% of the signatory countries for warnings about the hazards of tobacco and in 30% for monitoring tobacco control policies, but tobacco tax increases, smoke-free polices, and bans on tobacco advertisement, promotion, and sponsorship achieved high levels of success in only about 10% of the countries. Korea recently strengthened some tobacco control policies, including tobacco tax increases, mass media campaigns, pictorial warnings on tobacco packs, smoke-free bars and restaurants, and reimbursement for smoking cessation services provided by health care facilities. However, the price of cigarettes remains very low considering the nation's income level, and tobacco advertisements, promotion, and sponsorship are only partially restricted. Workplace smoke-free policies are limited to large companies. Only monitoring of tobacco control policies and smoking cessation services are at a high level in Korea. Comprehensive tobacco control polices need to be strengthened, and physicians should play a leading role.

Objective: To understand the current status of smoking and smoking cessation in persons aged 15 years and over in Beijing and evaluate the effect of 2015 Beijing Tobacco Control Regulation. Methods: In 2014 and 2016, based on the principles and methodology of the Global Adult Tobacco Survey. A total of 50 communities or townships were selected from 324 communities or townships in Beijing through multistage cluster sampling, and 2 community (village) committees from each community or township were selected with the method of probability proportional to size (PPS). A total of 100 surveillance sites were set, and 100 households were selected from each surveillance site by using simple random sampling. Data were collected through face-to-face interview from the eligible family members aged 15 years and over with the assistance of a tablet computer. Statistical analyses were conducted by using complex sampling analyses module of SPSS 20.0, with weights as a combination of sampling weights, non-response weights and post- stratification weights, for the calculation of current smoking prevalence, daily smoking prevalence, smoking cessation rate, etc. Results: A total of 8 484 and 9 372 valid questionnaires were obtained, respectively, in 2014 and 2016, with the response rate of 86.5% and 96.5%. The current smoking prevalence in persons aged 15 years and over was 23.4% in 2014, and 22.3% in 2016. According to the 6(th) national census data, the current smoking population decreased by 199 000 in Beijing. The proportion of daily smokers declined from 20.7% in 2014 to 19.2% in 2016. The daily number of cigarettes consumed by current smokers increased from 14.6 in 2014 to 15.4 in 2016. The smoking cessation rate was 14.9% in 2014 and 16.8% in 2016. The proportion of current smokers who had at least one smoking cessation attempt in the past 12 months increased from 22.3% in 2014 to 23.2% in 2016, and the proportion of current smokers who planned to quit smoking increased from 11.6% to 15.5%. Among the current smokers who had visited doctors in the past 12 months, the proportion of those having smoking cessation advice was 58.9% in 2014 and 59.2% in 2016. In 2016, among the current smokers who had attempted to quit in the past 12 months, 36.8% were aware of the smoking cessation clinics, and 29.5%were aware of the quitline. Among those who were aware, only 7.7% had actually visited the cessation clinics, and 5.5% had used the quitline. Conclusions: After the implementation of 2015 Beijing Tobacco Control Regulation for 1 year, the current smoking prevalence in persons aged 15 years and over showed decreasing. It is necessary to further prompt the expansion of smoking cessation service to cover more current smokers.

OBJECTIVE: The effect of transdermal nicotine patch on sleep physiology is not well established. The current study aimed to examine the influence of nicotine patch on homeostatic sleep propensity and autonomic nervous system. METHODS: We studied 16 non-smoking young healthy volunteers with nocturnal polysomnography in a double blind crossover design between sleep with and without nicotine patch. We compared the sleep variables, sleep EEG power spectra, and heart rate variability. RESULTS: The night with nicotine patch showed significant increase in sleep latency, wake after sleep onset, and stage 1 sleep; and decrease in total sleep time, sleep efficiency, and percentage of REM sleep. Also, spectral analysis of the sleep EEG in the night with nicotine patch revealed decreased slow wave activity in stage 2 and REM sleep and increased alpha activity in the first NREM-REM sleep cycle. Heart rate variability showed no differences between the 2 nights, but the low to high ratio (a parameter indicative of sympathetic nervous system activity) positively correlated with wake after sleep onset in night with nicotine patch. CONCLUSION: Transdermal nicotine patch significantly disrupts sleep continuity, sleep architecture, and homeostatic sleep propensity. The overactivation of the sympathetic nervous system may be responsible for these changes.

Graphic warning labels (GWLs) have been developed as a representative non-price policy to block such marketing. This study investigated the current state and effect of the global introduction of GWLs and examines the future tasks related to GWLs. We systematically reviewed literatures on GWL and a tobacco control strategy in the past fifteen years. The policy of enforcing GWLs has spread globally based on the Framework Convention on Tobacco Control. GWLs are more effective than text warnings and are implemented in over 70 countries. The policy has showed the impact of GWLs as a preventive effect on adolescents' smoking, inducement of smoking cessation, reduction in the amount of tobacco smoked, and reduction in smoking rates. The success of an anti-smoking policy can manifests itself as an effect of individual policies, the rise of tobacco prices, and the introduction of GWLs.

BACKGROUND: Hospitalization presents smokers with an opportunity to initiate smoking cessation. We studied the effect of inpatient counseling and follow-up after discharge on smoking cessation and assessed predictors of successful cessation. METHODS: This study included a total of 125 patients (118 male and 7 female) who were admitted to departments of neurology, cardiology, and pulmonology. They were referred to the smoking cessation clinic, and participated between September 2011 and February 2013. A counseling service lasting about thirty minutes was provided by the third-year family medicine residents during hospitalization. The follow-up counseling services, which were either by telephone or in-person physician counseling were provided at 1 week, 4 weeks, and 3 months. Smoking habits and nicotine dependency data were gathered using questionnaires, and patient information was collected from electronic medical records. RESULTS: The average age in the study was 57.9 +/- 10.2 years and duration of smoking was 35.9 +/- 11.7 years. Daily tobacco consumption was 23.5 +/- 13.2 cigarettes. The smoking cessation rate after 3 months was 42.4%. The only differences between patients in the successful cessation and failed groups were cause of admission (P = 0.039) and total number of counseling sessions after discharge (P < 0.001). In a multivariate analysis, smoking cessation was more likely when patients experienced more instances of follow-up after discharge (1-2 visits: odds ratio [OR], 8.186; 95% confidence interval [CI], 1.060 to 63.239; > or =3 visits: OR, 121.873; 95% CI, 14.462 to 1,027.055). CONCLUSION: Smoking cessation counseling during hospitalization and further follow-up by telephone or outpatient counseling after discharge contributed to an increased smoking cessation rate. The smoking cessation rate also tended to increase with total counseling numbers.
