Background: Cigarette smoking is one of the leading global causes of premature and preventable death. In Brunei Darussalam, smoking-related diseases have been a primary cause of mortality for the past three decades. Despite the increasing efforts that have been made in recent years to reduce the consumption of tobacco products in Brunei, the prevalence of adolescent smoking cigarette, however has risen alarmingly, from 8.9% in 2013 to 11.4% in 2014, with a higher prevalence found in males (17.8%) than in females (4.8%). In response to the need for more effective smoking prevention programmes in Brunei, this study sought to explore factors that influence Bruneian male adolescents to start and continue smoking. Materials and Methods: A qualitative study using focus group discussions (FGDs) as the data collection method was conducted from October to November 2015. A total of 43 studentss, comprising 31 smokers and 12 non-smokers, aged 13-17 years, from two government secondary schools in Bandar Seri Begawan, participated in six FGDs. Discussions were recorded and translated. Transcripts were entered into NVivo10, before thematic analysis was conducted. Results: We identified three themes under the core construct of 'factors influencing smoking initiation' ('family as teachers', 'overt pressure from peers' and 'perceived smoking has many advantages') and three themes under the core construct of 'factors influencing smoking continuation' ('craving and addiction', 'smoking as a 'social activity' and 'easy accessibility of cigarettes'). Conclusions: Based on the findings, it is recommended that future prevention activities should be embedded in a comprehensive approach, involving all stakeholders within a community, and should be focused towards bringing a change in smoking and parenting behavior of parents, social norms within the culture towards all population levels, and at strengthening the existing non-smoking policies in schools and other public places where young people congregate.

Transfer of nicotine into the mails stream of smote in Korean commercial cigarettes was investigated. The mass transfer of nicotine into tile main stream of smote and accumulation of nicotine in cigarette filler got higher as the puffing number increased. Only about 14oyo of nicotine ill a cigarette was puffed into mouth end. and the rest of the nicotine went to side stream of smote or converted to other volatile bases.

Semiquantitative analysis by ICP-MS has proven to be a powerful tool for fast screening, in addition, it does not require the element of interest to be present in the calibration standard, making it especially useful for the analysis of unknown samples. In this study, seven cigarette samples were analyzed by the rapid semi-quantitative analysis method based on the ICP-MS. For each cigarette sample, cut tobacco, cigarette paper, filter (before and after smoking), and smoke condensate were analyzed. The accuracy of the analysis technique was evaluated by comparing results obtained from Calibration Check Standard(CCS) and calibration method. Relative Percentage Error(RPE) value of all elements measured for three CCS showed a stable result of less than ${\pm}20%$. Compared to full quantitative analysis by calibration method, the results for cigarette samples showed average error within ${\pm}15%$.

Objectives: We investigated the clustering of selected lifestyle factors (cigarette smoking, heavy alcohol consumption, lack of physical exercise) and identified the population characteristics associated with increasing lifestyle risks. Methods: Data on lifestyle risk factors, sociodemographic characteristics, and history of chronic diseases were obtained from 7,694 individuals ${\geq}20$ years of age who participated in the 2005 Korea National Health and Nutrition Examination Survey (KNHANES). Clustering of lifestyle risks involved the observed prevalence of multiple risks and those expected from marginal exposure prevalence of the three selected risk factors. Prevalence odds ratio was adopted as a measurement of clustering. Multiple correspondence analysis, Kendall tau correlation, Man-Whitney analysis, and ordinal logistic regression analysis were conducted to identify variables increasing lifestyle risks. Results: In both men and women, increased lifestyle risks were associated with clustering of: (1) cigarette smoking and excessive alcohol consumption, and (2) smoking, excessive alcohol consumption, and lack of physical exercise. Patterns of clustering for physical exercise were different from those for cigarette smoking and alcohol consumption. The increased unhealthy clustering was found among men 20-64 years of age with mild or moderate stress, and among women 35-49 years of age who were never-married, with mild stress, and increased body mass index (>$30\;kg/m^2$). Conclusions: Addressing a lack of physical exercise considering individual characteristics including gender, age, employment activity, and stress levels should be a focus of health promotion efforts.

It has been proposed that differences in diet between smokers and nonsmokers may partially explain the positive association between cigarette smoking and chronic diseases such as cancer and coronary heart disease. To investigate the potential for this confounding, the authors studied the relation between cigarette smoking and dietary pattern including nutrient intake in 152 Korean elderly people aged 59∼84years. Dietary intake was determined by a 24-hour recall method and a food frequency questionnaire. Male smokers were lighter than nonsmokers and had a lower body mass index(BMI)(p<0.05). But there were no differences in body weight and BMI between female smokers and nonsmokers. Female smokers had lower intakes of energy and carbohydrates than nonsmokers(p<0.05), but in male, smokers and nonsmokers did not show the difference in energy intake. The mean intake of fiber, protein, fat, minerals, and vitamins did not vary significantly by smoking status. However, both male and female smokers consumed fewer fruits than nonsmokers and ate fresh fruits less often than nonsmokers. The total food frequency score which reflect dietary quality of smokers was lower than those of nonsmokers(p<0.05). Male exsmokers' diet were similar to those of smokers, but in female, dietary patterns of exsmokers were similar to those of nonsmokers. These results confirm that elderly smokers have partially different nutrient and food intake patterns from nonsmokers. The decreased ingestion of fruits and less balanced diet by cigarette smokers could contribute to their increased risks of chronic disease compared with those by nonsmokers. The increased ingestion of nutrients and improved nutritional balance in the diet of exsmokers may help to reduce their risks as well.

There are over 4,000 different chemicals in cigarette smoke, including nicotine and tar. These compounds influence on lung tissue directly or indirectly. In this study, we have examined whether an aqueous extract of Se-Yeon-Eum (SYE), composed of Oriental medicine that has been known to be effective to symptom by smoking, inhibits nicotine- or cigarette smoke extract (CSE)-induced cytotoxicity in human embryonic lung fibroblast, MRC-9. Assessment of cell viability using 3-(4,5-dimethythiazol-2-yl)-2,5-diphenyltetrazolium bromide colorimetric assay indicated that SYE inhibited not only nicotine-induced cytotoxicity but also CSE-induced cytotoxicity. These results suggest the possibility that the use of SYE may be useful for improvement of many symptoms by smoking.

Biomarkers could be critical and useful tools for assessing the biological effects of smoking and detecting differences between potentially reduced exposure product (PREP) and conventional cigarettes. Smoking-related biomarkers can be classified into three categories as biomarkers of exposure, biomarkers of effects, and biomarkers of potential harm. When compared with the biomarkers of effects or harm, the biomarkers of exposure for chemical constituents of cigarette smoke are well established and characterized. In addition, they could offer the important information in understanding how cigarette smoke interacts with biological molecules and causes the disease to human. Therefore, we provide an overview of 6 biomarkers of exposure (Nicotine and nicotine metabolites, Carboxyhaemoglobin, NNAL (4-(methylnitrosoamino)-1-(3-pyridyl)-1-butanol) and NNAL - glucuronide, 3-Hydroxypropyl-mercapturic acid, and Monohydroxy-butenyl-mercapturic acids, and Urine mutagenicity) which were validated through extensive research and clinical experience. These reliable biomarkers could help identify the efficacy of PREP by predicting early toxicological effects and lead to improve it.

Lung cancer is the most prevalent global cancer, ${\sim}90%$ of which is caused by cigarette smoking. The LNT hypothesis has been inappropriately applied to estimate lung cancer risk due to ionizing radiation. A threshold of ${\sim}1\;Gy$ for lung cancer has been observed in never smokers. Lung cancer risk among nuclear workers, radiologists and diagnostically exposed patients was typically reduced by ${\sim}40%$ following exposure to <100 mSv low LET radiation. The consistency and magnitude of reduced lung cancer in nuclear workers and occurrence of reduced lung cancer in exposed non-worker populations could not be explained by the HWE. Ecologic studies of indoor radon showed highly significant reductions in lung cancer risk. A similar reduction in lung cancer was seen in a recent well designed case-control study of indoor radon, indicating that exposure to radon at the EPA action level is associated with a decrease of ${\sim}60%$ in lung cancer. A cumulative whole-body dose of ${\sim}1\;Gy$ gamma rays is associated with a marked decrease in smoking-induced lung cancer in plutonium workers. Low dose, low LET radiation appears to increase apoptosis mediated removal of $\alpha$-particle and cigarette smoke transformed pulmonary cells before they can develop into lung cancer.
