The National Health Promotion Act has focused on tobacco control, and the prevalence of adolescents who report having smoked combustible cigarettes within last 30 days has continued to decline from 2000 to 2014 9.4/5.6% (boys/girls) to 1.3/0.6% in junior high school students and 29.9/13.1% to 3.5/1.5% in high school students. Therefore, smoking control during adolescence is a crucial public health issue. Moreover, tobacco can be a gateway to other types of drug dependence. Smoking control is particularly critical among adolescents, as individuals who use tobacco at a young age are at a considerably higher risk of becoming subsequent smokers. Smoking is a preventable health risk factor that results in numerous diseases and deaths. Continuous monitoring and research are needed to investigate their influence as a possible gateway to tobacco smoking. Moreover, e-cigarettes might attract a broader range of groups to smoking. Dual use is common, and many adolescents use new products only. The prevalence of new tobacco-alternative products is growing in popularity among Japanese adolescents. Comparisons between different types of users indicated different backgrounds for combustible cigarette users and new product users. An examination of the combined use of the three products identified a high number of dual users. The rate of heat-not-burn tobacco use was lower relative to other products: 1.1% (0.5%) in junior high school and 2.2% (0.9%) in high school. The age-adjusted rate of ever (current) use of electronic cigarettes was 2.1% (0.7%) in junior high school and 3.5% (1.0%) in high school that of combustible cigarettes was 2.6% (0.6%) in junior high school and 5.1% (1.5%) in high school. In total, 64,152 students from 48 junior high schools and 55 high schools were included the analysis (school response rate = 56%, M age = 15.7 years, 53.9% boys). Then, the use of a combination of products and the characteristics of different types of products were examined. We calculated the prevalence of use for each type of tobacco product. The students completed an anonymous questionnaire at school. From the national school directory, 98 junior high schools and 86 high schools were randomly sampled throughout Japan. The 2017 Lifestyle Survey of Adolescents is a nationally-representative survey collected in Japan. This study aimed to clarify the prevalence of smoking among adolescents, including new types of tobacco-related products, and to compare the characteristics of their users. However, the prevalence and association of combustible cigarettes and new tobacco-related products have not yet been closely investigated among Japanese adolescents. In Japan, where a unique tobacco regulation system exists, the heat-not-burn tobacco market has been growing. Especially for adolescents, the increase in the use of electronic cigarettes is controversial, as its use may lead to established smoking. Nicotine & Tobacco Research, 2021.From among the global public health concerns, smoking remains one of the most crucial challenges. Nicotine delivery and user ratings of IQOS heated tobacco system compared to cigarettes, Juul and refillable e-cigarettes. * Research paper: Anna Phillips-Waller, Dunja Przulj, Francesca Pesola, Katie Myers Smith, Peter Hajek. IQOS could be as effective as refillable e-cigarettes, although study participants preferred refillable e-cigarettes.Īuthor Professor Peter Hajek from Queen Mary University of London said: "IQOS is likely to be useful to help smokers quit, particularly in countries like Japan, where e-cigarettes are banned but in countries where e-cigarettes are available, they are likely to remain the more popular choice." The study concludes that, for quitting smoking, IQOS may be less effective than the US version of Juul (the version sold in the UK has very low nicotine delivery because of EU regulations and so it is less likely to be useful). Compared to traditional refillable e-cigarettes, IQOS provided nicotine faster, but received less favourable ratings. It had also lower nicotine delivery than Juul, and was less effective in reducing urges to smoke. IQOS delivered less nicotine than cigarettes. The researchers compared nicotine delivery and user ratings of IQOS with those of cigarettes, Juul (the US version of a 'pod' based e-cigarette with high nicotine content), and refillable e-cigarettes. The newest study from Queen Mary University of London evaluates safety and effects of these products and has focused on the most popular "heat not burn" product, IQOS. However, for smokers to switch to these alternatives, the products need to provide what smokers expect from cigarettes. Devices that deliver nicotine without smoke inhalation have potential to help smokers who cannot or do not want to stop using nicotine to reduce dramatically the risk of smoking-related disease and death.
