E-Cigarettes Use Behaviors in Japan: An Online Survey

Electronic cigarette (e-cigarette) use has become increasingly widespread throughout the world, including in Japan. However, little is known about how e-cigarettes are used in Japan, a country with heavy restrictions on nicotine-containing e-liquids and/or vaping products. This study examined e-cigarette use (e-cigarette use duration, frequency of use, device type, electrical resistance, nicotine use, favorite e-liquid flavors) among users in Japan, through an online survey using a web-based self-reported questionnaire which included questions about sex, age, combustible cigarette and heated tobacco product (HTP) use behaviors. Of 4689 e-cigarettes users analyzed, 93.5% were men and 52.9% had been using e-cigarettes for 1–3 years. Over 80% used e-cigarettes every day; 62.3% used nicotine liquid, and half of the nicotine liquid users used nicotine salt. The most popular liquid flavor was fruit (prevalence: 68.1%), followed by tobacco (prevalence: 48.4%). While 50.9% were e-cigarette single users, 35.2% were dual users (e-cigarettes and cigarettes or HTPs) and 13.8% were triple user (e-cigarettes, cigarettes and HTPs). This is the first comprehensive survey of Japanese e-cigarette users and our finding suggest more than half use nicotine liquid, although e-cigarettes containing nicotine liquid have been prohibited by the Pharmaceutical Affairs Act since 2010 in Japan. The study also showed 49.1% of participants used cigarettes and/or HTPs concurrently (dual or triple users).

Use of electronic cigarettes and heated tobacco products during the Covid-19 pandemic

Only a few studies investigated changes in electronic cigarette (e-cigarette) and heated tobacco product (HTP) use during pandemic restrictions. We conducted a web-based cross-sectional study of a representative sample of 6,003 Italian adults during the strictest phase of the Covid-19 lockdown (April–May 2020). Participants were asked to report changes in e-cigarette and HTP use compared to before the pandemic. E-cigarette users increased from 8.1% to 9.1% and HTP users from 4.0% to 4.5%. Among e-cigarette non-users before lockdown, 1.8% started using e-cigarettes during lockdown. New users were more frequently younger (p for trend 0.001), men (odds ratio, OR 1.56; 95% confidence interval, CI: 1.03–2.34), cannabis users (OR 2.35; 95% CI: 1.33–4.13), gamblers (OR 3.34; 95% CI: 2.18–5.11) and individuals with anxiety symptoms (OR 1.58; 95% CI: 1.00–2.52). 1.0% of HTP non-users started using it during lockdown. New users were less frequently current than never cigarette smokers (OR 0.19; 95% CI: 0.06–0.61) and more frequently gamblers (OR 2.23; 95% CI: 1.22–4.07). E-cigarettes and HTPs played little role as smoking cessation tools for hardcore smokers but rather provided opportunities for young never smokers to engage in socially acceptable activities, perhaps reflecting the obstacles they faced in obtaining other addictive substances during confinement.

Case Report: Nicotine Addiction-Adolescence obsession

Nicotine dependence is a chronic relapse defined as a compulsive desire to use it, regardless of social consequences, loss of control over intake, and appearance of withdrawal symptoms. Nicotine dependence develops over time as a person continues to use nicotine. The most commonly used tobacco product is cigarettes, but any form of tobacco use and use of e-cigarettes can lead to dependence. Nicotine dependence is a serious public health problem because it causes continued tobacco use, which is one of the leading preventable causes of death worldwide, causing more than 8 million deaths per year. The result of the journal review is that preventing the use of tobacco products among adolescents is critical to ending nicotine addiction worldwide. The impact caused by nicotine tends to be bad, so stopping is the way out. Different levels of influence should be considered in interventions aimed at adolescent smokers, including psychological influences, addictions, peers and parents. This review article contains about the effect of nicotine on adolescents and what strategies can be done to stop the problem.

Comparison of 3R4F cigarette smoke and IQOS heated tobacco product aerosol emissions

In this study, the smoke from a 3R4F research cigarette and the aerosol generated by the Heated Tobacco Product IQOS, also referred to as the Tobacco Heating System (THS) 2.2 in the literature, were compared. The objective was to characterize the gas and suspended particulate matter compositions in the mainstream smoke from a combusted 3R4F cigarette and in the aerosol generated by IQOS during use. The results indicated that the determined aerosol emissions from IQOS were notably lower than in the cigarette smoke under a Health Canada Intense puffing regimen. As an interesting detail in this study, the maximum nicotine concentrations within a puff were practically the same in both the 3R4F smoke and the IQOS aerosol, but the average concentration was lower for the IQOS aerosol. For both products, water constituted a significant proportion of the particulate matter, although it was substantially higher in the IQOS aerosol. Furthermore, combustion-related solid particles observed in the 3R4F smoke contained elements such as carbon, oxygen, potassium, calcium, and silicon. In contrast, IQOS aerosol particulate matter was composed of semi-volatile organic constituents with some minor traces of oxygen and silicon. The particulate matter found in the IQOS aerosol was volatile, which was especially noticeable when exposed to the electron beam of the scanning electron microscope (SEM) and Transmission Electron Microscope (TEM).

The effect of the fraction of used tobacco raw materials on the quality of shisha tobacco

Due to the rapid growth in the production and consumption of shisha tobacco in the Russian Federation, it has become necessary to improve the technology using optimal ingredient composition in order to create a high-quality and safe tobacco product. The aim of the research is to improve the technology of manufacturing shisha tobacco based on the optimization of its ingredient composition; to study the influence of the fractional composition of raw tobacco on its quality indicators. Fractional composition of raw tobacco in the production of shisha tobacco, as well as for other tobacco products, is important and affects its quality characteristics. Virginia and Burley tobaccos of the American type are the most demanded ones in the manufacture of shisha tobacco [1]. Sometimes oriental-type tobaccos are used in the bag, which are distinguished by high taste and aromatic qualities. Due to the fact that recently there has been an increase in the demand for Doha Arabian tobacco raw material (this tobacco is known as a high-quality product with a high strength and a pleasant, full and harmonious taste), the idea has arisen to manufacture prototypes of shisha mixtures in which Doha tobacco is used [2]. The article presents the research results: to determine the optimal ingredient composition of hookah tobacco; to study the optimal fractional composition of raw tobacco of various types. As a result of the research the chemical composition of raw tobacco of various types has been analyzed, the tasting and organoleptic evaluation of the prototypes carried out and the tobacco raw material most suitable for the production of shisha tobacco determined; the nicotine content in the condensate of prototypes of shisha mixtures with different fractions of raw tobacco determined; the optimal fractional composition for various types of tobacco raw materials, necessary for the production of a quality product determined.

Classifying the comprehensiveness of flavoured tobacco sales restrictions: development and application of a tool to examine US state and local tobacco policies

ObjectivesComprehensive tobacco control policies with minimal exemptions can reduce tobacco use and sales. Many states and localities have adopted flavoured tobacco product (FTP) sales restrictions. This study describes the development and application of a schema to characterise the comprehensiveness of these FTP sales restrictions.DesignWe coded state and local FTP sales restrictions enacted June 2007–March 2021 for retailer, tobacco product, and flavour inclusions and exemptions. Guided by FTP literature, legal resources and meetings with FTP policy experts, we developed a six-level classification scheme to characterise coded FTP policies from least to most comprehensive. We present descriptive statistics of FTP policy features and comprehensiveness.ResultsAs of 31 March 2021, 7 state-level and 327 local-level FTP sales restrictions were enacted in the USA. Most state-level policies (71.4%) were categorised in the second lowest comprehensiveness category; local policies most commonly fell within the lowest (48.9%) or highest (26.0%) comprehensiveness categories. Across jurisdictions, adult-only retailers were most frequently exempted from the FTP sales restrictions (state: n=1, 14.3%; local: n=184, 56.3%); and most jurisdictions included electronic cigarettes (e-cigarettes) as a banned product (state: n=6, 87.5%; local: n=227, 100%). While just over half of state (n=4, 57.1%) and local (n=169, 51.7%) sales restrictions included menthol e-cigarettes, most excluded menthol cigarettes and/or menthol smokeless tobacco.ConclusionsComprehensiveness of FTP sales restrictions in the USA varies widely. Current and future FTP policies would be strengthened by including all flavours and all tobacco products—particularly menthol cigarettes—and by avoiding exemptions for certain retailers, particularly adult-only retailers.

Cheaper tobacco product prices at US Air Force Bases compared with surrounding community areas, 2019

IntroductionIn March 2017, the US Department of Defense (DoD) implemented a policy requiring all military stores to set tobacco prices equal to ‘prevailing prices’ in the ‘local community’ adjusted for state and local taxes. We compared tobacco product prices in a sample of retailers located on five Air Force Bases (AFBs) in Texas and Mississippi with those sold in nearby off-base stores.MethodsWe constructed a list of on-base and off-base tobacco retailers. Off-base retailers included stores that were located within a 1.5-mile road network service area from main AFB gates. Between July and September 2019, a trained auditor visited 23 on-base and 50 off-base retailers to confirm tobacco product sales, and documented the price of cigarettes and Copenhagen smokeless tobacco. For each area, the median price for each product, as well as the difference in median prices by on-base versus off-base status, was calculated.ResultsThe median price of cigarettes and smokeless products was cheaper at on-base retailers. All products were cheaper at on-base stores in Fort Sam Houston and Lackland AFB. Similarly, all products were cheaper in on-base stores at Keesler AFB, with the exception of Marlboro Red packs ($0.22 more), and at Sheppard AFB with the exception of cheapest cigarette cartons ($6.26 more).ConclusionDespite the implementation of the new DoD policy, tobacco products are cheaper in on-base retailers compared with off-base retailers. Refining of the definitions used and improved compliance with the new DoD policy are needed.
