Abstract Introduction Although the use of combustible cigarettes has decreased in many urban regions of America, the use of electronic nicotine delivery systems (ENDS) has dramatically increased. ENDS, or electronic cigarettes (e-cigarettes), differ from combustible cigarettes given that there are no restrictions on flavorant additives in e-liquids. With 95% of ENDS users vaping flavored e-liquids, it is critical to understand how flavors alter vaping-related behaviors. We have previously shown that menthol and green apple flavors enhance nicotine reward-related behavior in a mouse model and in the present study have investigated how menthol and green apple flavors alter e-Vape self-administration behavior in male mice. Methods Adult C57/BL6J male mice were used in vapor-inhalation self-administration assays. Mice were assigned vaping e-liquids (6 mg/mL nicotine with or without menthol or green apple flavor) to escalate on a fixed-ratio 1 (FR1) schedule in daily 3-hour sessions to examine initiation-related behaviors. Following escalation, mice were transitioned to a FR3 and progressive ratio schedules in 3-hour sessions to examine reinforcement-related behaviors. Results Here we observed that male mice exhibited increased rates of self-administration escalation on a FR1 schedule when assigned to flavored e-liquids. Upon transition to FR3, mice continued to exhibit enhanced levels of reinforcement with flavored e-liquids. We also observed that mice self-administer zero-nicotine green apple flavored e-liquids. Conclusions These data provide additional evidence that ENDS flavors enhance vaping-related initiation and reinforcement-related behavior and promote the need to continue investigating the role ENDS flavors play in vaping-related behaviors. Implications There has been much discussion recently regarding the impact of flavors on vaping-related behavior. Our study here shows that flavors significantly enhance the acquisition and reinforcement of vaping-related behavior. This suggests that flavors in electronic nicotine delivery systems significantly increase the risk of addiction-related behaviors among users of vaping products.

В статье представлены актуальные данные экспериментальных и клинических исследований по изучению влияния различных средств доставки никотина в организм курильщика. Проведён сравнительный анализ воздействия табачных сигарет, электронных средств доставки никотина и системы нагревания табака IQOS на показатели здоровья и развития организма человека, а также лабораторных животных. Показано, что, несмотря на громкие заявления производителей альтернативных средств доставки никотина о полной безвредности их устройств, результаты экспериментальных исследований обнаруживают в них не только известные канцерогены, но и новые потенциально опасные вещества, которые не содержатся в обычных сигаретах, и влияние которых на организм достаточно не изучено. На данный момент имеются все основания полагать, что употребление электронных сигарет и IQOS может приводить к заболеваниям нервной, кроветворной, иммунной, дыхательной систем, а также к развитию онкологических заболеваний. The article presents current results of experimental and clinical studies focusing on effects of various nicotine delivery systems. The authors conducted a comparative analysis of the impact of tobacco cigarettes, electronic nicotine delivery devices, and IQOS tobacco heating systems on the health and development of humans and laboratory animals. The review of recent literature has shown that, despite ambitious statements of the manufacturers about complete safety of their devices, experiments have demonstrated that they release not only well-known carcinogens but also new, potentially hazardous substances. These substances are not contained in ordinary cigarettes, and their effects on the body has not been sufficiently studied. Presently, it seems very likely that the use of electronic cigarettes and IQOS can lead to diseases of the nervous, hematopoietic, immune, and respiratory systems as well as to oncological diseases.

The One

Introduction: The use of electronic nicotine delivery systems (ENDS) such as electronic cigarettes, vapour cigarettes, and vapour/hookah pens is rapidly increasing. The effectiveness of ENDS for smoking cessation and their safety, particularly amongst pregnant women, is largely unknown. Some women who use tobacco products in pregnancy, such as the one described in this case study, switch to ENDS assuming they are a safer alternative to smoking traditional cigarettes. Many obstetric providers do not screen for ENDS use and may miss an opportunity to counsel their patients about ENDS usage, side effects, or alternatives.Case Description: Motivated by concern for her baby's health, a 28-year-old patient reduced consumption of traditional cigarettes and began using ENDS shortly after learning she was pregnant. Her obstetric team did not screen for ENDS use and was unaware that she had started using ENDS. During the postpartum period, her providers ordered a tobacco cessation consult and the tobacco treatment specialist (TTS) discovered the patient's ENDS use as well as her desire to quit.Conclusions: In the absence of consistent screening by providers and a lack of safety data regarding ENDS use during pregnancy, women are often given little guidance in deciphering the potential risks and benefits of ENDS use. In this case, the patient turned to ENDS because she thought it was safer than smoking tobacco cigarettes and was unaware that there is limited research on ENDS safety. This case highlights the importance of updating clinical screening tools to include ENDS and the need for further research investigating the safety of ENDS use during pregnancy.

The Impact

Purpose This paper aims to describe the various government measures that regulate the market for novel tobacco harm reduction products (THRPs), with an emphasis on e-cigarettes [electronic nicotine delivery systems (“ENDS”)], and evaluates the public health impact of excise taxes levied on these products. Design/methodology/approach The paper reviews the economic research on the impact ENDS. Using cited evidence, the paper compares the tax treatment of ENDS and cigarettes and provides a simulation of potential lives that can be saved under alternative tax treatment of ENDS. Findings ENDS are considerably less harmful than cigarettes. Imposing the same tax burden on them (per unit of “harm”) as on cigarettes leads to poorer health outcomes. Differential tax treatment of ENDS will encourage more cigarette smokers to switch to ENDS and could save millions of lives worldwide. Research limitations/implications Country experiences with regulatory measures on ENDS are limited to those with high THRP penetration. The paper’s simulation analysis used evidence from a limited number of studies. Rigorous economic analysis is needed to understand how ENDS could save lives and could prevent expected one billion premature deaths by the end of this century. Originality/value The paper uses research evidence in its analysis of the impact that the differential taxation of cigarettes and ENDS would have. It also provides a rough estimate of the number of lives that could be saved if more smokers who are trying to quit can make the switch to ENDS.

Abstract Regulatory authorities have devoted increasing attention and resources to a range of issues surrounding the regulation of novel nicotine and tobacco products. This review highlights the inherent complexity of evaluating prospective policies that pertain to products that heat solutions containing nicotine but not tobacco leaf, sometimes referred to as electronic nicotine delivery systems (ENDS). The U.S. Food and Drug Administration (FDA) is compelled to incorporate a set of public health criteria in their decision-making, collectively referred to as the Population Health Standard. Adherence to this standard is necessary to estimate the impact of prospective ENDS policy decisions on net population harm associated with non-therapeutic nicotine products. For policies that are expected to decrease or increase ENDS use, application of the Population Health Standard requires a comprehensive assessment of the status quo impact of ENDS use on population health. Accordingly, this review first assesses the state of the evidence on the direct harms of ENDS and the indirect effects of ENDS use on smoking, particularly rates of initiation and cessation. After that, the example of flavor restrictions is used to demonstrate the further considerations that are involved in applying the Population Health Standard to a prospective ENDS policy. Implications This narrative review aims to inform regulatory considerations about ends through the prism of the population health standard. More specifically, this review: 1) describes and explains the importance of this approach; 2) provides guidance on evaluating the state of the evidence linking ends to the net population harm associated with non-therapeutic nicotine products; and 3) illustrates how this framework can inform policymaking using the example of flavor restrictions.

New Generation

Electronic nicotine delivery systems (ENDS) are rapidly growing in popularity among youth. ENDS are handheld devices that produce an aerosolized mixture from a solution typically containing concentrated nicotine, flavoring chemicals, and propylene glycol to be inhaled by the user. ENDS are marketed under a variety of names, most commonly electronic cigarettes and e-cigarettes. In 2014, more youth reported using ENDS than any other tobacco product. ENDS pose health risks to both users and nonusers. Nicotine, the major psychoactive ingredient in ENDS solutions, is both highly addictive and toxic. In addition to nicotine, other toxicants, carcinogens, and metal particles have been detected in solutions and aerosols of ENDS. Nonusers are involuntarily exposed to the emissions of these devices with secondhand and thirdhand aerosol. The concentrated and often flavored nicotine in ENDS solutions poses a poisoning risk for young children. Reports of acute nicotine toxicity from US poison control centers have been increasing, with at least 1 child death reported from unintentional exposure to a nicotine-containing ENDS solution. With flavors, design, and marketing that appeal to youth, ENDS threaten to renormalize and glamorize nicotine and tobacco product use. There is a critical need for ENDS regulation, legislative action, and counter promotion to protect youth. ENDS have the potential to addict a new generation of youth to nicotine and reverse more than 50 years of progress in tobacco control.

ObjectiveTo examine the impact of flavour, device type and health warning messages on youth preference for electronic nicotine delivery systems (ENDS), and to provide evidence and data to inform the Food and Drug Administration’s potential regulatory actions on ENDS.DesignAn online discrete choice experiment was conducted in September 2015. Each participant was given nine choice sets and asked to choose one out of two alternative ENDS products, with varying characteristics in three attributes (flavour, device type and warning message). The impact of the attributes on the probability of choosing ENDS was analysed using conditional and nested logit regressions, controlling for individual sociodemographic characteristics and current smoking status.Setting and participantsA general population sample of 515 participants (50 ever-users and 465 never-users of ENDS) aged 14–17 years were recruited to complete the experiment using an online panel.ResultsFruit/sweets/beverage flavours significantly increase the probability of choosing ENDS among youth (p<0.01 for never-users and <0.1 for ever-users) and flavour has the most pronounced impact among three attributes. Among never-users, menthol flavour also increases (p<0.05) the probability of choosing ENDS compared with tobacco flavour. Vaping devices that are modifiable, compared with cigarette-like e-cigarettes, increase (p<0.05) the probability of choosing ENDS among adolescent never-users. Warning messages reduce (p<0.01) the probability of choosing ENDS among never-users.Conclusions and relevanceRestricting fruit/sweets/beverage flavours in ENDS, regulating modifiable vaping devices and adopting strong health warning messages may reduce the uptake of ENDS among youth.
