Special Issue Information

Dear Colleague,

This Special Issue will focus on the public health implications of heated tobacco products (HTP) – also known as heat-not-burn products. Recent examples of HTPs marketed globally include IQOS (PMI), Glo (BAT), and TECH (JTI). Like other non-combustible nicotine devices, HTPs may produce lower levels of toxic emissions compared with combusted cigarettes, leading to lowered exposure in consumers who switch completely. Nonetheless, there are concerns about the broader public health implications of HTPs, including changes in perception of smoking risk, delay in smoking cessation, dual use with combusted cigarettes, and initiation of tobacco use among youth.

Therefore, a rigorous evidence base is needed to inform the public health community and guide regulatory strategies to ensure that HTPs support tobacco harm reduction objectives. A comprehensive approach to FTP regulation will be founded on cutting-edge science across a range of research topics and disciplines. We invite papers on HTPs that include research on the following: product design analysis; chemical testing (tobacco and smoke analysis); preclinical human testing (perceptions, use behavior, exposure biomarkers); human trials and epidemiological analysis; analysis of advertising, marketing, and health warnings; tax policy; and post-market surveillance. We are also interested in the weight of scientific evidence reviews, and we welcome papers from diverse global settings. By highlighting emerging research on HTPs from leading public health scientists and policy experts, this Special Issue will provide critical evidence to advance tobacco harm reduction and public health policy.

South Korea is the world’s second-largest heated tobacco product (HTP) market after Japan. HTP sales in South Korea have increased rapidly since May 2017, accounting for 10.6% of the total tobacco market in 2020. Despite this, little is known as to why HTP consumers who were current and former smokers started using HTPs and used them regularly. We analyzed cross-sectional data for 1815 adults (aged 19+) who participated in the 2020 International Tobacco Control (ITC) Korea Survey, of whom 1650 were HTP-cigarette consumers (those who reported smoking cigarettes and using HTPs ≥ weekly) and 165 were exclusive HTP consumers (using HTPs ≥ weekly) who were former or occasional smokers (smoking cigarette < weekly). Respondents were asked to report the reason(s) they used HTPs, with 25 possible reasons for HTP-cigarette consumers and 22 for exclusive HTP consumers. The most common reasons for initiating HTP use among all HTP consumers were out of curiosity (58.9%), family and friends use HTPs (45.5%), and they like the HTP technology (35.9%). The most common reasons for regularly using HTPs among all HTP consumers were that they were less smelly than cigarettes (71.3%), HTPs are less harmful to own health than cigarettes (48.6%), and stress reduction (47.4%). Overall, 35.4% of HTP-cigarette consumers reported using HTPs to quit smoking, 14.7% to reduce smoking but not to quit, and 49.7% for other reasons besides quitting or reducing smoking. In conclusion, several common reasons for initiating and regularly using HTPs were endorsed by all HTP consumers who were smoking, had quit smoking completely, or occasionally smoked. Notably, only about one-third of HTP-cigarette consumers said they were using HTPs to quit smoking, suggesting that most had no intention of using HTPs as an aid to quit smoking in South Korea.

Markets for nicotine vaping products (NVPs) and heated tobacco products (HTPs) have grown as these products became positioned as harm-reduction alternatives to combusted tobacco products. Herein, we present a public health decision-theoretic framework incorporating different patterns of HTP, NVP, and cigarette use to examine their impacts on population health. Our framework demonstrates that, for individuals who would have otherwise smoked, HTP use may provide public health benefits by enabling cessation or by discouraging smoking initiation and relapse. However, the benefits are reduced if more harmful HTP use replaces less harmful NVP use. HTP use may also negatively impact public health by encouraging smoking by otherwise non-smokers or by encouraging initiation or relapse into smoking. These patterns are directly influenced by industry behavior as well as public policy towards HTPs, NVPs, and cigarettes. While substantial research has been devoted to NVPs, much less is known about HTPs. Better information is needed to more precisely define the health risks of HTPs compared to cigarettes and NVPs, the relative appeal of HTPs to consumers, and the likelihood of later transitioning to smoking or quitting all products. While our analysis provides a framework for gaining that information, it also illustrates the complexities in distinguishing key factors. Full article

IQOS, the leading heated tobacco product globally, recently received ‘reduced exposure’ authorization from the US Food and Drug Administration. Independent research focusing on IQOS marketing and potential impact on consumers’ perceptions and behavior, and ultimately public health, is critical. The literature to date has underscored several concerns. First, Philip Morris’s (PM’s) marketing distribution requires scrutiny, particularly given its innovative promotional strategies. For example, IQOS is distributed via unique points-of-sale (POS; e.g., specialty and pop-up stores, “corners” in convenience stores) and uses various other opportunities (e.g., social media, sponsored events, direct-to-consumer). Second, although PM claims that IQOS’ target market is current combustible tobacco users and not young people, the literature indicates that in some populations, IQOS use is equally prominent among smokers and nonsmokers, and that specific subgroups (e.g., young adults, women) are targeted. Third, the impact of IQOS’ use of ad content promoting IQOS health benefits must be studied (e.g., how consumers interpret modified exposure messages). In conclusion, surveillance of IQOS marketing, particularly following reduced exposure authorization, is critical for obtaining valuable data to estimate population impact, particularly among population subgroups (e.g., young adults), and inform future tobacco regulation. These considerations have implications beyond IQOS—to other products and companies. Full article
