Impact of exposures to Heated Tobacco Products in the media and through social connections on product perceptions and use. Tob Prev Cessat 2024; 10:TPC-10-20. [PMID: 38738210 PMCID: PMC11082655 DOI: 10.18332/tpc/187246] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 04/16/2024] [Accepted: 04/16/2024] [Indexed: 05/14/2024]
Abstract
INTRODUCTION Little is known about media exposures to heated tobacco products (HTPs). In this study, we examined sources of HTP exposure, including from paid and unpaid media and social connections, in relation to HTP use and use intentions. METHODS In the fall of 2021, we conducted a cross-sectional survey among adult online panelists (aged 18-45 years) in the US and Israel, oversampling tobacco users. The current study analyzed data from participants who responded to the question about HTP awareness or use (n=2061). Multivariable linear and logistic regression analyses examined the relationship between sources of HTP exposure, HTP use, and use intentions. RESULTS Among those aware of HTPs, both Israelis and Americans reported past-month HTP media exposure via advertisements (58.2% vs 48.0%), non-advertisement sources (49.7% vs 30.7%), and social connections (51.5% vs 33.6%), respectively. Factors associated with HTP awareness (n=677/2061; 32.9%) included media use frequency (AOR=1.13; 95% CI: 1.01-1.28) and social connections using HTPs (AOR=2.45; 95% CI: 1.92-3.15). Among those aware of HTPs, past-month HTP exposure via digital media advertisements (AOR=2.06; 95% CI: 1.09-3.91) and non-advertising promotion via radio, podcast, movie, television or theatre (AOR=2.30; 95% CI: 1.19-4.44) and websites (AOR=2.36; 95% CI: 1.32-4.21) were associated with current HTP use. Exposure to digital media advertisements (β=0.35; 95% CI: 0.07-0.62) and non-advertising promotion via social media (β=0.62; 95% CI: 0.34-0.91) were correlated with higher use intentions. Having social connections using HTPs was correlated with higher use (AOR=2.21; 95% CI: 1.19-4.11) and intentions (β=0.66; 95% CI: 0.42-0.91). No significant differences were found across countries. CONCLUSIONS Digital media (e.g. online, social media) were particularly salient correlates of HTP intentions and use. Future studies are needed that further examine media exposures to these products, as well as that examine possible regulations to limit HTP promotion via these channels.

PMI's IQOS and cigarette ads in Israeli media: a content analysis across regulatory periods and target population subgroups. Tob Control 2024; 33:e54-e61. [PMID: 36418166 PMCID: PMC10203057 DOI: 10.1136/tc-2022-057671] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Accepted: 11/11/2022] [Indexed: 11/24/2022]
Abstract
BACKGROUND IQOS, manufactured by Philip Morris International (PMI), is the highest selling heated tobacco product globally. IQOS went through several regulatory changes in Israel: from no oversight to minimal tobacco legislation, to progressive legislation that included a partial advertisement ban (exempting print media) and plain packaging. We examined how PMI's advertising messages changed during these regulatory periods for both IQOS and cigarettes. METHODS Content analysis of PMI's IQOS and cigarette ads was performed using a predefined framework. Ad characteristics included regulatory period, target population, setting, product presentation, age and use restrictions, retail accessibility, additional detail cues (eg, QR code) and promotions. Ad themes included product features, legislation-related elements, social norms and comparative claims. Comparisons between IQOS and cigarette ads, and across regulatory periods, were examined using χ2 test or Fisher's exact test. RESULTS The dataset included 125 IQOS ads and 71 cigarette ads. IQOS ads featured more age restrictions, retail accessibility and additional detail cues, compared with cigarette ads (93.6% vs 16.9%; 56.0% vs 0.0%; and 95.2% vs 33.8%, p<0.001 for all). Cigarette ads featured mostly price promotions (52.1% vs 10.1% of IQOS ads, p<0.001). The main ad themes were technology for IQOS (85.6%) and quality for cigarettes (50.7%). In later (vs earlier) restrictive regulatory periods, IQOS ads featured more direct comparisons to cigarettes, QR codes and indoor settings, and did not feature product packaging. CONCLUSIONS IQOS advertisement content shifted as more restrictions went into effect, with several elements used to circumvent legislation. Findings from this study point to the necessity of a complete advertisement ban and ongoing marketing surveillance.

Tob Control 2023; 33:103-109. [PMID: 35680384 PMCID: PMC10804002 DOI: 10.1136/tobaccocontrol-2021-057081] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Accepted: 04/27/2022] [Indexed: 11/04/2022]
Abstract
The introduction of electronic inhalable products, such as nicotine vaping products (NVPs) and heated tobacco products (HTPs), has further diversified the nicotine market landscape. This poses unique challenges in measuring self-reported nicotine use behaviours, which have been the hallmark of tobacco surveillance systems. This paper raises concerns of potential measurement error for electronic inhalable product use in surveys due to similarities in product design between NVPs and HTPs, as well as changing trends in cannabis administration. We identify several strategies for addressing this issue (eg, including descriptive preambles in surveys that differentiate product classes from one another; incorporating survey questions that probe beyond an initial question regarding product use). In the absence of comprehensive validation studies, caution is warranted when interpreting survey results that rely on self-reported HTP use.

Abstract
We provide an extensive review of 17 independent and industry-funded studies targeting carbonyls in aerosol emissions of Heated Tobacco Products (HTPs), focusing on quality criteria based on the reproducibility of experiments, appropriate analytic methods, and puffing regimes. Most revised studies complied with these requirements, but some were unreproducible, while others failed to consider analytical variables that may have affected the results and/or produced unrealistic comparisons. We also provide a review of the literature on the physicochemical properties of heated tobacco and HTP aerosols, as well as the evaluation of HTPs by regulatory agencies, addressing various critiques of their relative safety profile. The outcomes from the revised studies and regulatory evaluations tend to agree with and converge to a general consensus that HTP aerosols expose users to significantly lower levels of toxicity than tobacco smoke.

IQOS Use and Interest by Sociodemographic and Tobacco Behavior Characteristics among Adults in the US and Israel. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:3141. [PMID: 36833831 PMCID: PMC9961058 DOI: 10.3390/ijerph20043141] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 02/04/2023] [Accepted: 02/06/2023] [Indexed: 06/18/2023]
Abstract
Heated tobacco products (HTPs) have expanded globally. IQOS, a global HTP leader, was launched in Israel in 2016 and the US in 2019. To inform tobacco control efforts, it is critical to understand who is likely to use HTPs in different countries with distinct regulatory and marketing contexts. Thus, we conducted a cross-sectional survey among adult (ages 18-45) online panelists in the US (n = 1128) and Israel (n = 1094), oversampling tobacco users, in the fall of 2021, and used multivariable regression to identify correlates of (1) ever using IQOS; (2) past-month vs. former among ever users; and (3) interest in trying IQOS among never users. Among US adults, correlates of ever use included being Asian (aOR = 3.30) or Hispanic (aOR = 2.83) vs. White, and past-month use of cigarettes (aOR = 3.32), e-cigarettes (aOR = 2.67), and other tobacco (aOR = 3.34); in Israel, correlates included being younger (aOR = 0.97), male (aOR = 1.64), and cigarette (aOR = 4.01), e-cigarette (aOR = 1.92) and other tobacco use (aOR = 1.63). Among never users, correlates of greater interest included cigarette and e-cigarette use in the US (β = 0.57, β = 0.90) and Israel (β = 0.88, β = 0.92). IQOS use prevalence was low (US: 3.0%; Israel: 16.2%) but represented in vulnerable subpopulations (younger adults, racial/ethnic minorities).

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:2016.

Abstract
Limited data exist on the awareness, beliefs, and use of heated tobacco products (HTPs). Data from 1583 U.S. adult (age ≥ 21 years) current tobacco users were collected in 2021. Participants self-reported HTP awareness, beliefs, use, and susceptibility, as well as current tobacco product use and sociodemographics. We used weighted logistic and multinomial regression models to explore their associations. Overall, 23.6% were aware of, 8.9% had ever used, and 3.0% currently used HTPs. Younger individuals (vs. 61+ years), those with annual income $50,000+ (vs. <$50,000), and those currently using electronic vaping products (vs. non-users) were more likely to be aware of, to have ever used, and to currently be using HTPs (p < 0.05). Black individuals (vs. White) were more likely to report ever and current HTP use (p < 0.05). Current cigarette smoking was not associated with HTP awareness and use (p > 0.05). Holding favorable HTP beliefs was associated with susceptibility to and more advanced HTP use statuses (p < 0.05). Sociodemographics associated with HTP use may reflect HTP marketing strategies. The lack of association with cigarette smoking suggests HTPs may be unlikely cigarette substitutes. Addressing favorable HTP-related beliefs may prevent dual use.

Abstract
The awareness of healthcare practitioners concerning heated tobacco product (HTP) use risks has been evaluated; however, few studies have investigated general dental practitioners’ awareness regarding HTP-use risks. In this cross-sectional study, we investigated dentists’ awareness of the risks of smoking, particularly HTP use. A self-administered questionnaire, including eight questions on conventional cigarette and HTP smoking/using status and both knowledge and awareness of HTP-use risks, was posted to 3883 dentists belonging to the Aichi Dental Association, Japan, in August 2019. Statistical analysis was performed using the Statistical Package for Social Sciences; statistical significance was set at p < 0.05. We analyzed the data of 1317 dentists (participation rate, 41.6%). The study group included cigarette smokers (11.5%) and HTP users (8.5%), among whom 41.1% were dual users. HTP users were more likely than never smokers/users to correctly perceive HTP-use risks (p < 0.05). This study indicates that in Japan, the proportion of HTP users is higher than that of the general population. It is important to educate not only smokers/users but also never smokers/users on the risks of smoking and using HTPs. Smoking cessation, including ceasing HTP use, and aiming to quit smoking and HTP use among dentists would contribute to appropriate smoking cessation among patients.

Abstract
Heated tobacco products (HTPs) are increasingly popular in Hong Kong (HK) even though they have not been formally launched and the sale of duty-not-paid tobacco sticks is illegal. We investigated how Facebook was used against regulations to sell HTPs in HK. We screened Facebook pages run by HTP businesses targeting HK users in June 2019 and included pages with over 300 "Likes" for inductive content analysis by coding their "About" descriptions and all posts including comments published since January 2017. HTPs included heating devices, accessories, and tobacco sticks. Various attributes were recorded including methods of customer inquiries (telephone, Instant Messaging [IM], address), business responses (comments or private messages, PM), and services provided (warranty/repair). Among 30 pages (50.9% of all 59 eligible pages with related information on HTPs), two-thirds provided phone numbers (66.7%), IM accounts (65.5%), and addresses (66.7%). Most pages sold heating devices (26, 86.7%) and accessories (22, 73.3%) with over 72% providing phone numbers, IM accounts, or addresses. Only 8 pages (26.7%) sold tobacco sticks with 75.0% providing telephone numbers but fewer provided IM accounts (62.5%) and addresses (50.0%). All pages responded using PMs and only 12.5% also used comments. Warranty/repair services were provided by 43.3% of the pages. We found Facebook pages were used as dedicated stores to promote and sell HTPs including heating devices, accessories, and even illicit tobacco sticks in HK, a non-official market.

Abstract
INTRODUCTION The growing use of heated tobacco products (HTPs) has raised concerns about secondhand aerosol (SHA) from HTPs, but few studies have been reported on it. This study aimed to investigate the trends in SHA exposure and their socioeconomic inequalities in Japan. METHODS The prevalence of SHA exposure from 2017 to 2020 was estimated using longitudinal internet survey data of 5221 participants, aged 20-69 years in 2017 (baseline), with adjustments using inverse probability weighting for "being a participant in an internet survey". Multivariable modified Poisson regression models were applied to examine the association between socioeconomic status (ie, educational attainment and equivalent income) at baseline and SHA exposure in 2020 with adjustments for sex and age. RESULTS The estimated prevalence of SHA exposure has consistently increased from 4.5% in 2017 to 10.8% in 2020. Lower educational attainment was associated with a higher risk of SHA exposure (p for trend = 0.010). The covariate-adjusted risks of SHA exposure in participants with a low-education and middle-education level were 1.57 and 1.34 times higher, respectively, than in those with a high-education level. However, significant differences in risks of SHA exposure between participants with low-, middle-, and high-income levels were not observed. Meanwhile, participants with a low-education and middle-education level also had 1.87 and 1.61 times higher risks of secondhand smoke (SHS) exposure from combustible cigarettes than those with a high-education level, respectively. CONCLUSIONS Our study revealed a rapid increase in SHA exposure and the existence of educational inequalities in both SHA and SHS exposure. IMPLICATIONS Using longitudinal internet cohort survey data, we found that the prevalence of exposure to secondhand aerosol (SHA) from heated tobacco products (HTPs) rapidly increased to 10.8% in 2020 in Japan. Furthermore, people with lower educational attainment were at higher risk of SHA exposure, suggesting that extensive educational interventions may be necessary to inform the public that although emissions from HTPs contain significantly lesser amounts of harmful and potentially harmful constituents and these compounds than cigarette smoke, they are not harmless and still entail risks, and its long-term effects are unknown. Therefore, future extensive monitoring of SHA exposure is needed.

Abstract
INTRODUCTION Despite the increased heated tobacco product (HTP) marketing in the United States, little is known about HTP perceptions and correlates of HTP use and use intentions among young adults. AIMS AND METHODS Using 2020 cross-sectional data from 2,470 young adults (ages 18-34) from 6 US metropolitan areas, we conducted exploratory factor analysis to identify factors regarding perceived utility/appeal of HTPs, specifically IQOS, and examined these factors in relation to lifetime HTP use and use intentions, using multivariable logistic and linear regression, respectively. RESULTS 19.1% had heard of HTPs and 4.1% ever used HTPs; 14.7% had heard of IQOS specifically and 2.8% were ever-users. Use intentions were low (M = 1.27, scale: 1 = not at all to 7 = extremely). Factor analysis identified five perceived utility/appeal factors: innovation (M = 3.17, scale: 1 = not at all to 7 = extremely), cigarette substitute (M = 2.99), and youth appeal (M = 2.82), e-cigarette/nicotine substitute (M = 2.36), and fashionable (M = 2.04). Controlling for sociodemographics and other tobacco use, perceiving IQOS as more fashionable and e-cigarette substitutes positively correlated with lifetime HTP use (aOR = 1.60, 95%CI = 1.17, 2.17; aOR = 1.48, 95%CI = 1.11, 1.97, respectively) and use intentions (β = 0.26, 95%CI = 0.21, 0.30; β = 0.14, 95%CI = 0.09, 0.18); perceiving IQOS as cigarette substitutes negatively correlated with ever use (aOR = 0.74, 95%CI = 0.56, 0.97) and use intentions (β = -0.06, 95%CI = -0.10, -0.03). Correlation patterns were similar among past-month cigarette, e-cigarette, and any-tobacco users. CONCLUSIONS Although HTP awareness and use were low, monitoring HTP perceptions and reasons for use as HTPs become more prominent is critical in anticipating their potential impact, particularly as more products seek FDA authorization to use reduced risk or exposure marketing claims. IMPLICATIONS Awareness, ever use, and intentions to use heated tobacco products (HTPs) were low among US young adults in 2020. Perceiving IQOS as fashionable and an e-cigarette substitute were positively correlated with ever use and intention to use HTPs. In addition, perceiving IQOS as a cigarette substitute was negatively correlated with ever use of HTPs and HTP use intentions. Continued surveillance on perceptions and use behaviors is needed to better understand use patterns, intentions to use, and reasons for using HTPs.

[PMID: 35380704 PMCID: PMC11062207 DOI: 10.1093/ntr/ntac065] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2021] [Revised: 03/02/2022] [Accepted: 03/09/2022] [Indexed: 11/13/2022]
Abstract
PURPOSE Heated tobacco products (HTP) heat-processed tobacco leaf into an aerosol inhaled by the user. This study assessed prevalence and correlates of HTP awareness, ever use, and current use among US middle and high school students. METHODS Data came from the 2019 and 2020 National Youth Tobacco Survey, a cross-sectional survey of US public and private, middle and high school students. HTP awareness, ever use, and current (past 30-day) use were assessed. Weighted prevalence estimates and adjusted prevalence ratios (aPR) were assessed overall and by sex, school level, race/ethnicity, and current other tobacco product use. RESULTS In 2019, 12.8% (3.44 million) of all students reported HTP awareness, increasing to 19.3% (5.29 million) in 2020 (p < .01). Ever [2019: 2.6% (630 000); 2020: 2.4% (620 000)] and current [2019: 1.6% (420 000); 2020: 1.4% (370 000)] HTP use did not significantly change from 2019 to 2020. Current e-cigarette users were more likely to report ever (2020 aPR = 1.79, 95% CI:1.23, 2.62) or current HTP use (2019 aPR = 5.16, 95% CI: 3.48, 7.67; 2020 aPR = 3.39, 95% CI: 2.10, 5.47) than nonusers. In both years, ever and current HTP use was more likely among current combustible (aPR range = 3.59-8.17) and smokeless tobacco product (aPR range = 2.99-4.09) users than nonusers. CONCLUSIONS HTP awareness increased 51% among US students during 2019-2020; however, HTP use did not significantly change during this period. Students who used other tobacco products were more likely to currently use HTPs. Estimates of HTP awareness and use provided serve as a baseline as future monitoring of these products is warranted. IMPLICATIONS Awareness of heated tobacco products (HTPs) increased among US youth from 2019 to 2020; however, HTP use did not change. These estimates of HTP awareness and use serve as a baseline for future surveillance of these products as their availability in the US increases.

Abstract
BACKGROUND Little is known about the use of novel heated tobacco products (HTPs) in low- and middle-income countries. We examined among smokers in Mexico the prevalence and correlates of HTP use, as well as reasons for using HTPs. METHODS We analyzed data from five surveys (November 2019-March 2021) of an open cohort of adult smokers (n = 6500), including an oversample of those who also use e-cigarettes. Mixed-effects multinomial logistic models were used to estimate associations between study variables and current HTP use or prior HTP trial relative to never trying HTPs. RESULTS The weighted prevalence of current HTP use was 1.1%. Independent correlates of current HTP use included smoking frequency, intention to quit, e-cigarette use, having partners/family-members who use e-cigarettes, friends who use HTPs, and exposure to HTP information inside/outside tobacco shops. Having partners/family members who smoke and not knowing about the harm of HTPs relative to cigarettes were associated with lower likelihood of current HTP use. Having tried HTPs was more likely among light daily smokers, those with family who use HTPs and exposure to HTP information outside shops and on newspapers/magazines. Among current users, the top reasons for using HTPs were greater social acceptability (50.6%) and lower perceived harm (34.9%) relative to cigarettes. CONCLUSIONS Uptake of HTPs appears relatively low among Mexican smokers, and correlates of use are similar to those for e-cigarette use. Further research is needed to determine if HTPs use promotes or impedes smoking cessation, given current HTP users are also likely to use various nicotine products.

Abstract
Tobacco, nicotine and related products have and continue to change rapidly, creating new challenges for policies regulating their advertising, promotion, sponsorship and sales. This paper reviews recent commercial product offerings and the regulatory challenges associated with them. This includes electronic nicotine delivery systems, electronic non-nicotine delivery systems, personal vaporisers, heated tobacco products, nicotine salts, tobacco-free nicotine products, other nicotine products resembling nicotine replacement therapies, and various vitamin and cannabis products that share delivery devices or marketing channels with tobacco products. There is substantial variation in the availability of these tobacco, nicotine, vaporised, and related products globally, and policies regulating these products also vary substantially between countries. Many of these products avoid regulation by exploiting loopholes in the definition of tobacco or nicotine products, or by occupying a regulatory grey area where authority is unclear. These challenges will increase as the tobacco industry continues to diversify its product portfolio, and weaponises 'tobacco harm reduction' rhetoric to undermine policies limiting marketing, promotion and taxation of tobacco, nicotine and related products. Tobacco control policy often lags behind the evolution of the industry, which may continue to sell these products for years while regulations are established, refined or enforced. Policies that anticipate commercial tobacco, nicotine and related product and marketing changes and that are broad enough to cover these product developments are needed.

Abstract
BACKGROUND The point-of-sale (POS) is adapting to marketing restrictions, societal changes and the inclusion of new products, such as heated tobacco products (eg, Philip Morris International's (PMI) IQOS device and HEETS sticks). We aimed to assess (1) PMI's influences on IQOS/HEETS POS marketing and (2) the implications of the new legislation (POS display ban and plain packaging) for retailers. METHODS A cross-sectional survey of 43 IQOS/HEETS POS owners/managers in five Israeli cities assessed POS and participant characteristics, marketing strategies, attitudes towards IQOS, and POS implications of the legislation and COVID-19, including industry reactions. Bivariate analysis explored differences between POS selling of the IQOS device versus POS selling of HEETS only. RESULTS A higher proportion of those carrying IQOS (n=15) (vs HEETS only) had special displays (100% vs 17.9%, p<0.001) and interacted with specific IQOS salespersons (73.3% vs 28.6%, p=0.013). Common promotions were financial incentives based on HEETS sales for retailers (37.5%) and price discounts on HEETS for customers (48.7%). Most indicated positive attitudes towards IQOS (72.1%; eg, 'less harmful'), opposition to the legislation (62.7%), limited government assistance to implement the legislation (62.8%), and industry provision of display cases and/or signage to comply with the legislation (67.4%). CONCLUSION PMI uses similar tactics to promote IQOS at POS as they previously used for combustible products, including direct promotional activities with retailers, and circumvented legislation by using special displays and signage. Governments need to ban these measures and support retailers with clear practical guidance regarding the implementation of marketing restrictions at POS.

Abstract
BACKGROUND Heated tobacco products (HTPs) are designed to heat tobacco to a high enough temperature to release aerosol, without burning it or producing smoke. They differ from e-cigarettes because they heat tobacco leaf/sheet rather than a liquid. Companies who make HTPs claim they produce fewer harmful chemicals than conventional cigarettes. Some people report stopping smoking cigarettes entirely by switching to using HTPs, so clinicians need to know whether they are effective for this purpose and relatively safe. Also, to regulate HTPs appropriately, policymakers should understand their impact on health and on cigarette smoking prevalence. OBJECTIVES To evaluate the effectiveness and safety of HTPs for smoking cessation and the impact of HTPs on smoking prevalence. SEARCH METHODS: We searched the Cochrane Tobacco Addiction Group's Specialised Register, CENTRAL, MEDLINE, and six other databases for relevant records to January 2021, together with reference-checking and contact with study authors and relevant groups. SELECTION CRITERIA We included randomised controlled trials (RCTs) in which people who smoked cigarettes were randomised to switch to exclusive HTP use or a control condition. Eligible outcomes were smoking cessation, adverse events, and selected biomarkers. RCTs conducted in clinic or in an ambulatory setting were deemed eligible when assessing safety, including those randomising participants to exclusively use HTPs, smoke cigarettes, or attempt abstinence from all tobacco. Time-series studies were also eligible for inclusion if they examined the population-level impact of heated tobacco on smoking prevalence or cigarette sales as an indirect measure. DATA COLLECTION AND ANALYSIS We followed standard Cochrane methods for screening and data extraction. Our primary outcome measures were abstinence from smoking at the longest follow-up point available, adverse events, serious adverse events, and changes in smoking prevalence or cigarette sales. Other outcomes included biomarkers of harm and exposure to toxicants/carcinogens (e.g. NNAL and carboxyhaemoglobin (COHb)). We used a random-effects Mantel-Haenszel model to calculate risk ratios (RR) with 95% confidence intervals (CIs) for dichotomous outcomes. For continuous outcomes, we calculated mean differences on the log-transformed scale (LMD) with 95% CIs. We pooled data across studies using meta-analysis where possible. MAIN RESULTS We included 13 completed studies, of which 11 were RCTs assessing safety (2666 participants) and two were time-series studies. We judged eight RCTs to be at unclear risk of bias and three at high risk. All RCTs were funded by tobacco companies. Median length of follow-up was 13 weeks. No studies reported smoking cessation outcomes. There was insufficient evidence for a difference in risk of adverse events between smokers randomised to switch to heated tobacco or continue smoking cigarettes, limited by imprecision and risk of bias (RR 1.03, 95% CI 0.92 to 1.15; I2 = 0%; 6 studies, 1713 participants). There was insufficient evidence to determine whether risk of serious adverse events differed between groups due to very serious imprecision and risk of bias (RR 0.79, 95% CI 0.33 to 1.94; I2 = 0%; 4 studies, 1472 participants). There was moderate-certainty evidence for lower NNAL and COHb at follow-up in heated tobacco than cigarette smoking groups, limited by risk of bias (NNAL: LMD -0.81, 95% CI -1.07 to -0.55; I2 = 92%; 10 studies, 1959 participants; COHb: LMD -0.74, 95% CI -0.92 to -0.52; I2 = 96%; 9 studies, 1807 participants). Evidence for additional biomarkers of exposure are reported in the main body of the review. There was insufficient evidence for a difference in risk of adverse events in smokers randomised to switch to heated tobacco or attempt abstinence from all tobacco, limited by risk of bias and imprecision (RR 1.12, 95% CI 0.86 to 1.46; I2 = 0%; 2 studies, 237 participants). Five studies reported that no serious adverse events occurred in either group (533 participants). There was moderate-certainty evidence, limited by risk of bias, that urine concentrations of NNAL at follow-up were higher in the heated tobacco use compared with abstinence group (LMD 0.50, 95% CI 0.34 to 0.66; I2 = 0%; 5 studies, 382 participants). In addition, there was very low-certainty evidence, limited by risk of bias, inconsistency, and imprecision, for higher COHb in the heated tobacco use compared with abstinence group for intention-to-treat analyses (LMD 0.69, 95% CI 0.07 to 1.31; 3 studies, 212 participants), but lower COHb in per-protocol analyses (LMD -0.32, 95% CI -1.04 to 0.39; 2 studies, 170 participants). Evidence concerning additional biomarkers is reported in the main body of the review. Data from two time-series studies showed that the rate of decline in cigarette sales accelerated following the introduction of heated tobacco to market in Japan. This evidence was of very low-certainty as there was risk of bias, including possible confounding, and cigarette sales are an indirect measure of smoking prevalence. AUTHORS' CONCLUSIONS No studies reported on cigarette smoking cessation, so the effectiveness of heated tobacco for this purpose remains uncertain. There was insufficient evidence for differences in risk of adverse or serious adverse events between people randomised to switch to heated tobacco, smoke cigarettes, or attempt tobacco abstinence in the short-term. There was moderate-certainty evidence that heated tobacco users have lower exposure to toxicants/carcinogens than cigarette smokers and very low- to moderate-certainty evidence of higher exposure than those attempting abstinence from all tobacco. Independently funded research on the effectiveness and safety of HTPs is needed. The rate of decline in cigarette sales accelerated after the introduction of heated tobacco to market in Japan but, as data were observational, it is possible other factors caused these changes. Moreover, falls in cigarette sales may not translate to declining smoking prevalence, and changes in Japan may not generalise elsewhere. To clarify the impact of rising heated tobacco use on smoking prevalence, there is a need for time-series studies that examine this association.

Abstract
INTRODUCTION Heated tobacco products, including Marlboro IQOS, are available globally. In the USA, IQOS was authorised to be advertised with claims about reduced toxicant exposure relative to cigarettes. The effects of such modified risk claims and health warnings have not been studied among young adult cigarette smokers and non-smokers. METHODS In 2020, US young adult (18-30 years, n=1328) cigarette smokers and non-smokers viewed an IQOS ad in a 4 (modified risk claim variations or none) by 3 (warning variations or none) between-subjects experiment. Outcome measures assessed perceived credibility and effectiveness of the health or risk message for discouraging IQOS use, perceived harms, efficacy beliefs, and IQOS use intentions. RESULTS Smokers reported significantly higher (p<0.05) perceived credibility, lower perceived effectiveness, higher efficacy beliefs about switching to IQOS and higher intentions to use IQOS than non-smokers. Among smokers, health warnings increased perceived credibility (p<0.001) and effectiveness (p<0.05), but claims did not affect outcomes examined. Among non-smokers, warnings and claims increased perceived credibility, and warnings increased perceived effectiveness (p<0.003). The reduced exposure claim increased non-smokers' intentions to use IQOS (b=0.40, 95% CI 0.07 to 0.73). CONCLUSIONS Among young adult smokers, health warnings increased perceived effectiveness at discouraging IQOS use and perceived credibility. Among non-smokers, warnings and claims increased perceived credibility and warnings increased perceived effectiveness, but the Food and Drug Administration-authorised reduced exposure claim increased intentions to use IQOS. Research is warranted to understand how the content of modified risk claims and health warnings for IQOS affects IQOS use in this population.

Abstract
Background: To gauge the public health impact of new nicotine products, information is needed on use among different populations. Aims were to assess in adults who smoked, vaped, did both or had recently stopped: (1) awareness, ever and current use of heated tobacco products (HTPs) and nicotine pouches (NP), (2) characteristics associated with ever use, (3) reasons for use of and satisfaction with HTPs, (4) characteristics associated with interest in use of HTPs. Methods: Online survey in the UK in 2019, n = 3883. (1) Proportion aware, ever and current (≥monthly) use; (2) ever use regressed onto socio-demographics and smoking/vaping; (3) frequency of reasons for HTP use and satisfaction; (4) interest in trying HTPs regressed onto socio-demographics and smoking/vaping status. Results: Awareness was 34.8% for HTP and 15.9% for NP; current use was 3.2% and 2.7%. Being <45 years, higher education, living in London and currently both smoking and vaping were associated with ever having used the products. Curiosity was the most common reason for HTP use (79.8%) and 72.0% of ever HTP users found them at least as satisfying as smoking. Among those not currently using HTPs, 48.5% expressed any interest-lower among those aged over 65 and higher among those smoking and vaping. Conclusions: In this sample of adults with a history of nicotine use, very few currently used heated tobacco products or nicotine pouches. Satisfaction with and interest in HTPs were substantial. The low level of use is unlikely to substantially reduce the public health impact of smoking.

Lempert LK, Bialous S, Glantz S. FDA's reduced exposure marketing order for IQOS: why it is not a reliable global model. Tob Control 2021; 31:e83-e87. [PMID: 33811155 PMCID: PMC8486889 DOI: 10.1136/tobaccocontrol-2020-056316] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Revised: 01/20/2021] [Accepted: 02/02/2021] [Indexed: 12/24/2022]
Abstract
The US Food and Drug Administration (FDA) issued orders in July 2020 authorising Philip Morris Products S.A. to market its heated tobacco product (HTP) IQOS inside the USA with claims that it reduces exposure to some dangerous substances. FDA's 'reduced-exposure' orders explicitly prohibit the marketing of IQOS with claims that IQOS will reduce harm or the risk of tobacco-related diseases. Under US law, FDA's IQOS orders are problematic because FDA disregarded valid scientific evidence that IQOS increases exposure to other dangerous toxins and that Philip Morris Products S.A. failed to demonstrate that consumers understand the difference between reduced-exposure and reduced-harm claims. Unfortunately, both 'reduced-exposure' and 'reduced-harm' are classified as 'modified risk tobacco products' under US law. Exploiting this confusion, Philip Morris International used the FDA decision as the basis for marketing and public relations campaigns outside the USA to press governments to reverse policies that ban or regulate the sales and marketing of HTPs, including IQOS. Parties to the WHO Framework Convention on Tobacco Control should reject tobacco companies' unsubstantiated explicit or implied claims of reduced harm associated with HTPs and resist Philip Morris International's and other companies' calls to relax HTP regulations based on the FDA's actions. Instead, parties should adopt policies aligned with the Framework Convention on Tobacco Control when dealing with HTPs and other novel tobacco products.
