Objective: We evaluated the potential population health impact of launching heated tobacco products (HTP) in Japan. Method: We use a modeling approach to project the effects of HTP use in overall mortality up to 2100 and compare those projections against a baseline scenario based on smoking rates pre-HTP launch, ie, smoking only. The model was informed using data from publicly available sources and the literature, including population size, yearly deaths, and smoking prevalence with the initial year of 2004, and births and migration from 2004 to 2065. Transitions between products were estimated from cross-sectional population surveys in Japan. Result: In a worst-case scenario, population health gains would be seen with HTPs risk about 50% lower risk than smoking. Assuming equal risk for dual use and smoking, HTP risk would need to be at least 10% lower than smoking to achieve a population health benefit by 2100. Potential reduction in life-years lost with the introduction of HTPs was 13 million by 2100 compared with smoking only. Conclusions: In credible scenarios, substantial population harm reduction will follow the introduction of HTPs in Japan. [ABSTRACT FROM AUTHOR]

Objectives: In this study, we examined whether visual exposure to the heated tobacco product (HTP) IQOS, which was authorized for sale by the US Food and Drug Administration in 2019, acts as a cue to increase cigarette craving and smoking behavior among smokers. Methods: Young adult smokers (N = 105) were randomly assigned to view a video depicting use of either IQOS or bottled water. Main outcomes were changes in cigarette and e-cigarette desire and latency to smoke between the groups. We also examined participants' attitudes about the actors using IQOS and drinking water in the videos. Results: Exposure to the use of IQOS acutely increased observers' ratings of smoking urge and desire for a cigarette and an e-cigarette. The IQOS cue, compared with the water cue, also produced a marginally significant shorter latency to smoke. Participants perceived actors as less likeable and friendly when using IQOS than when drinking water. Conclusions: Results showed that exposure to IQOS produced smoking urge and behavior in young adult smokers, implicating IqOs use as a smoking and vaping cue. As HTPs gain popularity, product impact on passive observers should be included in their risk-benefit profile. [ABSTRACT FROM AUTHOR]

Objectives: The US Food and Drug Administration (FDA) approved sales of heated tobacco products (HTPs) on April 30, 2019. In this paper, I provide a preliminary analysis of social media conversations regarding HTPs and the FDA authorization in the first 60 days. Methods: I examined 574 tweets regarding HTPs to assess tweet characteristics and semantic networks of HTPs. Results: Tweets were more likely to be neutral or anti-HTPs than pro-HTPs regardless of the author type (except for tobacco industry) or genre of the post. There was a small gap (6.4%) between the proportion of pro-HTPs and anti-HTPs among personal tweets. The proportion of pro-HTPs was larger in tweets posted by men (vs women and no sex specified) and from rural areas (vs urban). Nearly one-third of the sample mentioned cigarettes or e-cigarettes, even though the size of posts making claims on inferiority/superiority of HTPs was small. Conclusions: Social media conversations on risks of HTPs as well as surveillance on young consumer target marketing is occurring, and it will be important to assess the impact of tobacco companies' launch of HTP sales in the US to assess public perceptions on HTPs. Continuing surveillance of HTP marketing and risk perceptions will inform tobacco regulations. [ABSTRACT FROM AUTHOR]

Objectives: Heated tobacco products (such as IQOS) and e-cigarettes have been introduced and advertised in a variety of ways despite inconclusive evidence regarding their safety and benefit for smoking cessation. In this study, we examine the awareness, use, and perceived risk of these products among recent smokers. Methods: In 2017, we conducted an online survey of 727 current and recent smokers in Ontario. We asked participants about their awareness, use, and perceived risk of heated tobacco products and e-cigarettes. Results: Among respondents, 10% were aware of heated tobacco products, and 3% had ever used them. Compared to non-ecigarette users, e-cigarette users were more likely to agree with statements that heated tobacco is less harmful than regular cigarettes, e-cigarette use is less harmful than regular cigarettes, and both products can help smokers stop smoking regular cigarettes. Conclusions: Respondents who used e-cigarettes were more likely to have positive perceptions about heated tobacco and may be more susceptible to the marketing of these products. It is important to monitor the use of multiple nicotine products to inform policies and programming for these products. [ABSTRACT FROM AUTHOR]
