| description | Providing data on usage patterns is key to assessing the reduced-risk potential of novel tobacco and nicotine products as compared to conventional cigarettes at a population level. A pilot cross-sectional survey was conducted in 2018 across 3 areas of Japan (Tokyo, Osaka, and Sendai) to assess tobacco and nicotine product use after the introduction of Heated Tobacco Products (HTPs). Following successful completion of the pilot study, two nationwide cross-sectional surveys were conducted using the general population in Japan to assess use patterns after the introduction of HTPs. The first (Wave 1) was conducted in 2019, and the second in 2020. In Wave 2, the concern of this publication, additional population-level data was obtained on use patterns and behaviour relating to tobacco and nicotine products in Japan. Eligible participants were Japanese residents, aged 20 years or older who consented to complete the survey. A 3-stage probability sampling method was applied that was geographically stratified by street blocks proportionate to population density. Respondents self-reported patterns of product use and reasons for HTP use. Complete responses were available from 5307 individuals, of whom 889 (16.7%) were current users, 1012 (19.1%) were former users, and 3407 (64.2%) were never users of tobacco products (weighted respondent totals). Of current tobacco users, 63.5% smoked cigarettes exclusively and 17.9% used HTPs exclusively. HTP dual use in combination with conventional cigarettes was 12.7%. The remaining 5.9% of users were categorised as poly users (i.e., use of 2 or more tobacco products). The most common reasons reported for HTP use were perceived reduction in harm to others and self - compared to cigarettes. These findings are consistent across pilot and Wave 1 conducted in Japan as part of this survey programme. Cigarettes were still the most frequent tobacco product used (13.4% in the pilot to 15.5% in Wave 1) within the general population, the usage prevalence for HTPs (5.3% to 5.4%) being considerable in comparison to other tobacco or nicotine-containing products like cigars, cigarillos, pipe, kiseru, and oral tobacco, where usage prevalence was close to zero. As with the previous Waves, no gateway effect (use of non-traditional combustible tobacco use – such as e-cigarettes and in this case HTP use – leading to subsequent tobacco smoking) was observed in this study. |
