Abstract：
BACKGROUND: Many people continue to smoke despite strong policies to deter use, thus stronger regulatory measures may be required. In four high-income countries, we examined whether people who smoke would support a total ban on smoked tobacco products under two differing policy scenarios.
METHODS: Data were from 14 363 adults (≥18) who smoked cigarettes (≥monthly) and participated in at least one of the 2018, 2020 or 2022 International Tobacco Control Four Country Smoking and Vaping Surveys in Australia, Canada, England and the USA. In 2018, respondents were asked whether they would support a law that totally bans smoked tobacco if the government provides smoking cessation assistance (Cessation Assistance scenario). In 2020 and 2022, respondents were asked a slightly different question as to whether they would support a law that totally bans smoked tobacco if the government encourages people who smoke to use alternative nicotine products like vaping products and nicotine replacement products instead (substitution scenario). Responses (support vs oppose/don\'t know) were estimated on weighted data.
RESULTS: Support was greater for the cessation assistance scenario (2018, 36.6%) than the nicotine substitution scenario (2020, 26.9%; 2022, 26.3%, both p<0.0001). In the longitudinal analysis, there was a significant scenario by country interaction effect with lower support in Canada, the USA and Australia under the substitution scenario than in the cessation scenario, but equivalent levels in England under both scenarios. The strongest correlates of support under both scenarios were planning to quit smoking within 6 months, wanting to quit smoking \'a lot\' and recent use of nicotine replacement therapy.
CONCLUSIONS: Opposition to banning smoked tobacco predominates among people who smoke, but less with a cessation assistance scenario than one encouraging nicotine substitution. Wanting to quit a lot was the strongest indicator of support.

摘要：
背景：许多人继续吸烟，尽管有强有力的政策来阻止使用，因此，可能需要采取更强有力的监管措施。在四个高收入国家，我们研究了在两种不同的政策情景下，吸烟的人是否会支持全面禁止烟熏烟草制品。
方法：数据来自14363名成年人（≥18岁），他们吸烟（≥每月一次），并参加了至少一项2018年，2020年或2022年国际烟草控制四国吸烟和吸烟调查。加拿大,英国和美国。2018年，受访者被问及如果政府提供戒烟援助，他们是否会支持一项完全禁止吸烟的法律(戒烟援助方案)。在2020年和2022年，受访者被问到一个略有不同的问题，即如果政府鼓励吸烟者使用替代尼古丁产品，如vaping产品和尼古丁替代产品（替代方案），他们是否会支持完全禁止吸烟的法律。响应(支持与反对/不知道)是在加权数据上估计的。
结果：戒烟援助方案（2018年，36.6%）的支持率高于尼古丁替代方案（2020年，26.9%；2022年，26.3%，两者p<0.0001)。在纵向分析中，在加拿大，国家互动效应存在一个显著的情景，支持度较低，美国和澳大利亚在替代情景下比在停止情景下，但在这两种情况下，英格兰的水平相当。在这两种情况下，最强烈的支持是计划在6个月内戒烟，想要戒烟\“很多\”和最近使用尼古丁替代疗法。
结论：反对禁止吸烟的人占主导地位，但戒烟援助方案少于鼓励尼古丁替代方案。想要退出很多是最有力的支持指标。
