Banning e-cigarette use in public places has attracted considerable debate, with governments adopting different policies. However, little is known about the outcomes of such bans. We investigated the association of banning e-cigarette use in public places and workplaces in Canadian provinces with adults' vaping and smoking behaviours.
Difference-in-differences.
Nationally representative Canadian Tobacco Use Monitoring Survey (CTUMS) and Canadian Tobacco, Alcohol and Drugs Survey (CTADS).
Adults aged 19 and older from CTADS 2013-2017 for e-cigarette outcomes (N=36 562) and from CTUMS/CTADS 2004-2017 for combustible cigarette outcomes (N=178 654).
Bans on e-cigarette use in public places and workplaces in Canadian provinces.
Past 30-day e-cigarette use, current combustible cigarette use, use of e-cigarettes when unable to smoke combustible cigarettes.
After the bans, e-cigarette use in the past 30 days did not change significantly in provinces with a ban compared with provinces without a ban (0.004; 95% CI -0.025 to 0.032; p=0.783). The bans also had no impact on current combustible cigarette use (0.009; 95% CI -0.019 to 0.037; p=0.488). There is evidence of ban evasion among young people aged 19-24 who, after the bans, reported higher use of e-cigarettes when unable to smoke combustible cigarettes (0.114; 95% CI -0.023 to 0.250; p=0.092).
Two years after implementation, the aerosol-free laws in Canada had no impacton adults' vaping and smoking behaviours. Policy efforts are urgently needed to improve the ban enforcement and to deal with discreet vaping among young adults.
公共场所禁止电子烟使用引起了广泛的争论，各国政府采取了不同的政策。然而，对于这些禁令的结果知之甚少。我们调查了加拿大各省公共场所和工作场所禁止使用电子烟与成年人吸烟和电子烟使用行为之间的关系。
差异中的差异。
具有全国代表性的加拿大烟草使用监测调查（CTUMS）和加拿大烟草、酒精和毒品调查（CTADS）。
来自 CTADS 2013-2017 年电子烟结果的年龄在 19 岁及以上的成年人（N=36562）和来自 CTUMS/CTADS 2004-2017 年可燃香烟结果的成年人（N=178654）。
加拿大各省公共场所和工作场所禁止使用电子烟。
过去 30 天电子烟使用、当前可燃香烟使用、无法使用可燃香烟时使用电子烟。
在禁令实施后，与没有禁令的省份相比，有禁令的省份过去 30 天电子烟使用量没有显著变化（0.004；95%CI-0.025 至 0.032；p=0.783）。禁令对当前可燃香烟使用也没有影响（0.009；95%CI-0.019 至 0.037；p=0.488）。19-24 岁的年轻人有规避禁令的证据，在禁令实施后，他们报告在无法使用可燃香烟时更频繁地使用电子烟（0.114；95%CI-0.023 至 0.250；p=0.092）。
在实施两年后，加拿大的无气溶胶法律对成年人的吸烟和电子烟使用行为没有影响。迫切需要政策努力来加强禁令执行，并解决年轻成年人 discreet vaping 问题。
