Some jurisdictions have passed legislation that bans electronic cigarette (e-cig) use (vaping) in public places similarly to smoking. Many other jurisdictions have not yet determined how to regulate vaping in public places. This study examined the proportion of current e-cig users who find their vaping restricted in public places and further evaluated factors associated with the differences between restricted and unrestricted vapers.
3960 experienced exclusive e-cig users completed an online survey from December 2012 to May 2014 about their e-cig use. Restricted vapers were defined as those who reported not being able to vape in places where smoking is typically banned. Unrestricted vapers were defined as those who reported being able vape in places where smoking is typically banned. χ and two-sided t-tests were used as appropriate to determine differences between variables of interest.
Participants were a mean age of 40.3 years, 72.0% male, 91.8% white and 85.1% were from the USA. 26.1% (n=1034) of users reported restricted vaping, while 73.9% (n=2926) reported unrestricted vaping. Restricted vapers used less frequently (p<0.001) and were less dependent compared with unrestricted vapers (p=0.001). Of the restricted vapers, only 12% (n=124) reported finding it difficult to refrain from vaping in places where they were not supposed to. These users were more dependent (p<0.001) and more likely to experience strong cravings (p<0.001), compared with users who did not find it difficult to refrain from vaping.
This study found that most vapers report unrestricted use of their e-cig. Of the restricted vapers, the majority (88%) do not find it difficult to refrain from vaping in places where they are not supposed to vape.
一些司法管辖区已通过立法，像禁止吸烟一样在公共场所禁止使用电子烟（吸电子烟）。许多其他司法管辖区尚未确定如何对公共场所吸电子烟进行监管。本研究调查了当前电子烟使用者中发现其在公共场所吸电子烟受到限制的比例，并进一步评估了与受限制和不受限制的吸电子烟者之间差异相关的因素。
2012年12月至2014年5月，3960名有经验的纯电子烟使用者完成了一项关于其电子烟使用情况的在线调查。受限制的吸电子烟者被定义为那些报告在通常禁止吸烟的场所无法吸电子烟的人。不受限制的吸电子烟者被定义为那些报告在通常禁止吸烟的场所能够吸电子烟的人。根据情况使用χ检验和双侧t检验来确定感兴趣变量之间的差异。
参与者的平均年龄为40.3岁，72.0%为男性，91.8%为白人，85.1%来自美国。26.1%（n = 1034）的使用者报告吸电子烟受到限制，而73.9%（n = 2926）报告不受限制。与不受限制的吸电子烟者相比，受限制的吸电子烟者使用频率较低（p < 0.001）且依赖性较小（p = 0.001）。在受限制的吸电子烟者中，只有12%（n = 124）报告发现在不应该吸电子烟的场所难以克制不吸。与那些发现在不应该吸电子烟的场所不难克制不吸的使用者相比，这些使用者依赖性更强（p < 0.001）且更有可能经历强烈的渴望（p < 0.001）。
本研究发现，大多数吸电子烟者报告其电子烟使用不受限制。在受限制的吸电子烟者中，大多数（88%）发现在不应该吸电子烟的场所不难克制不吸。
