吸烟者使用电子烟的增加可能是导致许可尼古丁产品使用减少和/或非烟草含尼古丁产品总体使用增加的原因。本文报告了吸烟工具包研究（STS）的结果，该研究跟踪了电子烟和许可尼古丁产品的使用情况，以解决这一问题。数据来自2011年3月至2014年11月期间对英格兰14502名吸烟者的月度调查。 吸烟者被问及他们使用电子烟和许可的尼古丁产品。电子烟的使用率从2011年第2季度的2.2%（95%CI 1.4%至3.2%）迅速上升至2013年第3季度的20.8%（95%CI 18.3%至23.4%），之后没有变化。从2011年第2季度（17.4%，95% CI 15.3%至19.8%）至2013年第3季度（17.9%，95% CI 15.62%至20.5%），吸烟者中许可尼古丁产品使用的流行率保持稳定，此后稳步下降至7.9%（95% CI 6.0%至10.4%）。任何产品的使用率在2012年第1季度保持稳定，之后从18.5%（95% CI 16.3%至21.0%）增加至2013年第3季度的33.3%（95% CI 30.4%至36.3%），然后下降至22.7%（95% CI 19.3%至26.3%）。自2011年以来的轨迹形状表明，电子烟可能不是导致许可尼古丁产品使用下降的原因。电子烟似乎增加了非烟草含尼古丁产品的总市场。
The rise in electronic cigarette use by smokers may be responsible for the decreased use of licensed nicotine products and/or increased overall use of non-tobacco nicotine-containing products. This paper reports findings from the Smoking Toolkit Study (STS) tracking use of electronic cigarettes and licensed nicotine products to address this issue. Data were obtained from monthly surveys involving 14 502 cigarette smokers in England between March 2011 and November 2014. Smokers were asked about their use of electronic cigarettes and licensed nicotine products. Prevalence of electronic cigarette use increased rapidly from 2.2% (95% CI 1.4% to 3.2%) in quarter 2 of 2011 to 20.8% (95% CI 18.3% to 23.4%) in quarter 3 of 2013, after which there was no change. Prevalence of licensed nicotine product use in smokers remained stable from quarter 2 of 2011 (17.4%, 95% CI 15.3% to 19.8%) to quarter 3 of 2013 (17.9%, 95% CI 15.62% to 20.5%), and thereafter declined steadily to 7.9% (95% CI 6.0% to 10.4%). Prevalence of use of any product was stable to quarter 1 of 2012, after which it increased from 18.5% (95% CI 16.3% to 21.0%) to 33.3% (95% CI 30.4% to 36.3%) in quarter 3 of 2013, and then decreased to 22.7% (95% CI 19.3% to 26.3%). The shapes of trajectories since 2011 suggest that electronic cigarettes are probably not responsible for the decline in use of licensed nicotine products. Electronic cigarettes appear to have increased the total market for use of non-tobacco nicotine-containing products.
