This study used over-the-counter (OTC) sales of nicotine replacement therapy (NRT) to investigate the impact of the introduction of smoke-free legislation in Scotland in March 2006 on smoking cessation behaviour. The time series of NRT sales (units and value) in Scotland from 2004 to 2006 were compared with the same period for the rest of the UK, and analysed using an ARIMA time series model. There was a significant increase in units and value of NRT sales in Scotland in the first 6 months of 2006 (p< or =0.001), apparent from January and prior to the introduction of the smoking ban, with no comparable increase for the rest of the UK. There was no significant increase in NRT sales for the second half of 2006. These data suggest an increase in smoking cessation behaviour in the period immediately before the introduction of smoke-free legislation, but this was not sustained beyond the first few months of the post-legislation period.
本研究利用非处方（OTC）尼古丁替代疗法（NRT）的销售情况，来调查2006年3月苏格兰实施无烟立法对戒烟行为的影响。将2004年至2006年苏格兰NRT的销售时间序列（单位和价值）与英国其他地区同期数据进行比较，并使用自回归积分滑动平均（ARIMA）时间序列模型进行分析。2006年上半年，苏格兰NRT的销售单位和价值显著增加（p≤0.001），这一增长从1月开始且在禁烟令实施之前就已显现，而英国其他地区则没有类似增长。2006年下半年，NRT的销售额没有显著增加。这些数据表明，在无烟立法实施前的一段时间内，戒烟行为有所增加，但在立法后的头几个月之后，这种增加并未持续。
