This study examines the association of Federal Canadian regulations passed in 2009 addressing flavours (excluding menthol) in small cigars with changes in cigar sales.
Quarterly wholesale unit data as reported to Health Canada from 2001 through 2016 were analysed using interrupted time series analysis. Changes in sales of cigars with and without flavour descriptors were estimated. Analyses were seasonally adjusted. Changes in the flavour types were assessed over time.
The Federal flavour regulations were associated with a reduction in the sales of flavoured cigars by 59 million units (95% CI -86.0 to -32.4). Increases in sales of cigars with descriptors other than flavours (eg, colour or other ambiguous terms) were observed (9.6 million increase (95% CI -1.3 to 20.5), but the overall level (decline of 49.6 million units (95% CI -73.5 to -25.8) and trend of sales of cigars (6.9 million units per quarter (95% CI -8.1 to -5.7)) declined following the ban. Sensitivity analysis showed that there was no substantial difference in effect over time comparing Ontario and British Columbia, suggesting that other provincial tobacco control legislation was not associated with the changes in levels. Analyses suggested that the level change was sensitive to the specification of the date.
This study demonstrates that flavour regulations have the potential to substantially impact tobacco sales. However, exemptions for certain flavours and product types may have reduced the effectiveness of the ban, indicating the need for comprehensive, well-designed regulations.
本研究考察了加拿大联邦政府于 2009 年通过的针对小雪茄口味（不包括薄荷醇）的法规与雪茄销售变化之间的关联。
使用季节性调整的中断时间序列分析方法，分析了 2001 年至 2016 年向加拿大卫生部报告的每季度批发单位数据。估计了有和没有口味描述符的雪茄销售变化。分析了随时间变化的口味类型变化。
联邦口味法规与调味雪茄销售量减少 5900 万支（95%CI-860 至-324）相关。观察到除口味（例如，颜色或其他模糊术语）以外的描述符的雪茄销售量增加（增加 960 万支（95%CI-13 至 205），但总体水平（下降 4960 万支（95%CI-735 至-258）和雪茄销售趋势（每季度增加 690 万支（95%CI-8.1 至-5.7））在禁令后下降。敏感性分析表明，安大略省和不列颠哥伦比亚省之间的效果随时间没有实质性差异，表明其他省级烟草控制立法与水平变化无关。分析表明，水平变化对日期的规范敏感。
本研究表明，口味法规有可能对烟草销售产生重大影响。然而，某些口味和产品类型的豁免可能降低了禁令的有效性，表明需要全面、精心设计的法规。
