To examine the impact of US restrictions implemented in February 2020 prohibiting flavors other than menthol and tobacco in cartridge-based e-cigarettes. We analyzed 5 cross-sectional waves of the International Tobacco Control Policy Evaluation Project Youth Tobacco and Vaping Surveys, conducted online with youths aged 16 to 19 years in the United States, Canada, and England, for differences in usual e-cigarette flavor, device, and brand reported by past-30-day vapers (n = 9512) before (2017, 2018, 2019), during (February 2020), and after (August 2020) implementation of US flavor restrictions. In August 2020, 78.7% of vapers in the United States reported using a flavor prohibited in cartridges or pods, versus 86.3% in Canada (adjusted odds ratio [AOR] = 1.73; 95% CI = 1.25, 1.40) and 79.8% in England (AOR = 1.10; 95% CI = 0.78, 1.55). Disposable e-cigarettes (exempt from flavor restrictions) increased to a greater extent among vapers in the United States (13.2% to 36.8%) versus Canada (7.7% to 14.2%; AOR = 2.01; 95% CI = 1.33, 3.04) and England (10.8% to 16.4%; AOR = 2.33; 95% CI = 1.52, 3.57). Puff Bar (disposable) emerged as the most popular brand in the United States. Usual flavors used by youth vapers in the United States were unchanged after 2020 restrictions on cartridge-based e-cigarettes. Youths used brands and devices exempt from the restrictions.

为了研究 2020 年 2 月美国实施的限制除薄荷醇和烟草以外的口味在墨盒式电子烟中使用的规定的影响。我们分析了国际烟草控制政策评估项目青年烟草和蒸气调查的 5 个横断面波次，该调查在美国、加拿大和英国进行了在线调查，调查对象为 16 至 19 岁的青少年，询问他们在过去 30 天内使用过的电子烟的通常口味、装置和品牌电子烟的使用情况，包括在 2017 年、2018 年、2019 年（实施前）、2020 年 2 月（实施期间）和 2020 年 8 月（实施后）使用过的电子烟。2020 年 8 月，美国 78.7%的电子烟使用者报告使用了墨盒或烟弹中禁止的口味，而加拿大为 86.3%（调整后的优势比[OR]为 1.73；95%CI 为 1.25，1.40），英国为 79.8%（OR 为 1.10；95%CI 为 0.78，1.55）。在美国，一次性电子烟（不受口味限制）的使用比例增加了（从 13.2%增加到 36.8%），而加拿大的电子烟使用比例仅增加了（从 7.7%增加到 14.2%；OR 为 2.01；95%CI 为 1.33，3.04），英国增加了（从 10.8%增加到 16.4%；OR 为 2.33；95%CI 为 1.52，3.57）。一次性电子烟棒（Puff Bar）在美国成为最受欢迎的品牌。2020 年限制墨盒式电子烟后，美国青少年电子烟使用者的常用口味没有改变。青少年使用的品牌和设备不受限制。（《美国公共卫生杂志》2022 年 112 卷第 7 期 1014-1024 页）。
