注意事项：我们比较了在4个国家购买的一种品牌的补充液中的尼古丁浓度，这些补充液标记为0 mg尼古丁/mL。然后，我们确定了来自这些国家的假冒电子烟产品。方法：总体而言，在尼日利亚，美国（US），英国和中国购买了125种电子烟填充液。使用高效液相色谱法测量尼古丁浓度，并与标记浓度进行比较。再填充液进行了检查，以确定物理差异，并分为正宗和假冒products.RESULTS：而尼古丁是在51.7%（15/29）的尼日利亚，3.7%（1/27）的中国和1.6%（1/61）的美国再填充液（范围= 0.4 - 20.4 mg/mL），8个英国产品不含尼古丁。来自中国、美国和尼日利亚的含有微量尼古丁的产品（0.4至0.6 mg/mL）是真实的;然而，来自尼日利亚的所有产品超过3.7 mg/mL都是假冒的。我们介绍了电子烟行业的两个新问题，生产假冒品牌的补充液，81.3%的假冒产品中含有尼古丁，标签为0 mg/mL。这项研究强调需要更好地控制和监测含尼古丁的产品和销售渠道。
OBJECTIVES: We compared nicotine concentrations in one brand of refill fluids that were purchased in 4 countries and labeled 0 mg of nicotine/mL. We then identified counterfeit e-cigarette products from these countries.METHODS: Overall, 125 e-cigarette refill fluids were purchased in Nigeria, the United States (US), England, and China. Nicotine concentrations were measured using high performance liquid chromatography and compared to labeled concentrations. Refill fluids were examined to identify physical differences and grouped into authentic and counterfeit products.RESULTS: Whereas nicotine was in 51.7% (15/29) of the Nigerian, 3.7% (1/27) of the Chinese and 1.6% (1/61) of the American refill fluids (range = 0.4 - 20.4 mg/mL), 8 British products did not contain nicotine. Products from China, the US, and Nigeria with trace amounts of nicotine (0.4 to 0.6 mg/mL) were authentic; however, all products from Nigeria with more than 3.7 mg/mL were counterfeit.CONCLUSIONS: We introduce 2 novel issues in the e-cigarette industry, the production of counterfeit refill fluids under a brandjacked label and inclusion of nicotine in 81.3% of the counterfeit products labeled 0 mg/mL. This study emphasizes the need for better control and monitoring of nicotine containing products and sales outlets.
