It is not certain whether or when the ban will end. This isn't the first time Chinese retailers have pulled e-cigs, but it's significantly wider than before. In September, Juul's e-cigarettes disappeared from the shelves just a week after they became available in China.
This will be a serious blow to e-cig manufacturers in China if it holds. The nation has over 300 million smokers of various kinds, and it can threaten both manufacturers and online stores that rely on e-cigar sales. It could hurt China as well, with state-owned China Tobacco producing nearly six percent of the country's tax revenue. It is not surprising that China will act. There are concerns around the world that e-cigarette companies are targeting teenagers, and it does not help with disease reports. China may be willing to sacrifice some of these tax dollars if it can prevent teenage use and health problems.
