E-cigarette sales in recent weeks grew by the slowest rate in more than a year and a half amid public health warnings over vaping, while cigarette sales declines eased slightly in the past month, according to industry data.

Sales of e-cigarettes grew by 25.5% in the four weeks ended Oct. 5 compared with the same period a year ago, Cowen analyst Vivien Azer wrote, citing data from Nielsen. It’s a significant slowdown from the monthly growth rates of more than 50% that the e-cigarette category has seen since at least August 2018.
