Federal health officials have authorized sales of Vuse Alto, the best-selling e-cigarette in the U.S. The Food and Drug Administration made the decision Thursday, allowing Reynolds American to keep its reusable e-cigarette on the market for years to come. The authorization only applies to several tobacco-flavored versions of reusable product, which takes cartridges filled with liquid nicotine. The FDA previously rejected an application for Vuse's more popular menthol flavor. The FDA said smokers who completely switch to Vuse can reduce their exposure to deadly carcinogens found in cigarettes. The agency stressed that non-smokers should not use any vaping products, including Vuse.
