Vaping Companies Sue to Delay US E-Cigarette Review Associated Press A vaping industry group sued the U.S. government on Wednesday to delay an upcoming review of thousands of e-cigarettes on the market. The legal challenge by the Vapor Technology Association is the latest hurdle in the Food and Drug Administration's yearslong effort to regulate the multibillion-dollar vaping industry, which includes makers and retailers of e-cigarette devices and flavored solutions. The vaping group argued that the latest deadline of next May to submit products for review could wipe out many of the smaller companies. The lawsuit was filed in U.S. District Court in Kentucky. E-cigarettes first appeared in the U.S. more than a decade ago and have grown in popularity despite little research on their long-term effects, including whether they can help smokers quit cigarettes. .
