The Food and Drug Administration is allowing vaping brand Juul to keep its e-cigarettes on the market, providing relief to a company that has struggled for years

FDA regulators said Thursday that Juul’s studies show its e-cigarettes are less harmful for adult smokers, who can benefit from switching completely to vaping.

The Food and Drug Administration authorized Juul e-cigarettes for the U.S. market on Thursday, ending a lengthy standoff with regulators and lawmakers who accused the company of spurring an epidemic of e-cigarette use among youths.
