WASHINGTON (AP) — For the first time, U.S. heath officials have authorized an electronic cigarette, saying the vaping device from R.J. Reynolds can benefit smokers. The Food and Drug Administration said data submitted by the company showed its Vuse Solo e-cigarette helped smokers significantly cut back their use of cigarettes. Tuesday’s action is part of a sweeping effort by the FDA to bring scientific scrutiny to the multibillion-dollar vaping industry after years of regulatory delays. In September, the agency rejected applications for more than a million e-cigarettes and related products, mainly due to their potential appeal to underage teens.
