Vaping doesn’t often help smokers quit, new study finds

Makers of electronic cigarettes and other vaping devices often tout their products as smoking cessation aids. But new research suggests that the devices haven’t helped many U.S. smokers quit.

In a study published Monday in the journal PLOS One, researchers at Georgia State University found that U.S. adult smokers who didn’t use electronic vaping devices were more than twice as likely to quit as those who did.
