Aug 29, 2018 12:31 AM CUT A new study found that about one in 20 American adults use e-cigarettes and that one in three users vape every day. Researchers report in the [_Annals of Internal Medicine_](http://annals.org/aim/article-abstract/2698112/prevalence-distribution-e-cigarette-use-among-u-s-adults-behavioral "undefined") that [e-cigarette use](http://time.com/5290019/e-cigarettes-research/ "undefined") is more common among younger adults and current cigarette smokers. [Reuters reports](https://www.yahoo.com/news/almost-1-20-u-adults-now-e-cigarettes-222114277.html "undefined") that of the 10.8 million people using e-cigarettes, more than half are under the age of 35. E-cigarette use is associated with high-risk behaviors, including the use of traditional cigarettes, one study author told Reuters. “The most common pattern of use in the U.S. is dual use, i.e. current use of both traditional cigarettes and electronic cigarettes,” Michael Blaha, a senior study author, said. Blaha said “vulnerable groups” are most susceptible to picking up an e-cigarette habit. According to the study, 14.4% of current smokers use e-cigarettes, while 1.4% of e-cigarette users never smoked traditional cigarettes. Vaping is also common among adults with chronic health issues, the study said. As more people vape, e-cigarettes are coming under more intense scrutiny. While the [health risks of e-cigarettes](http://time.com/5290019/e-cigarettes-research/ "undefined") are not totally clear, the chemicals in them are likely to pose some risks. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/5381078/american-e-cigarette-vape/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/5381078/american-e-cigarette-vape/"},"headline":"1 in 20 American Adults Are Using E-Cigarettes, New Study Finds","datePublished":"2018-08-29T00:31:33.000Z","dateModified":"2026-02-23T21:17:01.595Z","description":"Half the users are under 35","url":"https://time.com/5381078/american-e-cigarette-vape/","keywords":["health","onetime"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltdc5d268dad4d1734/698853e55f570fefdcb1be8f/e-cigarette.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Mahita Gajanan","jobTitle":"Gajanan is an editor at TIME.","url":"https://time.com/author/mahita-gajanan/"}],"articleSection":"U.S.","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltdc5d268dad4d1734/698853e55f570fefdcb1be8f/e-cigarette.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"New e-cigarette laws","caption":"New e-cigarette laws","creditText":"Yui Mok—AP","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/us/","name":"U.S."}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/health/","name":"health"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/5381078/american-e-cigarette-vape/","name":"1 in 20 American Adults Are Using E-Cigarettes, New Study Finds"}}]}] ```
