People under 20 who used vapes were more than three times as likely to have ever smoked tobacco cigarettes, and more than twice as likely to have smoked cigarettes in the previous month, according to a review of 25 studies globally.
Serene Yoong, an associate professor at Swinburne University of Technology in Melbourne and the study’s lead author, said the findings pointed to the need for youth prevention programs and better regulation of e-cigarette products.
“Every single study showed an association between [e-cigarette] use among non-smokers and increased use of cigarettes at follow-up,” she said.
