Transcript for New study shows link between teens, vaping and marijuana

Reporter: Good morning, this study finding e-cigarettes may be a potential gateway for on Monday researchers at Boston's children hospital releasing their analysis of 21 studies finding that teens and young adults who used vapes were nearly three and a half times more likely to use marijuana. For those e-cigarette users in middle school and high school, that numbers gets even higher. As David mentioned, that 12 to 17 age group four times more likely to go on and use marijuana. But the long term effects is still relatively unknown. Researchers tell us with conventional cigarettes it took 20, 30, 50 years to fully understand the effects, so we've got another 10 years or so before we can really look at what's happening here.
