A new study suggests that is the case, finding that adolescents who use e-cigarettes are over three times more likely to use cannabis than those who don’t — and that more than 1 in 10 youths who say they have never used cannabis go on to do so within a year.

Between 2017 and 2019, they found, those who reported vaping were more likely to say they had begun using cannabis one year later than those who didn’t use e-cigarettes. The researchers ruled out factors such as socioeconomic status and other substance use.

Of the adolescents who hadn’t used cannabis at the beginning of the study, nearly 11 percent used cannabis in the following year, even those who had never used tobacco. But those who said they had smoked e-cigarettes were far more likely to move on to cannabis. E-cigarette users were 3.2 times more likely to use cannabis and 2.9 percent more likely to say they had used it within the past month. [Read More @ The Washington Post]
