Young people in Wales are twice as likely to try an e-cigarette compared to tobacco, according to research from Cardiff University.
Research published in the British Medical Journal Open suggests that youth experimentation with e-cigarettes has grown rapidly since 2013
The study concluded that there was no evidence that e-cigarettes make young people more likely to smoke but warned that youth e-cigarette use may become a public health problem if left unmonitored.
According to the research, older students and male students were most likely to have used an e-cigarette.
The study consulted over thirty thousand 11 to 16-year-olds from 87 different schools in Wales.
