There's a call for stricter regulations of disposable vapes.
It's over concerns young people are attracted to products that are flavoured and will progress to using tobacco products.
Consultant at Crumlin Hospital, Dr Des Cox, says research shows those using e-cigarettes at a young age, will try other possibly more harmful products when they are older:
"They're also often very colourful. They come in different flavours. So, the research has shown that these products are very attractive to young people and teenagers. And then, there is now evidence from the Health Research Board Review that showed that adolescents who use e-cigarettes are four times more likely to go on to use tobacco products".
