Research on effects of vaping on NZ youth causing concern
We need to know before it's too late, that's the message from researchers working to find out the long-term health effects of vaping on New Zealand's young people, who are nearly three times more likely to vape than teenagers in Canada, the US and Australia. It could be decades before we know definitively what impact it's having on their bodies, but as Louise Ternouth reports, some preliminary research is already causing concern.
