A New Zealand doctor believes shifting smokers onto e-cigarettes is a "win", saying that they "are going to be absolutely fantastic".
E-cigarettes are becoming increasingly popular among smokers, with new research suggesting that while they may be better than smoking traditional cigarettes, they come with their own set of problems.
On TVNZ's Breakfast programme, Doctor John Cameron said "if we can get everyone who's smoking tobacco related products and put them onto e-cigarettes, I think we have got a win".
"We know that the best thing to put in your lungs is fresh air, no question about it, the worst thing that you can put into your lungs is burnt tobacco leaf," he said.
"Vaping sits somewhere in the middle there where there is nothing wrong with nicotine as a drug, it's the delivery system if your burning organic matter, that is where it goes rubbish."
Talking about the down sides of e-cigarettes , Dr Cameron said there is a risk people may turn to vaping who have never picked up a cigarette and smoked it before.
"You are developing a behaviour which is inhaling a substance that may or may not do some damage to your lungs, it's probably minuscule but are we going to say it is a good thing to do? So that is where the conundrum currently lies."
