Quitting smoking is always one of the top New Year's resolutions.

But while e-cigarettes are marketed as a non-tobacco alternative to traditional smokes, they remain controversial and arent tightly regulated everywhere.

Health Canada says it has not authorized any electronic cigarettes with nicotine or health claims.

Health scientist Bruce Lanphearof B.C.'s Simon Fraser University wants to find out how much safer e-cigarettes are compared to their tobacco counterparts.

"Maybe it's analogous to, 'Is it safer to have a pistol as opposed to an AK-47?' Lanphear said.

One million Canadians will die as a result ofsmoking in the next 25 years, according to Sweanor.

"They are all already smoking," he said.
