Recent study done in England seems to think it's a hell of a lot better than traditional cigarettes.

If I fall off the wagon, I'd be looking at an ecig for sure. Apparently e-cigs will now be regulated by Health Canada.
My only concern with e-cigs atm is apparently the heating coils can give off some pretty bad fumes. That may be due to crappy/cheap ones. If you buy one made in North America with some quality to it, I'd imagine that's a better choice.
