Research is great but common sense is a good starting point.

We know lungs are very sensitive and easily accumulate shit in them. Therefore the reasonable position is to assume that anything you point into your lungs is harmful, unless you have extremely strong evidence that it's not (as opposed to assume that something is safe until evidence that it's not.)

So: assume that e-cigs will give you lung cancer.

But of relative safety viz-a-viz regular cigarettes: is it not possible to assume that e-cigs are safer than regular cigs?
