Lacking soot and tar, I find it hard to believe vape products are as harmful as smoking in principle. Of course there may be other factors in play; for instance it seems plausible that some vaporizers might out-gas other harmful chemicals when they get up to temperature. The use of plastic parts in such devices seems pretty sketchy. That's my strong intuition anyway. I don't have any skin in this game; I don't consume tobacco products in any form.
