Re: Battery problems aside..
High powered devices don't really superheat the liquid - that's not to say it doesn't get a bit hotter than lower powered devices. What does happen is that you'll be inhaling more "e-liquid" (dumb phrase but we're probably stuck with it), which definitely increases risk.
But to the level that smoking causes? Not a chance. You could probably drink the e-liquid (assuming it's zero nic) by the gallon and still be at a far lower risk than smoking.
