My understanding is that the metal doesn't get hot enough to bind to end up in the vapor in any quantity as long as the heating element is immersed in liquid. A "dry hit" is when you take a drag on the device when there is no liquid or not enough liquid in contact with the heating element. It tastes terrible, burns out coils faster, and burns your throat.

The only study I've seen that shows that heavy metals in vapor is an issue used conditions that are unlikely to occur in "real life" because of this. The argument seems to be that one could become accustomed to it through the cravings associated with nicotine withdrawal, but I honestly find that unlikely. In reality, you'd burn your coil up in short order, and if you can afford a new coil you'd have been buying more liquid in the first place.
