It’s likely that the (closer to the mouth) coils used were titanium. It can be done but is not recommended. Titanium can cause a class delta fire when heated too much or too quickly.

Possible, but still not going to cause an explosion with enough force to break the mandible AND they are still a couple of inches away from the lips in most e-cigs and usually enclosed in a brass tube.

Hmmmm. My surgeon didn't tell me that before putting them in my hips.

Of course if I'm in a fire that hot, well, I doubt I'd know the difference......
