The way I see it as far as the FDA goes is not get them involved at all. Cigarettes are not FDA approved and never will be. The Manufacture is right in taking steps to make a cartomizer that does not burn the filler material and is clean as possible. Not being approved is one thing but being labeled as dangerous to your health would cause serious problems for e-cigs.

Again, care to elaborate on that?
Your premiss is that the FDA would surely label them as dangerous to your health because of the filler. What are you basing that assumption on?
