oh yes and of course, we dont exactly carry a tube to inhale the regular dust (which doesnt include carbon) that we kik up with our shoes against the carpet, besides, as far as standard dust, we already breathe enough of that, but when one is buying a device for the purpose of taking less crap into there lungs, who wouldnt be concerned that they are inhaling carbon dust, at least that is the standard but, it may also contain lead, and being made in china it most likely will have lead in with the carbon, and for those of us who are alert and watchfull, we wont be prey to such things, on the other hand, those of us who want nice clean vaporization, cant get it with carbon and lead.. what? no lead? how do u know? do u want to take that chance? remember china is not a good government.. already years ago they put a chemical in PLAYDO! that screwed up childrens reprodutive ablility and they couldnt have children. I dont think i want a country like that making a health product for me and i dont want to spend the money nessesary for research on a want to be vaporizer, just buy the real deal and be happy! VAPE ON!
