    Once again, another piece of bull probably coming from big tobacco or big pharma. YEAH because smoking cigarettes are like sooooo healthy compared to using this. You know what. What this article doesnt say is how much of the so called harmful chemical is there compared to burning tobacco or any kind of vegetation. The formaldehyde report didn't work. then later the immune system problem report didnt work too. Now you guys are just scrambling to come out with something right?
