A pro-tabaco indeed would pay for something like this... just call Philip Morris and ask them how happy are they with the grow of vaping... It’s a bad study and for sure was sponsored by lobbists.

This study was sponsored by Philip Morris, you’re welcome! How can those metals be found when the liquid has only 3 elements (glicerine, water and flavor with opcional nicotine with the vape itself beeing made normally with stainless steel) maybe it’s the creationism coming back from the dark ages. BAD $cience...
