for vg affecting chest/lungs it seems it depends on source or producer of vg.
i diy my juice, when i was using life brand vg it did make my chest feel "heavy", for the lack of a better word, when mixing high vg juices.
i then ordered a gallon(4liters) from coop coco and i didnt get that heavy feeling. maybe its just in my head idk.
info on coop coco's Vegetable glycerine: certified GMO free, pharmaceutical grade (USP) and kosher,
Origin: Coconut
Glycerin, vegetable source USP | Coop Coco
imo, ymmv
