There can be health benefits to vapors, we use diffusers in our house with either frankincense oil or cedar oil, it disinfects the air, opens airways in lungs and moisturizes the air. You could say we are not vaping though but in a way, yes we are. And the doctor told my or suggested to my wife that she do this in our bedroom for her Psoriasis/ arthritis. Here is the deal, it's healthy if you don't over do the cedar, cedar has a health benefit element till it gets to strong. But we are inhaling vapor here in the winter months, day and night and the rheumatologist suggests we keep doing that. My wife will have less outbreaks. By the way frankinsense while expensive for the good stuff helps produce a peaceful and very sound sleep. Cedar is better out in the main house.
But you say this is not nicotine. True, but it is vapor !!
So you can't just say in a blanket statement "vaping kills", that is misleading.... Vaping with the wrong materials kills, yes, that is proven....
