I am new to vaping and I have a lot of questions about what is in the smoke juices- I am not talking PG or VG and the elusive "flavors"- everyone knows about that. But what about things like artificial sweeteners (which degrade into toxic products when heated) certain toxic artificial dyes or anything that might be allergenic (even food products) etc. I am as concerned about what is in the entities that I inhale as I am to what is in the food I eat or air I breathe or the water I drink or the products that I apply topically. But I notice that on this forum everyone just bristles if you mention anything about labeling and about ingredients. A lot of people have sensitivities to certain food, scents, food coloring etc. So to me it is a legitimate and informed question. We ask for disclosure on all products that we are in contact with and exposed to. So Why are people on this forum so defensive and even hostile when someone asks about what is in smoke juice? My Dad smoked Kent cigarettes for their micro filters and it was later revealed that there was asbestos in the filters. So why is it wrong to want to know if there is anything harmful in the smoke juices? Not to mention the fiber fill in cartomizers? Isn't it wiser to know what you are inhaling than burying your head in the sand? So.. What am I missing?
