Has anyone tried something like this? Putting the liquid on a piece of gum, or something else you can put in your mouth, instead of vaping it? Of course it wouldn't be the same as vaping, because the nicotine would be absorbed more slowly through your gums instead of lungs, but if you are concerned about inhaling the chemicals (diacetyl and others) in certain flavors, then maybe oral administration is an alternative? Since all the ingredients except nicotine are approved for use in food, it shouldn't be very risky at all. As long as you get the amount of nicotine right. I feel like regular e juice is probably too concentrated for this, if I soaked a cotton ball in my favorite liquid and put it in my mouth I think it would result in a minor overdose and ER visit. Anyone have an idea about the right concentration? Maybe just start at 1mg/ml and go from there?
