Ahhhh a topic I luv to bust...
VG PG "attracts" about 40% of its volume ( max) in water... so if you vape 100ml of juice in a day, you loose 40 ml of water from your system due to that function...
and Bad, Im gonna pick on your post... " Humectants are ingredients found in lotions and cleansers that hydrate the skin by
attracting water molecules like a magnet."
"The Pg and Vg in the vapor allegedly will attract water (moisture) from the mucus membranes, resulting in a dry mouth and throat."
HUH??
If VG/PG coats the mouth when vaping ( as it would like a skin lotion to attract moisture) then it should moisten the inside of the mouth shouldnt it?? and Im glad you said allegedly too
