I just got my new juice from T.V. It tastes really good and I love it. The only problem is that it does not produce as much vapor as my old juice from nhaler. When I ordered it I got the 100% PG mixture, but there were a couple of choices to have 10 or 20 VG added to the mix. So, my question is can I add some VG to increase the amount of vapor that I am getting?
