Nhaler make a series of juices called Lung
juice. They are VG based and have a bunch of herbs in them that are quite healthy, but I'm not sure if they still are once they are vaporized.
I can't post the link because I have not made 15 posts, but if you google Nhaler, you will find them at the top.
Reasonable prices and great service. I buy from them and Totally Wicked for all of my
juice now. Totally Wickeds juice seems to leave less residue, but I assume that that might just be the effect of using less VG because VG is thicker.
