Alright, still catching up, but I did see a comment about VG being used in nicotine vaporizers, and thought I would add that a lot of those mixes are flavored with lorann candy flavors.
http://www.lorannoils.com I have not made a tincture, but have made my own Eliquids, and this stuff is great. Lots of flavors, and all food grade. At least most, they have a spa section I have never read.
Back to reading!
Edit: All caught up, and will be trying this. I have made an alcohol based tincture, and it works great, but I can't stand the taste. The VG does look more promising. Thanks for sharing and testing!
