I was wondering if anyone out there knew of a recipe or if this was even possible, I did quite a bit of research with mixed results and I trust the community here much more than on any other sites. My plan is to buy USP grade VG and make a slow cooker tincture to fill up a 808 cartomizer. This seems like the most discreet way to vape literally anywhere in public openly if it works as theorized. Thanks in advance for any help
