Here. what I'd suggest. Get a pack of Camel Snus Frost, put a few drops of your JC juice on it and squeeze it out and then try vaporizing that.
I'm having trouble quitting, but recently read a thread on disolving snus in PG. I disolved mine, Camel Mellow, in water and used glycerine. I tried the end product today and didn't look for a cigarette until now while I'm cleaning the atomizers.
(Since the solution was dark, I thought it might leave more residue, so I did an alcohol soak, coke soak, hot water soak... now to blow dry to prevent rust.)
Try the Camel Frost, it has a nice flavor and you probably could salvage the whole bottle with just one pouch of the frost. Try a small sample 1st and see if you like it.
Best of luck with whatever you decide!
(BTW. TropicalBob posted in a thread that some of the bad stuff is in some of the snuses. I don't know if that matters with such a small quantity. But, I thought I should mention it.)
