I've cut back from 24mg to 6, but was edgy and fuzzy with that, so went back to 12mg for now.
I don't really care about TH either, I prefer mild/sweet tobacco, but some say there is not a TH on pure VG. Maybe a little with PG, I can't tolerate that either.
I've seen a couple of people that use something called black pepper oil extract for TH. Not something I'd try though. Bit of menthol, maybe? (Make it tiny bit, it's strong!)
