As I said in the Aroma ejuice subforum, the main difference to me is as follows, and you can agree or not as you choose:
Tobacco absolute is a consumer product. I can go to any of the better DIY shops and order "5mls each of banana flavor, caramel flavor, tobacco absolute and cotton candy flavor, please", and make my own banana, caramel, tobacco and cotton candy juices. Another person can buy the same flavorings and make juices that taste exactly the same.That 5ml bottle will have the concentrated essence of a dozen tobacco plants from who knows where.
NET is not a consumer product. It is made artisanally by the e-liquid maker solely for vaping purposes, and is only available to them (exception: My Vape Juice who sells their NET concentrates to home DIYers).
I am unfortunately one of those who dislikes TA intensely. I don't really care where it comes from as long as it doesn't wind up in my juice
Shatner: that Tom Ford is a wicked good fragrance. Have you ever tried Eau d'Italie fragrances? Their Bois d'Ombrie, I'm fairly certain, has tobacco absolute among its base notes. Smells a lot better than it tastes
