As far as flavor goes, the Hangsens are true tobacco flavor like the tobacco absolute. I would bet they're exctracted from real tobacco.
The couple of Hangsen I have are way better than TA. I would have never messed with tobacco absolute had I found these first. Hangsen's gives way more flavor at lower percentages. TA, by the time you mix enough in there to get a flavor, leaves so much residue on the coil.
