My little vial of Flavourart Latakia came in a few days ago, so yesterday I thought I'd experiment--very conservatively, and I needed to mix up some more TV Tobacco and doubler anyway. So I made up 8ML and added just two drops of Latakia. Ideally, I guess I'd be waiting some days to let the mix marinate (or whatever), and other factors like the condition of my atty and what's been in it may be playing a part. But a day later, I think I'm getting that note and liking it. It seems to add just a touch of harshness that I like. A couple or three more days may tell more. (It'll last that long at least, since I vape other stuff in the course of a day.) I suspect I could have gone heavier with it, but I'm looking at this as a way to fine-tune a flavor that I already like, rather than create something dramatically different.
