Re: Quantum Vapor Tobacco+
"First off, thank you for the comments. They are much appreciated.
As for the extracts. We do not extract our own tobacco. In a sense there is no such thing a natural tobacco flavoring aside from extracting the essence of tobacco leaves. This has a side effect in that you may extract the nitrosamines, known carcinogens, from the plant itself. Also, unless properly heated and filtered, nicotine can come into the mix and throw off the overall liquid. Its a long difficult process.
Given that, our tobacco flavoring is a combination of other natural flavors to 'simulate' a tobacco like flavoring. This is why it has a nutty essence to it. In fact it's why almost all ecig tobacco flavors have that nutty flavor. Some more or less than others.
What we achieve is a clean taste which is all anyone can hope for. We would much rather use proven, natural/organic extracts that provide a clean taste than provide our customers with any level of the uncertainty that comes with self-extraction.
We are happy that you enjoy the tobacco+. Feel free to let us know if this helps and if you have any further questions or concerns. You may also call if you like
Kind Regards,

So not a NET, but definitely other extracts. I'm curious what is used, but I'm sure that's privileged information.
