He probably extracts em himself. Maybe throw a bunch of winston tobacco in a tea strainer and steep it in x% mg nic pg/vg for a week or 2? Might have to try an experiment when I have supplies to spare.
Doesn't doing extractions from tobacco defeat the entire purpose of using an e-cigarette? If you perform a tobacco extraction in an @home manner, id find it utterly impossible to believe you would be able to remove much of the poisons, unless you have a liquid chromotography setup and half a decade of chemistry experience.
So ultimately you would just end up vaping tobacco extract (and within it, much of the 2000 chemicals you DONT want), which defeats the entire purpose of vaping.....
If your going to rebuttle this by saying "no theyre only extracting the nicotine and tobacco flavors", I say bologne, do you know how hard it is to extract a specific collection of molecules from a composition containing over 2,000 different molecules with different physical properties? If you don't have cutting edge chromotography equipment and a huge resevoir of knowledge of chemistry and a merck index the size of your mattress, I just don't see how its possible.
Maybe if tobacco had 3 chemicals, and you wanted to extract 1, then maybe you could do it, but tobacco is an extremely complex chemical composition. Id be extremely weary of any @home tobacco extract, as its likely just as bad as the real thing which defeats (most) of the entire purpose for using an e-cigarette.
I've always used my boge cartomizes for one flavor only and thrown them out when they quit working. Couldn't imagine the amount of cleaning you'd have to do to test all those flavors
