That will definitely make it more difficult. I know there are a few vendors who offer a 555 blend, which I think is supposed to be like Marlboro Reds. I think I've also seen a menthol version of this as well.
I copied a great post I found on non sweet tobacco juices. Maybe you should look into this vendor?
I can think of many true tobacco vapes that aren't sweet, other than the natural sweetness from the VG/PG.
Have you tried NET's at all?
If you're looking for a tobacco vape that seriously tastes like tobacco, then NET's are probably what you're looking for.
The only other question would be, are you looking for a Cigarette style... Cigarette-style e-Liquids
Cigar... Cigar e-Liquids
Pipe... Pipe Tobacco e-Liquids
Hybrid/Flavored Tobacco... Flavored N-E-T/"Hybrids" (most of these will be on the sweeter side, but not cotton-candy sweet)
Single leaf tobacco... Single Varietal and "Special" Tobacco Types
I apologize that all the links are from one vendor, but they just happen to be my favorite tobacco extractor/vendor.
Have you posted this query in the Natural Tobaccos - Part Deux thread? That's where you'll find the "Experts" in tobacco juices.
Oh, and they do ship internationally, with free samples thrown in!
No I haven't posted there yet.. I will as I know both my husband's favorite pipe tobacco as well as what cigarettes that he smokes.
I went ahead and purchased two testers from your site, just to give them a try.. thAnks for the links!
