do you mean like naturally extracted tobaccos?
if so (or if not) my favorite vendors are Prime
vaping, Vaperite, and Backwoods Brew. they all use extracted tobaccos. so does Vermillion River and Want 2 Vape. i vape tobacco juices almost exclusively and there are very few vendors i think make a good tobacco juice. the above along with Nitelite Vapor and Alien Visions are the go to vendors for most all my tobacco juice. its really hard to beat the authenticity and flavor you get with extracted tobaccos. the chemically made juices rarely are as good if you ask me.
if you dont care if its a naturally extracted tobacco juice i would go with NLV. they are cheap so if you dont like it your arent out much and they make really great juice with some of the best customer service to boot. i havent recieved a juice from them yet i didnt like.
