I agree with Jeff M.
"You might try Tobacco Blend from ECBlendFlavors. I wouldn't say "Marlboro," but it is dry, airy, smokey, and has a cigarette taste for sure. Somewhat ashy.
(I don't know why anyone would want to taste cigarette with all the wonderful flavors out there)."
One word of advice. I am still in the process of qutting the analogs. Down to about 2 or 3 a day. I like you, sought out all the possible tobavvo flavored juices. THought those who kept lauding the value of flavored juices were, well--off their rocker. I guess a couple of the non tobacco ones I got were so dang sweet, it was like licking the sugar bowl. Never been a big fan of sweets. So I bought and I bought and I bought anything that had the word tobacco in it. Now I am drowning in tobacco flavored e-juice and now I can't even stand the look of it. The advice---go ahead and buy some (not all) of the tobacco flavors out there. CHoose about 2 that you hear about in this quarry and also get just a coupld of non-tobacco juices. Yeah, I know, right now that is counter-intuitive But, I think, in time, you will be surprised about what you reallyprefer. Good luck and enjoy the hunt.
