Hi charlzrocks, vjc had some great recommendations with NET.com and Goodejuice.
NET.com sells a Nat Sherman, which is a cigarette-like juice. Goodejuice sells Analog, another in the same vein. The Plume Room also sells M-Type -- you guessed it -- a Marlboro type vape.
I'll second and third what's already been offered in response.
Analog and Wrangler Lite from GoodEJuice are straight cigarette-type NETs, as are Big Spirit (American Spirit) and NS Dark (Nat Sherman) from NET.com. Having extracted both Nat Sherman MCD and American Spirit Organic cigarettes in my own home-brewed macerations, I can attest that both specialty cigarettes make terrific, straight-ahead natural tobacco extract and juices, with no cigar or pipe notes at all, and yet they're well-blended with sufficient complexity to be interesting and satisfying, not at all one-dimensional (as is the case with some of the single-leaf extractions).
A big thank you for the info....I will investigate these supplier offerings in the near future as finances permit. Meanwhile, I will always be lurking nearby!! LOL!!
