aalwani - I have been contacting DIYflavorshack about trying their VG-based tobacco flavorings, and they have told me that they were soon going to offer them without having to purchase the entire Shake 'n Mix kits.
From what I understand, long ago, Ben had talked to the proprietor of DIYflavorshack, and it was their advice that motivated Ben to start DIY, which of course led to Alien Visions being created et cetera.
Personally, I think Dawn (is her name?) gave more than just motivating pushes, I think she may of also given Ben advice on how to make his own NET's (naturally extracted tobaccos). With what little evidence is available, personal experience, and information gathered from others' experiences, I really believe that they are using some sort of NET in this blend.
The reasons being, 1. This blend is FAR too thin to be labeled as purely 100% VG (leads me to believe that he is using distilled water to thin the blend, or!, water based tobacco extracts) -> This is further feeding into my suspicions as being feasible due to Ben making mention that they use nearly 50% flavoring in their blend (if 25% is the water based tobacco extract, then that would account for why it isn't as thick as pure VG). 2. Ben makes mention that the blend cannot be offered without at least some nicotine (once again, direct point to a NET).
Now, what does this have to do with DIYflavorshack's VG based tobacco flavorings? Probably little, to nothing at all. I was just making mention that there are indeed tobacco flavorings that do not have PG, or alcohol in them.
