Kit- I just ordered (but haven't received yet- seems to e takign al ong time to get hte order) 32 ounces of PG for $17 and I can get soem Swisher Sweet Ciggarettes for abotu $5.00 which will make quite a lot of homemade E-Liquid. I'm not sure how much E-Liquid sells for, but making your own is a lot lot cheaper- and you can buy Bickfords extracts for $3-4 if you want ot add flavors which won't add a lot to the overall cost per volume of E-Smoking liquid even if you bought several bottles. Making hte nicotine juice is quite easy- just boil it down- stir once in awhile, squish the tobacco somehow (You don't even have to do that, but I liek to to get perhaps more flavor out) and then add abotu 80% PG or Glycerin then just flavor to taste.
Bob, I've run straight extract (McCormicks Raspberry extract) in my dry Carts (put neough in until the cart looked good and soaked, but not to point of drpping ouit the mouthpiece) and still the flavor in the smoke was very whimpy- I honestly couldn't tell if it was giving off any flavor- but then again, my sense of taste isn't very good. I'll try a dab of Vanilla tonight, see what happens- but out of Rum, Brandy, Raspberry, lemon, and butter flavored extracts- the only one I could taste really was the butter extract one & it left a long lingering taste that overpowered everyhtign after it.
If you find some good strong flavor combos, good enough to come through the tobacco flavoring, let us know what they are- So far, my experience with flavors hasn't produced anythign too good- even when runnign straight extract into hte carts.
