I'm still here and very interested. The juice I usually vape, Vermont Vapor's Tobacco, has some degree of the other stuff in it, but I'd like more.
I'm the same as Phayah. I have been vaping now coming up to 3 years this March and it has NOT worked for me. I smoked over 50 RYO a day + i would smoke a pipe and a few cigars were all in my daily rotation, whatever took my fancy. I have been a heavy smoker for over 50 years and i doubt if i would/could ever totally kick the habit. Now i have cut down quite a lot by using my PV but i still smoke real tobacco daily. The PV just got added to my daily rotation and fill the gaps between my real fags or my pipe. When i am out among company of smokers, vaping is a waste of time and the real tobacco is the main dish on the menu. I have never had a buzz from nicotine but i know when i have had enough, i get the Hic-Cups. This is quite rare and normally only comes when clenching my pipe in my mouth, hogging into my Condor.
It is extremely unlikely that Vermont Vapor's liquid has any minor alkaloids. When they talk about tobacco extract they are talking about tobacco flavor, not WTA. I know this it is commonly mistaken for a true WTA extract and you are not the first to get a bit confused by the issue. I'm not saying it's bad liquid, just that it is not WTA. Vermont Vapor have rightfully made no claims that it is.
I'm going to suggest some high octane tobacco in the form of snus. Not the US made camel but the real snus from Sweden. They make some extra strong brands that I couldn't touch, but you would likely do quite well with. Come on down to the smokeless section of the forum and say hello.
