Has anyone tried Whole Tobacco Alkaloid E-Cig Juice?

After all the research I have done it appears that smoking tobacco appears to be one of the most effective methods at reducing symptoms of UC. Some try to say that this is only true for previous smokers but my research has shown otherwise. Like many I have never smoked tobacco and never want to, but I do want to figure out what in smoking is helping so much. I like many others would probably consider an effective smoke free treatment provided conventional treatment was not working well enough. Many have tried generic e-cigs juice and chewing tobacco but did not achieve results as significant as when they were smoking. I believe that it is possible that the issue with this is that the common e-cig juice does not have all of the tobacco alkaloids and chewing tobacco does not use the same type of tobacco that is used for smoking. The chewing tobacco is higher in nicotine but lower in the other alkaloids. I'm curious as to if there is a large enough population that have tried whole tobacco alkaloid juice and to see what there results were. If not promising than it would appear that either the hydrogen cyanide, carbon monoxide, or a combination of any of the 4000 chemicals produced from combustion seems to be doing the trick.
