Yes, it is a bit confusing as evidenced by your somewhat confused post.
The addiction is to the psychoactive spread of chemicals in cigarettes, many of them being tobacco alkaloids. WTA is not present in tobacco, WTA refers to an eliquid product containing alkaloids purified from tobacco. It contains the active alkaloids (including nicotine) but all other tobacco chemicals have been removed during processing. So again, tobacco does not contain WTA, it contains tobacco alkaloids. Processing and purifying these tobacco alkaloids into an eliquid produces WTA eliquid or WTA. If I had a nickel for every time somebody confused WTA for the alkaloids present in tobacco...
WTA eliquid is available and is a much better alternative than smoking for ecig users who are having trouble getting over the cigarette hump.
Your vendor FAQ is from a vendor who has been out of business for about a year after taking a number of folks money and not delivering the goods.
A much better FAQ is available from a currently active vendor who focuses on product quality and customer satisfaction.
I never did say to buy from that vendor, nor do I recommend switching to a WTA juice. To me, with someone who has relapsed back into the stinkies needs to get away from regular cigarettes, and the closer something is to a cigarette, the greater chance there is of a relapse back into cigarettes. I recommend trying both analogs and Ecigarettes together.. but slowly ween yourself off the analogs. Nicotine is a psychoactive drug.. as I said in my earlier post, it "trains your brain". The trick to getting off of Cigarettes is not to simply quit or substitute, but to re-train what nicotine's already trained your brain to do. A WTA e-juice is somewhat counterproductive if you stick with a WTA juice. It's not JUST the WTA's the OP is addicted to, it's the other 2000+ chemicals. Even switching to a WTA juice is not the answer, but it does shed some insight as to what is going on with the addiction.
I could write a five page essay on how addiction works, and how E-cigs are not working for her. I could break down the individual components of smoking, but chances are, if I did, it wouldn't be read. I have to simplify things, which is what I did, perhaps too much so that it's confusing. Even your post is somewhat confusing...
WTA is not present in tobacco
WTA stands for Whole Tobacco Alkaloids.. It is other components of tobacco that is not in most E-juice. IT is extracted from tobacco, and IS present in tobacco. It is one of the many components that is present when someone smokes a cigarette. It is also PART of what she is addicted to. There is also many other factors in the addiction. The holding of the cigarette, the smell of the unburned tobacco, the act of packing the cigarette, the act of lighting it, the squishiness of the cigarette, the visual of the smoke as it rises, the taste of the inhaling tobacco, the hit at the back of the throat when you are inhaling it, the smell and taste of the burning tobacco and the woosh sound you make when you exhale, the whole experience is what she is addicted to. The nicotine has altered her mind to equate the whole experience as being gratifying while the tar builds in her lungs. It leaves a reminder of the whole experience by leaving a smell in her hair, in her car, on her fingers, and in a little dish beside her called an ash tray. It's a wholly evil process that is self destructive where no true good comes from it except to line the pockets of the tobacco industry.
Now, you enter Ecigarettes. there is a whole range of products that can help "trick" your brain into substituting that whole experience to something that many times safer than a pure tobacco solution. Now, if she so chose, she could replace: The smell of the ecig as she takes it out, the squishiness of the cartomizer as she holds it, the turning it on substituting the lighting, the inhaling of vapor instead of smoke, the light at the end of a cigalike as she inhales the flavor of something more pleasant than smoke, the woosh of exhale is still there...all while using something that has nicotine. That is why Cigalikes are and will still be around as long as cigarettes are around, they mimic the whole smoking process to help re-train her mind to get off those stinkies.
After she gets off of real cigarettes, she can start weening herself off of the whole process, but substitution is the hardest part. Switch away from cigalikes and going to a larger battery is a key component, since it mimics the availability and on demand process of a traditional cigarette. Then switch to a juice that's further away from cigarette, then the lowering of nicotine itself is recommended.
I have been addicted to cigarettes for over 20 years. At the height of my addiction, I would buy Marlboro 100's and rip the filter off of them and smoke them that way. I have come a long way, and I remember what it was like. I haven't smoked one cigarette in over a year, and I'm quite proud of myself. I vape fruit flavors, and a 6mg nic level as my main juice. I use a VV/VW mod and a mech mod which doesn't resemble a cigarette at all. I've turned off all lights on my VV/VW mod when I vape as yet another method of quitting. I doubt I'll ever smoke a cigarette again, and if I do ever give up vaping, I will keep a bottle of E-juice and a PV at hand so I won't have to grab a lighter and cigarette.
These have been my experiences, and anyone that wishes to quit analog cigarettes, please take what I've said.

I was lucky enough to need a WTA juice, so I did not know about their business practice. WTA juices may be a necessary step to quitting for others like the OP, so Thank you for that redirected link.
Keep calm and vape on.
