If anything is extracted from tobacco, all you're really getting is flavor and a tiny bit of nicotine. If it says Whole Tobacco Alkaloids, this means that some of the junk from the tobacco is included as well. Very few companies use WTA and they'll advertise it as it's a pretty hot seller right now. If you don't see WTA anywhere then there's nothing to worry about.
Is WTA safe?
This question should more properly be, "Are e-liquids safe?" Certainly WTA avoids the
many by-products from tobacco combustion, but there can be trace carcinogens known as
tobacco specific nitrosamines (TSNAs). These TSNAs can be present in E-juice, NRT's,
snus, chew, WTA, and any other product derived from tobacco. NRTs show the lowest value
of TSNAs. Whenever you have a tobacco product, it will most likely contain some amount
of TSNAs. With products derived or extracted from tobacco there is always a chance of
inhaling these TSNAs. The safest approach is not to ingest any form of tobacco product at
all. By using e-cigarettes we are aiming for a reduced risk versus smoking tobacco, but there
is risk. WTA is a more complex mixture than an e-liquid containing only nicotine. Logically,
WTA is not as safe as a nicotine only e-liquid. It is, however, this increased complexity that
we believe affords WTA the ability to help a struggling vaper not fall back to smoking analogs.

I'm sorry I didn't mean to sound like WTA is evil, I meant that it's not as safe, as shown from an actual WTA vendor. The research is not solid yet on it. It is very helpful for those that don't want to risk their health with super high nic liquid.
I also didn't say 100% safe. Nothing to worry about was carcinogens. I addressed the concern of the OP. Don't put words in my mouth.
