I would never trust any e-cig or e-juice put out there by BT. They have millions for PR; but their very identity quite rightly toxifies the marketability of whatever they might think up. It's not gonna happen. Consider the following:
---
E-juice is as simple & generic a thing as it can be. There's no way for BT (or anyone, for that matter) to patent it, or ever corner the market.
The only relevant questions for customers would be 1) Do you trust BT? and 2) Do you want to support BT financially? My answer to both questions is hell no. You'll find that many feel the same way, with good reason.

E-cig technology is also as generic as it gets. Granted, there are some early patents out there, mostly dealing with now-obsolete models...but even they are very narrow & specific. No can patent the concept of a car, for example. One can patent a unique design, for a limited period of time...but yeah. The basic technology of a battery, atomizer, cartomizer etc is now well past any risk of patent issues.
Again...this means that BT (and anyone else, for that matter) would have no way to ever corner the market. E-cig brands that do well, do so because customers find them to be superior.
In BT's view, there's just not enough profit in vaping for them...and vaping spells the doom of their long-standing mainstay (cigs)...and they know that they are (rightly) universally reviled as untrustworthy & evil. BT knows all of this...they have no illusions about their ability to survive, now that vaping has arrived.
And so, they've clearly chosen to forestall the inevitable as best they can, by doing everything they can to prevent knowledge of vaping & e-cig/e-juice availability from reaching the mainstream. Only the public's lack of knowledge, & the lack of market visibility for e-cigs, keeps BT on life support right now. Many smokers have still never even heard of e-cigs. Many who have, have only heard misinformation & lies. BT (in cooperation with big pharma, the government & even some allegedly anti-smoking groups...all of whom depend, or believe they depend, on the status quo) is simply milking what they can, for as long as they can, before they inevitably go the way of the dinosaur.

No one in their right mind trusts BT, or likes them or wants to be their customer. They have enslaved generations...selling sickness, misery & death in bright little packages.
They still are.
So I wouldn't be rushing to give them one thin dime for anything. I wouldn't trust them to not add goodness knows what chemicals etc into the mix. At best (and I honestly don't even see this much happening, necessarily), I could see BT becoming little more than the 'Bing' of the e-cig world; a self-important, largely pointless offering...with overpriced product of dubious quality & safety...and with a tiny, tiny share of the vaping market.
