NET is the big net that most vapers get caught in, buying the negative propaganda that non WTA vendors spew out to look to keep their customers from leaving the
vaping purgatory that they are caught up in and ascend to the much more heavenly experience that only WTA provides.
The thinking here, or lack thereof, is eerily similar to what anti
vaping people try to use. They do their best to create an air of uncertainty, and then use whatever doubt they can create about the safety of what we're vaping to look to scare us. So the line that they really haven't tested juice moves to they really haven't tested WTA, although regular juice suffers from this specious argument as well.
They also forget that the assumptions of safety that we make toward regular nicotine juice is in reference to its comparisons with the harms of smoking tobacco, where we are moving to what is a clearly harmful product to one that must be worlds apart in terms of safety. They forget that this is the same rationale that we use to assess the risk profile of WTA, where once again it's a hell of a lot better than smoking.
People say that nicotine is only an alkaloid like caffeine, so we don't have to worry about it, but forget that the additional components of WTA are alkaloids as well, and therefore would not be something we really need to worry about as well.
The main thing that gets them trapped in this net is the fact that their minimalist approach, where they are on a mission to get by with the least amount of substances, neglects the very important fact that for a lot of people, regular juice fails in its mission to satisfactorly substitute for smoking, and people have to look for alternative substances such as snus or even going back to smoking, or even more often, continuing to smoke.
If they truly are minimalist, they would only vape unflavored juice, and if there is anything that might be something you don't want in your juice it is some of the additives that are in flavors. High quality juice avoids this, but their thinking would indicate that none of us should ever vape flavored juice of any kind, why take a chance?
I had resigned myself to smoking the rest of my life quite some time ago, and made the decision that perhaps I wouldn't live as long as I could if I quit, but I didn't want to go through life wishing I could smoke. In fact, it really wasn't a choice at all, as after a short time away from smoking, I reached a point where nothing else mattered and I would need to light up again.
So I would define WTA as the only true means to replace smoking while still being able to achieve the same quality that I got when I smoked, which also includes not ever craving smoking even in the least, and standing beside smokers while they are smoking and feeling sorry for them and their inferior experience. What they don't know won't hurt them though, just like what all the dead head nic juice vapers don't know won't hurt them, but while you may resist our attempts to enlighten you, please do not tread on us.
NET can also mean naturally extracted tobacco juice I hear. All this really does is make the taste of the juice more closely resemble tobacco, which tastes like .... anyway and I've no idea why people like it. However it lacks the essential components that WTA has, so it's just another form of crappy nic juice.
