There is no nicotine in vape juice unless you specifically get juice with nic in it. Putting nic into juice labeled 0g nicotine would be illegal. There are no addictive properties in 0g vape. If you're being tricked into nicced juice, you're probably buying from really bad people. You're getting this information from Big Tobacco and Big Pharm. Did you know tomatoes have nicotine in it? And that peaches also have deathly levels of cyanide? Of course all levels of nic in tomatoes are utterly negligible, and it's only the seed of the peach that has cyanide. But you see that people use part truth to misconstrue information? Spin it to their own advantage?
I said this in a post literally right before you, the only ingredients in ejuice are Propyline Glycol, Vegetable Glycerin, flavor, and nicotine IF YOU ORDER IT AS SUCH. Case studies currently show no detrimental health effects in the short haul, but prospects look very positive to long term effects.
Not saying I'm 100% right, but you're also making wild assumptions based on the information I did find. You're being real jumpy to defend this thing that I didn't even really condemn. The information I found came from a quick search and perusing of some online stores, where you could choose a nicotine content in percent for any liquid. And the nicotine remark was relatively minor compared to my admission that it was my own lack of knowledge on the ingredients that played a major role in me avoiding them myself. I wouldn't say that's influenced by 'big tobacco' and 'big pharm' at all, especially because I already avoid cigarettes and other tobacco products like the plague for a lot of reasons.
To reiterate because you've gone tunnel vision on me, I'm not condemning it. I'm not even saying I'd never use one. I don't know enough about their workings and additives and their chemical reactions when vaporized to come to a conclusion. But what I said still stands mostly true; Most e-liquid at least has the option for nicotine, and we can assume that a lot of people who quit smoking by using e-cigs would take that option. The dosage is generally much less less than there is in modern cigarettes (and look up how nicotine content has gone up since the '70s, it's fascinating), and there's no tar or other things like that in them, but it is still simply an evolution of another smoking alternative. I'm going to let this drop now, because I really didn't mean this much real personal insult with my observations. If you can't take a bit of snarky chiding, then you are obviously debating with the wrong man.
