With nicotine gum and lozenges it's quite common to swallow some nicotine inadvertently and that can upset people's stomachs (not mine, but I have a stomach of steel). This can happen while vaping too, often if there's spitback or flooding, but most people who have choked on something or accidentally tried to inhale something they were chewing (I have done both) know that the respiratory system and the gastrointestinal system aren't quite as "divided" as one might think. You can also get nic juice on you when you are filling, and wind up accidentally tasting that.
Some vapers do have trouble when transitioning with "swallowing" e-liquid various ways.
I don't really have much more to say about this study other than I think it was flawed, unethical, oh I could go on with the comments, but I'm done with it.
This particular study doesn't leave me all worried about the effects of nicotine on my cardiovascular system, I let MY docs worry about that, not Glantz. He's not even a doctor. And yes, the Juul is potent, and out of all devices I could see it leading to a nicotine dependency.
With that said, all brains are different, and some will find it easier to stop vaping than others regardless of whether it's' the Juul or another device.
I completely understand (and to an extent, agree with) the concept that a nicotine dependence is as easily dealt with as a coffee addiction. I would probably have a hard time giving up coffee, although I've done it before. My brain just likes to addict itself to anything nearby to hand, so I'm just glad it's not cigarettes any more and if at some point I have to give up vaping because my doctors tell me to, I will deal with it then. Etc.
I don't think the Juul is "more addictive" than other vapes, it's just the vape of the moment. Just like with anything those who choose to use it will have a difficult time... Or not, depending on their brain chemistry, addiction level, or whatever else. Etc. I don't think it requires school conferences or other valuable time, but I am of the short who considers "addiction/dependence" a part of life for some people in some form for everything. Better the Juul than tobacco is what I walk away with. If I were offered a Juul or a pack of smokers, I would choose the Juul. But, that's me, where I'm at now and probably EVEN in today's environment as a teen, I'd probably desire to smoke cigarettes more, because I was "that type" of teen. I didn't sorta decide to start smoking at 18, I had "smoked" before, it was just that someone taught me to inhale.
