I'm sorry, and you may legitimately consider this an appeal to authority, but I don't care what you think about this topic, because you are a random stranger, and the people who wrote those links work for some of the best scientific institutions on the planet. If they say e-cigs are unhealthy, I trust them implicitly, even if they sound vague and defensive (Which I'll admit, they do). When these organizations say something, collectively with one voice such as they have, I take their word, because historically, they've been in chorus exclusively in my interest. Over time, if they degrade that trust I will begin to question them, but they haven't yet, and more importantly, you haven't built anything even on the same plane as them, trust and respect wise. The fact that you think you can contend with them, arguing about their conclusions is, to me, the absolute height of Internet Arrogance. Who are you? Why do you have the facts and the people involved with creating the above linked documents don't? Why do you think your understanding of the situation is superior to theirs? Don't you think they've considered, analyzed, synthesized, and thrown out everything you've just said? Hell, where do you think you learned this information in the first place, if not from research done by these very people? You're punching way too far up, and the fact that you don't realize that or don't care shows you're not worth listening to on this topic, or any topic you do the same thing about. Someone once told me that if you don't have an advanced degree on a topic, to not try and contribute to that field without the backing of someone (hopefully multiple someones) who do have advanced degrees in that field. I suggest you listen to that person.
