Wow. I just got done reading this thread. I'm not gonna get involved but a simple question got turned into an argument about if PG is bad to take in. Kinda crazy how the internet works. Again, on nobody's side. But Jolt just put in his two cents then BAM! 3 or 4 people tell him to back up the facts. Which they do have a point. If you say something that's the "truth" then you need some way to back it up. But in my opinion. Asking Jolt's friend to do a whole fucking paper seemed a bit immature to me. I would've said something like go and Google something that backs up the fact of PG being bad. But like any chemical, it's most likely bad for you to inhale. You never know what can go into e juice. But like the first amendment, we all have freedom of speech. So with that being said, Jolt and everybody in that little feud had a right to say what they wanted. Nobody's wrong or right IMO.
