Also from their site:
It is still an open scientific question whether e- cigarettes might be able to help adult smokers give up cigarettes;
Those people are clearly a bunch of not too bright extremists, because I have conducted my own scientific experiments (as countless others around the world have also done), with me being the test subject, and I have clear scientific evidence that vaping does indeed work, because I haven't smoked a single cigarette (not a single one) since I first began vaping, which is many years ago.
My science and my own real world experience trumps their bogus claims and their "science", or whatever nonsense it is that they choose to believe in.
I don't need any scientific study to tell me that vaping is the best thing to ever come along for smokers looking to kick the habit.
The last thing that I need to do is to listen to the false claims and propaganda coming from a bunch of people with an agenda, an evil and corrupt agenda.
