I got as far as the second video in this link and got pissed off and stopped. This "doctor" sounds just like so many of the uneducated nit wits I've run into at work. These idiots believe whatever they hear or read on the internet from biased sources with no research at all. What's sad is that so many really look up to this man and will take whatever he says as gospel. He's as uninformed as many Joe Blows off the street.
And as far as the lady doctor...."E-cigarettes have only been around for probably a decade and that's not enough time....etc....." Bitch, if you can't make an educated assessment of something in TEN YEARS, there's obviously a lack of dedication and purpose somewhere. If the FDA/AMA wanted a thorough clinical investigation on this matter, they could have it in much less time. But I guess it does take time to figure out how any study is going to placate us in correlation with the desires of Big Pharma and Big Tobacco....AND the tax man.
Preach it, Dr. Oz. It's falling on deaf ears at my house.
