Greg isn't as well informed as I would have hoped he would be. I believe 95% of the members on this forum could have done a better job discrediting that doctor than he did, but I reckon it's better than nothing at all. At least the doctor wasn't well informed either. Funny doctors keep throwing up the formaldehyde argument that's been debunked. Greg did put her on the spot though when he asked her to name which studies she kept referring to and she couldn't. She just kept saying there was a lot of studies but she kept saying in the same breath that there hasn't been enough studies done on the effects of vaping. Made no sense what so ever. Horrible segment IMHO.
