Good Point.
I just did a quick Google/Youtube seach on that doctor "Dr. Marc Siegel" It seams that every subject he talks about he hate and try to tell you not to do it. I think he's getting paid to talk negatively about any subjects.
I just looked him up too. The guy is laughable, to say the least. You guys should go to doctorseigel.com, and look at his "about me" page. Here's the highlights...
"Dr. Siegel is the author of False Alarm; the Truth About the Epidemic of Fear, and Bird Flu: Everything You Need to Know About the Next Pandemic"
See? Even his own books contradict each other.
"Dr. Siegel is also a columnist for the LA Times; his bi-weekly column The Unreal World examines TV and movies for medical accuracy."
Ooooh, some life-saving work there, Doc!
So, yeah. Another establishment media leg-humping pseudo-celebrity/doctor, paid to speak on behalf of big pharma. Glaxosmithkline probably bought his dumb ... a Lexus for stating his desire to see "prescription only" e-cigs.
But, he must be an expert. He's on TV, right?
