The impact of this confounding is that it will bias the results towards finding that e-cigarettes are much less effective than other approaches.

So I took a chance and used it on my personal vaporizer. I checked my resting heartbeat at the beginning of the hour and checked it again after an hour of vaping the caffeine infused E-Juice. No difference. So great I’m not going need hospitalization which, of course, is fantastic news. As far as how I felt, I really felt no difference at all. I didn’t get the sudden jolt of energy when I normally have an energy drink or a cup of coffee. So I decided to continue using it for the rest of the day just to see if it took longer for the caffeine to kick in for some reason.

The FDA is essentially saying that ex-smokers who have quit smoking using electronic cigarettes might as well revert back to smoking, since the Agency is not aware that vaping is any less hazardous than smoking. Is this the kind of scientific-based advice that we think is appropriate to be coming from a federal health agency?

To make matters worse, Dr. Samet is not just an author, but served as one of the two editors of the report.
