I would also like to report some results from some personal experimentation. At the suggestion of some of you, I purchased a KR808D-1 with various strength cartridges (Cowboy flavor). I used it last night (18 mg cartomizer) and tested my urine with Nicalert strips this morning. Result? 5/6. Clearly, this result is consistent with recent nicotine exposure. The confusing thing is this: I used the device while hooked up to a heart rate monitor which an observer was watching and I was not. My heart rate showed negligible changes during my many puffs on the device (it was one with a manual switch, which I was pressing; I was using the USB pass through; yes I got vapor, and yes I inhaled – quite the throat hit, I can assure you). Obviously I am not going to write a paper about this single experience, and there is much to be learned, but I certainly agree with the many of you who suggested that these devices may very well behave differently than the ones that I tested.
