    My exact thought while reading through this. A question I have, did they test other NRT product users (those on the patch or on the gum). If no, this seems to be bias against e-cigs.... Then, after a bit of digging, I am also not seeing the findings of a control group. What is the outcome from the Urine tested from non-smokers/vapors/nicotine users? These people are assumed to be free and clear of the carcinogenic compounds within the bladder? I'll bet no...
