The scientists compared three situations:
1. Smoking a conventional cigarette
2. Smoking and nicotine ecigarette
3. Smoking a nicotine-free ecigarette
4. Inhaling through an ecigarette without a liquid cartridge (i.e., breathing normal room air)
Conditions 1-3 all reduced exhaled nitric oxide by about the same amount.  There was no effect of condition 4.
What this means is that the ultrafine particles in the ecigarette aeorsol (not the nicotine or something special about cigarette smoke aerosol) is what is causing the decrement in lung function.
This is a really important finding because it shows, at least for this important biological measure of the effects of using ecigarettes on lungs, they are no different than cigarettes.
