Hello - I am pretty new to the vaping world and really like it. Been off analogs for over 3 months and just loving it. I am a little confused. Most all research I have done, everyone seems to claim all we exhale is water vapor - I am no scientist - but it seems to me that may not be correct. Most liquid has PG and or VG, flavor and nicotine. Isnt that what we inhale and should be exhaling? Where is the water vapor from: our body as in the saliva from the mouth? And are not exhaling any of the PG/VG/Nico? I am asking this to compare e-cigs to analogs in any way. I totally agree these are safer than analogs. But I am still confused - does anyone have any information on this......thanks
