i read somewhere here a few days ago, that someone reported that PG does / can dehydrate the body
hence its very important for vapors to drink regulary water.
however i cant find the thread anymore, can somebody point me to that thread?
Possibly
this thread? Kinda hard to say - if you use the search function and search for 'Dehydrate', you'll get plenty of results.
However, in my opinion - It's not just PG that will dry your throat out. It's simply vaping in general and all of the components involved. You're heating up your throat, adding/subtracting moisture, some (small) form of alcohol is present in the juice; and typically, take deeper breaths (which in my opinion is the biggest factor involved). I have noticed that all vapers will take a much heavier/deeper draw on an e-cig than an analog; and naturally, more air means a dryer throat. Yes, vapor is a form of liquid - but most of that vapor is leaving your throat on the exhale, not lingering. Of course, I have no scientific evidence - just a theory.
