I hear you.
The truth is, we don't really know the long-term health consequences of vaping. Yes, I know that Dr Homunculus reckons it's at least 95% more healthy than freebasing Golden Virginia but I also know that doctors were recommending smoking as a cure for all ills not so long ago.
Nicotine seems to have been studied a lot more than PG, VG and flavourings in relation to human consumption and appears to be relatively harmless. It seems sensible to me then to maximise your intake of relatively safe products and minimise your intake of unknowns. Max your nic, minimise your overall liquid intake.
It's almost like all us ex-smokers have been brainwashed to believe that it's nicotine that's the problem with smoking and there's this kind of competitive race to get down from 24mg to 3mg as soon as possible. It doesn't seem to matter that people are now taking 20 to 30mls of liquid into their lungs each day because IT'S ONLY 3MG!!
Not saying I'm right and everybody else is wrong, I just think it's something else to be considered.
