Those smokers who are trying to quit need and want to get rid of tobacco with all the risks associated. They have tried time and again to quit cold turkey or using NRT and it was all in vain until they came accross electronic cigarette.
In most cases a good quality electronic cigarette with standard voltage battery and standard resistance atomizer/cartomizer, a device either "look alike" or pen-style, is quite sufficient for them to switch.They don't really need APVs.
Of course, I wouldn't really write this 3-part rant if this is all there's to it.
The hygroscopic nature of Propylene Glycol, an important ingredient in e-juice, tends to cause dehydration. So, make sure you drink more water anyway. Another valid point is that although we can find out and read much on Propylene Glycol, Vegetable Glycerin and other ingredients, there is something we can not read, because we can not find it.
And we can not find it because it isn't there yet .
And that is a study of the long-term effects of e-liquid when ingested the way it is in vaping. The first serial manufacture of electronic cigarettes started in China in 2004. Western enthusiasts have their enthusiasm 2-3 years old, 5 at best. So, there is absolutely no way for us to reliably and exactly know what is going on in the long run, say a decade or two.
Yes, PG is used as a solvent, emulsifier, moisturizer, food additive and so on. It is also used for creating artificial fog in a discoteque. But we don't vape this fog for months and years on a daily basis. PG is used for asthmatic inhalator. But I have yet to see an asthmatic patient vaping it for days and months incessantly!
What we do have so far is evidence from experience of a large number of people who find that switching to e-cigs has improved their overall health. So, we can safely assume that e-cig is much healthier than tobacco cigarette!
However if we don't know the long term effects of vaping a combination of PG, VG, nicotine and flavor(s), isn' t it much more advisable and commonsensical to abstain from things that make us spend a gallon of e-liquid per year instead of 0.5 to 1 liter!
