pg or vg - what's the difference

[costeve]

I'm a newbie.
I've seen some people refer to "pg" and "vg". It sounds like they're talking about a type of juice used in the ecig device. Can somone explain to me what "pg" and 'vg" means - what the difference is between the 2.

And apparently, some people the "vg" works better than the "pg".
Why?

I need to understand this before I buy anything.

Thanks

Costeve, PG is Propylene Glycol – used in food flavorings, cosmetics, the artificial “smoke” at rock concerts, and, yes, antifreeze. [No, we are not inhaling antifreeze (shudder), just one of its ingredients.] VG is Vegetable Glycerin – more syrupy, and derived from veggies.

What follows here is taken from Part 3 of my WWV Illustrated Guide:

PG vs. VG

The nicotine and flavoring are the ingredients that make our world go round, but what gets vaporized is the base liquid. In most cases, this is PG. But some people are allergic. You’ll know soon enough and it’s usually nothing serious. Symptoms vary, but can include: dry or sore throat, muscle cramps and aches, ........, night sweats, and rash (usually not all at once or in the same person, thank goodness). If you experience any of these:

1. Consult with your doctor (I ain’t no MD), certainly if it is anything other than mild discomfort and/or it continues for several days. [Sounds like the back label of a bottle of over-the-counter meds, doesn’t it … but there is a good reason they do that, you know.]

2. Explore the Health, Safety and E-Smoking forum, especially its most-read thread: A List of Common Symptoms when E-smoking. ß Recommended for all new vapers. There are lots of “interesting” symptoms (some of them really nice) often associated with stopping smoking and starting vaping, only a few of which are PG-related.

3. Try VG-based liquid … or PEG (Polyethelene Glycol) ... or ECOpure (brand name of a UK-manufactured mixture consisting of VG, ethyl maltol, and nicotine … and no PG, and purported to be very pure).​

Even if you are not allergic to PG, you might prefer VG or those others. Conventional wisdom is that PG packs more flavor and throat hit, but VG generates more vapor. [When I mix my own juice, I use both.]

There is a lot more information about PG and VG here on ECF, Costeve, but the standard ECF Search function rebels against terms less than four characters. So let me offer a search tip: in the small Google Custom Search box in the far lower left of most ECF pages, type in: +pg +vg. That yields many ECF threads, which appear to be directly on point.
