PG vs. VG

[zer0xity]

Other than the fact that VG tends to produce more vapor while muting flavor and makes for a thicker juice while PG is thinner and doesn't mute flavor as much while producing less vapor - is there any substantial difference between the two or is it just a matter of preference? I've seen some posts where people even tout how long they've been off PG. Any health risks or the like to be aware of?

Thickness - VG is thicker

And some ways of vaping do not work well with thick juices

I won't use any more than 20% VG in my stuffing-type cartos

Vaporized PG is used for inhalation therapies in hospitals, even for lung transplant patients.

And PG lets through nicotine's TH and irritation best, VG dulls/smooths both TH and irritation

My gut tells me that the flavorings are the worst thing we vape.

I know some people seem to have allergies to the pg. I have vaped both and like both. My sweet spot seems to be 2/3 pg to a 1/3 vg. Time will tell if one is better or worse for us.

I am one of those people. I broke out in a rash, small flat red spots all over my chest. (lungs area) It goes away after a couple of days of not vaping. Looking into VG now. Will it not work well with 808's? Too thick for those carts? I am afraid to use any PG anymore.

You can thin it with distilled water or grain alcohol. Personally, I don't use filler carto's. Since I saw my first Clearo, I haven't used anything I can't see through. JMHO

I use 100% VG juices in my Volt, Boge and Smoktech cartos regularly--haven't noticed any problems. Sometimes I think in my mind I should wait between puffs for the juice to wick down to the coil, but sometimes I don't think about it and everything seems to work alright. I don't mind PG but there's something about PG-heavy juices that just give me a sharp chemical taste and TH.

80% VG w/ 20% H2O works well in attys, CE2's and dual coils.

The waiting between puffs thing makes sense.... If I chain vape a heavy VG juice.... every here and again I will get a dry wick hit...matter of fact I did it this afternoon on KBV strawberry pie 60%vg.... thought I ruined my carto for a bit, but the burnie went away in time.

Re thickness - it depends where you get the juice. Some vendors thin their VG juices to improve flow and others sell VG juices so thick you can barely squeeze them out of the bottle.

I like the thick one. 100% Glycerine.

While it's true That PG produces an absolute TON of vapor, I'm definitely not a fan of it, unless it's a proper VG to PG mix, and obviously flavor. PG alone just kills the flavor Entirely, and in some cases creates a bad after taste, for me that is... I recently started using dual coil cartomizers, and the vapor that it produces even with PG is amazing, but I'm also hittin at roughly 1.6 ohms, so that would explain it. I believe it does fall under preference tho, but taste is the biggest thing for me... what I'm not understanding tho, is why do some PG juices vape better than other PG juices, even when they're all mixed the same way?

PG makes less vapor, VG makes a ton of vapor

But I think PG wicks faster, moves through carto stuffing faster, etc

Not what I've experienced.

i used to mix 70 pg 30 vg but now im mixin 50 50 and couldnt be happier

Justinking -- perhaps you're mixing the terms VG and PG? VG is the massive vapor producer, though it tends to mute flavors, and is known to leave some people with a bit of aftertaste or oily sensation.

As to variation in liquids, there are huge differences in what different people use, they really aren't all mixed the same way. For example, some "VG" nicotine base has a significant amount of alcohol in it to thin it, make it easier to work with, be much thinner than a true "pure" VG liquid, or a VG liquid that has been thinned with distilled water. The flavorings used also have large variation, depending on the source for them, and may contribute greatly to how thin the resulting liquid is -- some of the non-PG flavorings use a decent amount of alcohol as a carrier, while others may get away with mainly VG (depends on solubility).

I stick with just straight PG, it gives me the nic, TH, and flavor, I don't need to fill the room with fog every time I exhale.

I love the thick, smooth vapor from VG, and put up with the thick juices to get it. That said....

Like Emus stated, I'm more concerned with the flavorings that are used.

Some mixes just irritate the lungs and throat, and that is probably not a good sign. Others smell like a terribly pungent perfume. I don't think I have to explain why that's a turn off.

PG vs VG, it would seem that PG is a known entity, and probably completely safe to vape. VG isn't really as well tested, but it sure irritates me less. The flavors are known or unknown for safety, and vendors choose to err for safety or not at all, completely at their own discretion, which is my only real cause for concern about the industry as a whole.

+1 on that! I vape at 6 volts, so I don't want any more vapor than what's produced with pg. I think vg has a weird aftertaste, so me and the Mrs. are 100% pg juices. I do enjoy some premixed juices that use some vg, but I'm almost certain I'd like them better without the vg. I'm 100% sure, the pg wicks better, and fills cartos faster.

I understand...but it sure is fun blowing those O's
