How do PG and VG compare?

[md121641]

I have seen many references to PG and VG liquids but no mention of the differences.

I know that VG is much thicker than PG but what about the amount of vapour etc.?

I am researching things for my step son who is unfortunately mentally disabled, and as a result he is very into 'lots' of anything [ie. vapour], but not good at determining the difference between 2 things for himself. I have bought both pure VG and pure PG juices but he has so many problems just keeping the cigarettes working (overheating atomizers and dirty screw threads mostly) that he has a hard time doing a real apples to apples test.

He often complains that the smoke is harsh - I think due to overheating - so might that problem be reduced by using PG, VG or a mix?

Any help would be appreciated.
Thanks ... Mike

Mike, Good on ya to be researching this on behalf of your son. I'll try and provide what answers I can, and hopefully a veteran can add more to it.

VG is thicker than PG.

VG also produces more vapor than PG.

The harshness that your son is experiencing could be due to a number of reasons.
1) Dry atty: The atty is not getting enough juice, and he is vaping "burnt" matting, or filler.
2) High PG concentration: Juices that have a high PG content 90+ % could account for harshness or "throat hit".
3) High Nicotine count: Juices with Nic counts of 24 or more could also account for harshness.

If I had to summarize and provide a suggestion, I would say get your son a juice that is higher in VG, with a low nic count (maybe 12 or 18).

Hope this helps. Best of luck!

The simple explanation is this:

VG is thicker, adds a little sweetness and produces lots of vapor.

PG is thinner, produces a stronger TH, but produces less vapor. It will also let the flavor come through better than VG, which can mask some flavors.

What He said. PG makes better throat hit and VG makes better vapor.
