How Long?

[louis]

If this topic has been discussed somewhere else just point me to it.
I am wondering how long e-liquid is good to vape?
Not only the PG/VG but also the Nic & Flavoring?
I use FA flavoring & nic I get from ecigexpress.com.
I also have some juice that is over 12 months old that I haven't vaped up yet.
Some of the FA flavoring has turned fro clear to a light brown color, but still smells the same as when clear.
Just don't want to be vaping something that will do anymore harm to my lungs.
See I quit after 48 years of analogs. WOW.

Keep on Vapin',

You would need to ask the individual manufacturers, nut it certainly can't hurt to store them in a cool, dark place

This would probably depend on a few factors.
Quality of nicotine,
Quality of the PG/VG.
Ratio of PG/VG.
How the liquid was stored (plastic vs glass vs amber/colored glass).
What was the temperature the liquid was stored at, etc.

The more brown the liquid is, the more oxidized nic it will (USUALLY) contain (minus any dark flavorings. for example.. Vanilla and chocolate flavorings can be pretty dark in color and wouldnt have anything to do with oxidized nic).

In general the older your mix, the more oxidized nic you'll have. This can effect flavor, etc.

I *Think* the general thought is to vape your mixes within 6 months to a year. *HOWEVER* Some say the more aged some flavors are the better they become. I do not know my mixes don't seem to last longer than 3-4 months.
YMMV (Your Mileage May Vary). Take my words with a few grains of salt.
