PG, VG, and Nicotine. Shelf Life?

[llmercll]

Hi all,

I've been using the same PG and VG for close to 2 years now and am just wondering what the consensus is on whether or not it should be replaced after this time? I've also been using a bottle of nicotine/pg solution for the same amount of time.

They've been kept in a cool, dark, dry cupboard, but would just like to be sure before negativly affecting my health.

thank you!

I know that some PG and VG bottles have expiration dates on them, but I don't see why they should not actually last much longer, if kept in a cool, dark place. Nicotine can be frozen. There are many threads on here about nicotine lasting many years in the freezer.

I vape entirely too much to have this concern. LoL

Thank you very much for the replies!

Yeah, I purchased a bit too much for my vaping needs, but I figured that opening the bottle all those times, sticking my needle in, etc might have degraded the quality or introduced contaminants. Being that VG and PG is so cheap I will probably just buy some fresh stock (in smaller quantities) from wizard labs or another reputed dealer.

I've also been told that nicotine does convert to nicotine oxide over time. I'm unsure of how bad that is, however.
