The flavors used in our juices are the same stuff in all kinds of foods available commercially and have shelf life that pales in comparison to most perishables. PG and VG are solutions used in most of the stuff we consume every day.
That being said, I doubt they have any problems other than the bottles being dusty. I could be completely wrong but you won't now until you try them out (and neither will the rest of us). I say give them a shot and then give us some feedback after you get back from the ER...

JK...
Vape On!
