Just my
here...I prefer plastic bottles for my nic storage. I buy 100mg PG nic and like a lot of peeps, had a chicken little moment when I thought it was going to be massively regulated (I now have enough at my current nic/consumption level to last me 20 + yrs). The reason why I even considered buying that much is I have the fortune of living in a house with a basement with a large chest deep-freeze in it. The kids have moved out so I've basically replaced the food reserves with ice, the freezer hardly ever runs as I rarely go into it, and if the power goes out, the ice in there should keep me for a bit...but with the plastic bottles I can squeeze the bottles till the nic/PG is just about overflowing and then screw the cap back on (no air) and I date them so I can use oldest to newest. I just cracked open a jug that is over 3 yrs old that I got from VZ, it's clear and no odd smell...tastes fine.
Straight VG and PG are easy to get (in Canada you can buy it off the shelf at a drugstore), I buy as needed.
There's nothing scientific about what I'm saying or doing, but it seems to work.
