OK, the VG and PG liquid with nicotine that I have has gotten darker. One has yet to be opened, is this normal?

Sort of yellowed correct? It's the oxidation of nicotine. I don't recall reading anything negative about the taste deteriorating when the liquid turns darker, but some people don't like it. I keep the bulk of my nic in the freezer and take some out when I need it.
OK, so it's not bad to use(dangerous)? Never thought about keeping it in the freezer.
Haven't read anything that said it was dangerous, I wouldn't be able to answer that though. However, I'd be willing to bet that as many as half of DIYers are using yellowish colored nicotine (mine turns yellowish when I leave it at room temp for a while. Oxidation supposedly changes nicotine into a different chemical, but I haven't noticed anything significant changing in regards to taste, although you should probably read this thread for some more info:

As far as I know on what I've read/researched. Its not dangerous but depending on how long its been since it was manufactured it may reduce the overall nicotine concentration
