Thanks op and others, thanks POTV and thanks to the search bar ( was about to post...no need ).
I have plastic bottles in the freezer unopened, plastic in the fridge unopened, and plastic in the cupboard steeping or unopened.
I am worried about a possible ban/4mg limit coming into force, but no way will i revert to smoking again, and no way will i stop wanting and using nicotine: so i am stocking up. And i suddenly thought, what if i was completely wasting my time because of spoilage.
I think i may only buy plain nic base in the future for storage....flavours will always be available easily, sweeteners etc, and of course vg and pg. But i LOVE some of the premixed. I think maybe flavoured is bound to spoil faster than plain. And i did not think about plastic being leached into my juice...but maybe the fridge and freezer will limit that, and stuff in the cupboard doesn't stay more than a week or two.
Thanks again POTV people.
