Guess I am brain dead today but I can't remember how long a bottle of juice will last I am cleaning out my juice cabinet and have some juice over a year old, so can they still be vaped or do they have to be trashed? I don't care if the nic is gone or not, in fact I have some with way to high nic level for me now and will add VG &Pg if I can still use them....Thanks in advance for the help
