I didn't think about it at the time but I had a carto that was filled with juice that I had set aside for about 2 weeks. Decided to vape on it a few days ago. Suddenly I have a raging sinus infection. Who knows where the infection came from but I started thinking... should I have tossed the carto after sitting for so long and filled a new one with the juice? What is the best way to preserve juices? How long can I keep juice before it needs tossed? I usually vape with clearomizers which I love especially my T3S. I wonder, also, how often I should clean the clearos? Never had any problem before now and can't definitively connect the carto to my sinus infection but just got me wondering. Any insight out there?
