I recently served as a juror in a federal case in downtown Dallas that lasted for 5 days. I carried 2 KGO batts with Kanger T2 tanks, (each filled with a different flavor and strength juice), in a zippered case in my purse every single day. Day 1, after x-raying my purse, I was asked to remove the case and let the deputy examine what was in it. I did and he looked it over and asked me what it was. I explained, he nodded and smiled - and that was it. I had no issues other than that.
Every smoke break, I was outside with the cigarette smokers, vaping my face off, and when it was time to deliberate, I even vaped in the deliberation room with no problems.
