Has anyone had any problems getting an ecig past airport security? I have a trip coming up in a week and this will be my first flight with an ecig. My trip isn't long so I wasn't planning on checking any baggage and was wondering if anyone has ever been held up going through the security gate. I once had to carry on a barcode reader and ended up being detained for almost an hour while the inspected it. I don't want to repeat that again...
