Evening all. I wasn't sure which forum to post this in, so please feel free to move it if needed.

I'll be flying from SAN into ORD on a connection to GSO next month. Unfortunately, I'm still a smoker. Since I will have a layover of about 2hours, is there anywhere inside ORD that allows smoking? Do I need to go all the way outside? If so, how long would it normally take to get back thru screening in the later afternoon hours on a Sunday?

TIA for the answers. This will be my first trip thru ORD, and I have no idea what to expect.
