I asked earlier if there’s any place inside the airport where you can smoke without having to go all the way back out to security and outside so I said yes but where in the airport I’m near B Delta

No, you cannot smoke anywhere beyond security.

Not once you're past security. I have only seen a room by the main terminal entrance doors.

They are correct... There is no smoking area near the gates.

No you have go outside

You can't . You have to go out through security and back in again
