Every venue has it's own regulations. Call your local stadium or visit their website to see what their rules are on smoking.

I'm not saying this because I am against smoking; in fact, I smoke too. But smoking in a crowded place is aggravating to most people. Have you ever gotten home from a crowded event and found that someone has burned a hole in your new coat? With all the yelling and jumping around that goes on at football stadiums, it's not a good idea.
