I chew and as far as I know it hasn't been banned anywhere yet.
Just wait 'til the smoke nazis start whining about second hand spit.
I chewed when I went to see a St Louis Rams game versus the 49ers a couple years ago. The new Rams facility was smoke free.
Until halftime at least that is. After the halftime show there was so much smoke in the dome that my eyes were watering! Needless to say ( for this reason along with 7 dollar beers and 5 dollar hot dogs) I have not been back.
LOL
Makes swapping chew sound bad...
