Starting in March, smoking won’t be allowed in either Camden Yards or M&T Bank Stadium, reports WTOP:

The Maryland Stadium Authority will prohibit smoking inside stadiums at the Camden Yards Sports Complex.

A spokesman for the authority said Monday that the rule will take effect March 4 and will apply to all games and events held within Oriole Park at Camden Yards and M&T Bank Stadium.

Previously, there had been designated areas within the stadiums where patrons could smoke.

Smoking isn’t allowed at Nationals Park, while it is only allowed on ramps at RFK Stadium. Most of FedEx Field is off-limits to smokers, though they can sneak a smoke in the Club Level enclosed concourse, the Montecristo Club Cigar Bar and two smoking decks located near gates A and E.
