Smokers will have to butt out to designated smoking areas outside of the stadium.
Smoking might calm nerves, but fans of both the Baltimore Ravens and Orioles will no longer be allowed to light up anywhere inside the team's home stadiums.
The Maryland Stadium Authority has announced it will prohibit smoking inside stadiums at the Camden Yards Sports Complex. That 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.
A Stadium Authority spokesman said the Ravens will make accommodations for fans by allowing patrons to leave the stadium, smoke in a designated area, and go back inside. The Orioles are expected to announce a similar policy before Opening Day this spring.
