Seattle joined a list of cities around the country that has banned chewing tobacco at Major League baseball games.
Other cities that have banned chewing tobacco at games are Chicago, New York, Boston, Toronto, San Francisco and Los Angeles. Additionally, California state law prohibits chewing tobacco use at games in Oakland and San Diego.
This means players and coaches can’t chew it on the field and spectators can’t chew it in the stands.
Major League baseball has been urged to ban chewing tobacco. For some odd reason, chewing tobacco use is rampant among ballplayers. The MLB and the player’s union took a somewhat wimpy approach to the issue, banning tobacco use on the field for all incoming players but grandfathering it in for existing MLB players. Which means, eventually it’ll go away, but for the time being you’re still going to see coaches and players chewing on the field.
