CHICAGO — Monday is the last day Chicago baseball fans and players will be able to chew tobacco at the ballpark.

A new law banning all smokeless tobacco products at Wrigley Field, U.S. Cellular Field and all other sporting arenas goes into effect Tuesday.

Under the measure, ballparks and sporting arenas are required to post signs banning the use of smokeless tobacco in all dugouts, bullpens, training and locker rooms, press boxes, television and radio broadcast booths and bathrooms.

Violators face fines of not less than $250 for the first violation, $500 for the second violation and not less than $2,500 for each additional violation that occurs within one year of the first offense.

By passing the prohibition, Chicago joins Los Angeles, San Francisco and Boston in outlawing smokeless tobacco use at all ballparks and sporting venues.
