San Francisco has become the first American city to outright ban chewing tobacco at sports venues, which will take effect on Jan. 1, 2016.

Mayor Ed Lee signed the new ordinance into law, which would ban smokeless tobacco or “snuff” from stadiums, and anyone caught dipping will be asked to leave, according to an Associated Press report. Cigarettes and cigars are already banned.

So what do members of the San Francisco Giants think about the ordinance, in a sport where chewing tobacco has been almost synonymous with the pasttime? Players and the team’s manager said they were in support of it.

Giants manager Bruce Bochy said it was a “step in the right direction,” according to the report. Bochy has chewed tobacco in the past, but finally quit by using the help of a hypnotist. Bochy said it’s tough for those who have grown up playing while dipping, and there are “so many triggers” in baseball, but he doesn’t endorse it, and he thinks about his sons in coming to that conclusion.

The Washington, D.C.-based Campaign for Tobacco-Free Kids pushed the ordinance as part of its nationwide campaign. It is backing a more expansive bill that would outlaw tobacco use period, even electronic cigarettes, wherever an organized game of baseball is played in California, according to the report.

Chewing tobacco has been banned in the minor leagues since 1993, but it has remained legal in Major League Baseball. Major league players are unionized, and thus the MLB can’t act unilaterally to ban snuff. However, the current contract prohibits players and coaches from chewing during interviews or carrying it in uniform when fans are at the park.
