JUPITER, Fla. — Chew and rue.

Mayor Bill de Blasio may sign a bill next week that would ban smokeless tobacco at ticketed sporting events, which would include games at Citi Field and Yankee Stadium. Fans and players would be affected.

“This is going to make a lot of guys not too happy,” one Mets player said Thursday.

Smokeless tobacco bans already have been enacted in Chicago, Los Angeles, San Francisco and Boston. Fines could be similar to those for smoking in prohibited areas in New York.

Curtis Granderson said players and fans should receive an explanation from city officials if the ban is enacted.

“Does that mean a fan at the game will get a citation or something, whether another fan acknowledges it and calls the police or the helpline?” Granderson said. “If a security guard or police or unmarked sees another fan doing it, do they do something? If you see a player doing something, do you give him something, during the game, after the game? It will be interesting to see what the definition is.”

Granderson said substitutes for smokeless tobacco — such as caffeine and mint — have been discussed for players.

“There’s all these other alternatives — it will be made available for them,” Granderson said. “At the same time, a player that chooses to do it and has done it for a long period of time, if told not to do it, he may.

“I don’t do it. I know players and non-baseball players that do it, whether it be habit-forming or certain times, hunting, driving, male and/or female that have used it, so it’s not just a baseball thing. Sometimes you get into it, it becomes a habit and it’s hard to contain a habit.”

The chewing tobacco ban is going before the City Council’s Health Committee on Monday. It could be passed Tuesday by the full council, but as of now it is not on the calendar. It would go into effect immediately after being signed by the mayor.
