ST. PAUL - Owners of a retro soda shop in Minnesota have been warned by city inspectors to quit selling their popular candy cigarettes, bubble gum cigars, and Big League Chew, CBS News reports.

St. Paul inspectors have threatened to issue a $500 fine if Lynden??s soda fountain is caught selling the novelty items again, which violates a city ordinance barring the sale of candy smokes and cartoon character lighters.

Inspectors were tipped off by a complaint about the presence of tobacco-themed candy at the mom and pop store.

According to store owner Tobi Lynden, the candy cigarettes were best sellers and mostly purchased by adults.

"We're a tiny little soda fountain shop that specializes in vintage candies and vintage sodas," Lynden said. "We never had any issues with it. People were always happy to see them."
