SPRINGFIELD, Ill. – Illinois convenience stores and vape shops are asking Gov. Bruce Rauner not to sign a bill that would increase the state’s tobacco buying age to 21, the Chicago Tribune reports. Such a law would only harm retailers and push younger consumers to buy tobacco on the black market, online or in a neighboring state, retailers said.

Bill Fleischli, executive vice president of the Illinois Petroleum Marketers Association and Illinois Association of Convenience Stores, said the bill likely will boost the traditional and electronic cigarette black market. He added that 87% of the state’s c-stores are located within 50 miles of a border, while 19% are located within 10 miles of the state line. Teenagers crossing the state line to buy tobacco also will buy their snacks in border states too. “Very few people buy one item at a convenience store,” he said.

That’s a fear of Curt Adams, president of Illinois Ayers Oil Co., with a store in Quincy near Missouri. “They can cross borders,” Adams said. “This needs to be a federal bill. With this happening in just Illinois, this bill is not a solution.”

Two years ago, Chicago enacted an ordinance to raise the tobacco buying age to 21. Twenty-three other Illinois areas have also increased the tobacco purchase age to 21. Other states, including New York, have debated a higher minimum age for tobacco purchase. Currently, only California, Hawaii, Maine, New Jersey and Oregon have passed laws making 21 the legal minimum age for buying tobacco.
