TRENTON, N.J. – New Jersey has become the latest state to change the tobacco buying age to 21, AOL.com reports. Gov. Chris Christie signed the new law on Friday. “By raising the minimum age to purchase tobacco products to 21, we are giving young people more time to develop a maturity and better understanding of how dangerous smoking can be and that it is better to not start smoking in the first place,” Christie said in a statement.

New Jersey’s law applies to all tobacco products, including electronic cigarettes. The new law will go into effect on November 1.

Meanwhile, merchants are disappointed about the change, given that neighboring states will still sell tobacco products to those between the ages of 19 and 21, WFMZ-TV reports. “It's going to be a negative business-wise,” said Sal Cassar, owner of Towne Market in Phillipsburg, N.J. “There's no two ways about that.”

Cassar estimated that customers between the ages of 19 and 21 buy around a third of his tobacco sales. “You don't only lose the cigarette sell, [you also lose] any other associated product that the customer was going to buy,” he told the news source.

Meanwhile, in Maine, Gov. Paul LePage vetoed a bill that would have increased the state’s tobacco buying age to 21, the Press-Herald reports. “I believe that at 18 they are mature enough to make a decision and I’m tired of living in a society where we social engineer our lives,” the governor said of his veto.
