The new law on the Big Island that raises the tobacco-buying age to 21 goes into effect on July 1.
The legal smoking age is still 18. But, the law penalizes retailers who sell tobacco products, like cigarettes, to use under 21. Electronic cigarettes are also affected.
Those who turn 18 before the end of June are exempt.
The Hawaii Tribune-Herald reports businesses must display a sign stating the new law. They also say most of their customers are above the age of 21.
