HARRISONBURG, Pa. -- Pennsylvania might join Hawaii in requiring the minimum age for tobacco use to be 21, Philadelphia Magazine reports. The current age for tobacco product purchases in the state is 18.

On Wednesday, state Rep. Vanessa Lowery Brown sponsored House Bill 1628 to change the minimum age to buy tobacco products. “Studies show that the vast majority of those who smoke daily began before the age of 19,” said Brown. “Restricting access to tobacco products until age 21 should lower the smoking rate in the commonwealth.”

Hawaii’s law, which goes into effect January 1, is the first statewide measure to set the minimum age for tobacco purchases at 21. Hawaii included e-cigs in its law. New York City also forbids the selling of tobacco products to those under 21. Four states have set the minimum age for tobacco purchases at 19: Alabama, Alaska, New Jersey and Utah.

Brown’s push has a slim chance of success, given how difficult enforcement would be for those who simply cross the state line to buy smokes. Also, Brown herself is set to go on trial later this year on bribery charges.

Meanwhile, 10 U.S. senators are backing a proposal to limit the sale of tobacco products to adults age 21 and older.
