FLAGSTAFF, Ariz. — A small northern Arizona city has become the first in the state to raise the age to buy tobacco and vapor products from 18 to 21.

A group of students from Mingus Union High School in Cottonwood worked to draft the city ordinance that goes into effect in June.

The City Council voted unanimously for it May 3. The ordinance regulates products like smoking and chewing tobacco, cigars and electronic cigarettes.

City manager Doug Bartosh says the students presented compelling arguments on the health impacts to people who start smoking at a young age.

The National Association of Tobacco Outlets, Inc. had urged the council to reject the change.

Two states and about 140 local jurisdictions across the country have raised the age for such purchases.
