PORTLAND, Maine – Adults between the ages of 18 and 21 will still be able to smoke in Portland, but will soon not be able to purchase cigarettes to do so, the Bangor Daily News reports. The Portland City Council approved an ordinance raising the minimum tobacco-buying age to 21, but kept the legal smoking age at 18.

The move makes Portland the first Maine city with such a tobacco-buying restriction, following a nationwide trend to raise the age requirement of tobacco purchases to be in line with alcohol purchases. Currently, more than 100 localities, including Boston, Chicago and New York City, and two states (California and Hawaii) require adults to be 21 to buy any form of tobacco. Most of those laws also include e-cigarettes.

Portland retailers selling tobacco products vehemently opposed the proposal as an unwarranted restriction for legal adults. The new rules would encompass tobacco products in all forms, including electronic cigarettes. City Council Member Ed Suslovic, chair of the Health and Human Services Committee, said the rule would become law 30 days following the vote on June 20.

Meanwhile, cigarette smoking among high school students dropped to 11% in 2015, according to a new Centers for Disease Control and Prevention survey. Read more about increased age limits for tobacco purchases in the March issue of NACS Magazine.
