The Tempe City Council is scheduled to vote Thursday, Oct. 26, on whether to raise the legal age to buy tobacco to 21.
Flagstaff and Tucson already have similar age policies.
But first, the council will hold a public hearing on the proposal that would create a city registry of tobacco retailers that pay yearly license fees.
If the ordinance passes, those caught selling tobacco to underage people would face progressive discipline via fines, license suspensions and permanent revocation. Four-time offenders would have their license revoked.
Flavored tobacco products would not be banned by the ordinance.
