(CNN) San Francisco will become the first US city to effectively ban e-cigarette sales, after the city's board of supervisors unanimously voted in favor of an ordinance Tuesday.

The ordinance says "no person shall sell or distribute an electronic cigarette to a person in San Francisco" unless that product has undergone premarket review by the US Food and Drug Administration. To date, none have.

This includes sales in brick-and-mortar stores, as well as online sales shipped to a San Francisco address. The ordinance also applies to flavored tobacco products in addition to e-cigarettes. The measure does not ban the use of vapes among people 21 and older.

"This is a decisive step to help prevent another generation of San Francisco children from becoming addicted to nicotine," said City Attorney Dennis Herrera in a statement, following the vote.

The measure now heads to Mayor London Breed's desk. In a statement Tuesday ahead of the vote, she expressed her support.
