San Francisco officials say cigarette maker Philip Morris has dropped its lawsuit challenging the city's prohibition on tobacco sales at pharmacies.

The announcement Thursday by the city attorney's office follows a federal appeals court ruling denying the company's request for an injunction that would have kept the city from enforcing the year-old law.

City officials say the ban makes sense when tobacco products are unhealthy and drugstores are supposed to promote health.

The city still is defending the law in a separate lawsuit brought by the Walgreens drugstore chain. A Superior Court judge dismissed that case, which is now on appeal.
