Philippine President Rodrigo Duterte, who is under fire for his deadly war on illegal drugs, is planning to impose a nationwide ban on smoking in public before the end of October.

Paulyn Ubial, the health secretary in Mr. Duterte’s cabinet, said on Tuesday that she hoped that the president would sign an executive order before the end of October that would ban smoking in public.

Paulyn Ubial said Duterte wants a 100 percent smoke-free environment in public places similar to Davao, the southern city where he was formerly the mayor.

The measure would restrict smoking to designated outdoor areas away from the public, and would include e-cigarettes as well as traditional cigarettes, cigars and pipes.
