After declaring a war on drugs, Philippine President Rodrigo Duterte has now turned his wrath on smokers, passing a sweeping decree to ban public smoking and urging his citizens to help local authorities apprehend offenders.

His executive order, signed this week, and announced on Thursday, outlaws the use of tobacco and electronic cigarettes, in all public spaces, including pavements.

Designated smoking areas must not be within 10m of air ducts, entrances or exits, and are barred in schools, hospitals, clinics, food preparation areas and near fire hazards. The decree also prohibits anyone under 18 from “using, selling or buying cigarettes or tobacco products.”

Violators face a maximum four month prison sentence or a fine of $100.
