The Philippine Drug Enforcement Agency (PDEA) in Region 6 said the camp of presumptive president Rodrigo Duterte has already asked them to submit a list of drug personalities in Western Visayas.

According to PDEA-6 Regional Director Paul Ledesma, the request came from a retired Armed Forces of the Philippines general who could become part of Duterte's cabinet.

The Western Visayas Region, located in Central Philippines, is composed of six provinces: Aklan, Antique, Capiz, Iloilo, Guimaras and Negros Occidental.

PDEA, as the lead government agency in combating illegal drugs, is mandated to "arrest and apprehend as well as search all violators and seize or confiscate the effects or proceeds of the crimes as provided by law; take charge and have custody of all dangerous drugs and/or controlled precursors and essential chemicals seized, confiscated or surrendered to any national, provincial or local law enforcement agency," among others.

During his campaign, Duterte vowed to wipe out crime in three to six months if elected president. Duterte's crusade is also centered on the eradication of illegal drugs, vowing to kill drug pushers, even his his own children if proven they are into narcotics.

Earlier this week, Duterte's camp also said the president-elect is planning to implement a nationwide liquor ban, which prohibits buying and selling of alcoholic beverages during 1:00 am-6:00 am, to help curb criminality.

"The reason he has this liquor ban (in Davao) is because we have to work the next day, all the (restaurant) staff have to work, as well as the customers," Duterte's spokesman, Peter Lavina had said.

"This has nothing to do with denying us of our freedoms," he said, adding people were not prohibited from drinking in their homes.

The proposed ordinance was welcomed by some but was frowned upon by some businessmen.
