DAVAO City mayor and vice presidential aspirant Sara Duterte-Carpio on Wednesday claimed she tested negative for drugs.

"Today, I took a drug test that yielded negative of any illegal substances. This test, I took voluntarily upon the request of my Uniteam partner, Senator [Ferdinand] Bongbong Marcos, to support the call for transparency as aspiring public officials seeking the trust of our fellow Filipinos," Duterte-Carpio said in a statement.

"Uniteam BBM-Sara's stand against illegal drugs is united and unequivocal. This can be seen from both our negative tests as well as our common stance against the proliferation of illegal drugs and the need for effective measures of prevention, rehabilitation, and enforcement," she added.

Marcos himself tested negative for drugs.
