"Although I'm not in a position to judge anyone on this issue, I am willing to undergo drug test anytime and anywhere," Pacquiao said.
In a statement, he also urged his fellow presidential bets to do the same.
"Mas maganda kung hair follicle test para mas sigurado (It's better if it's a hair follicle test to be sure)," he said.
On the other hand, he stated that mandatory drug test must be required for anyone who wants to work in government, elective or appointed.
"This will be a requirement in my administration without prejudice sa mga na-rehabilitate at talagang iniwanan na ang bisyo. Lahat naman po ay may karapatan na magbagong-buhay (Everyone has the right to change)," he said.
Fellow presidential aspirant, Sen. Christopher "Bong" Go made a similar statement and stressed that like what he said in the past, if he will be asked to undergo a drug test, he will do so anytime, anywhere.
"Kahit hindi naman required ito ng batas, willing akong mag-volunteer na magpa-drug test. Ito ay para maipakita natin sa mga botante na fit for public service ang mga tumatakbo (Even though this is not required by the law, I am willing to volunteer myself to get a drug test. This is to show the voters that candidates are fit for public service)," he said.
He added that is is the right of every Filipino to know that their candidate is clean before they make their decision.
