MANILA – President Rodrigo Duterte on Friday brought up again his controversial use of pain reliever Fentanyl.

In a speech in Davao City, Duterte admitted that he took more than the required dosage of the pain reliever because apart from easing his burden, it also made him feel like he was “on cloud nine.”

“Iyung Fentanyl, the doctor stopped it because he got mad. I’m supposed to cut it into four pieces. Eh there was a time na 'yung buo nilagay ko because more than just the disappearance of pain, you feel that you are on cloud nine. Para bang everything is okay with the world, nothing to worry about,” he said.

Duterte has been criticized for casually talking about his use of the pain reliever, which some experts have described to be potentially addictive.

Duterte had to take Fentanyl after a motorcycle accident when he was 68 years old.
