It's not possible, do you remember during the campaign period of Mr. President? He said, it will just take 3 to 6 months to free drugs, then approximately after a year he said that it may take another year for his term to finish it but apparently, lately he said that it will never gonna happen ,he said 'yung ibang bansa nga hindi kaya tayo pa kaya?' "Other Countries cannot do it, do you think we can?".
For me, i think, Mr. President has never been true to his words, he should really resign because after 6 months from the start of his term, Philippines is not yet drug free, but over all i admire him for his guts to make this project but i really want him to stay true to his words.
It is not possible to eliminate 100% of the illegal drugs, due to the huge population and complex geography. But you need to appreciate the results. The crime rate has fallen and the drug users are no longer seen on the streets. When someone does something good, please learn to appreciate him. I am not a Filipino. I am not even from the ASEAN. Even then, I appreciate Duterte for his courage to take on the drug gangs.
