No doubt it will become drug free in the future. Because the president is dedicated to his work also in corruption the philippines is lucky to that kind of president anti government is just insecure in his policy.
I hope so. The early signs are very encouraging. Reports suggest that drug usage has fallen by more than 90% and most of the drug lords have vanished from the scene. It may not be possible to reduce it by 100%, because some of the guys will be always ready to risk their lives for money. But if Duterte could reduce it by a further 5% (90% to 95%), then I would call it as a success.
