Argument from authority? Is that the best you can do? Those "professionals" don't have a great track record, which is why drugs are still a huge problem.
So I repeat my question: how are things working out in the Philippines? Are the harsh policies being pursued doing a good job of decreasing the drug problem? If they are, perhaps we can think about adopting aspects of those solutions while leaving out some of the more problematic aspects such as extrajudicial executions.
In the eyes of most of the rest of the world the policies in the Philippines are doing a good job of slaughtering citizens for morally dubious causes. The drugs are being fronted as a way to usher in dictatorial authority for the state and corrupt criminal elements.
Drug use is no different from any other vice, and the nature of addictive behavior is that most people will find some object to attach themselves to if you removed all drugs from the picture ( perhaps it would be human trafficking or gambling, both of which are widespread ) essentially what the people have done is shown that by being presented with a present danger they will willingly give over the very decency that allows a society to function. So no even if mass slaughter did manage to end the drug problem in the Philippines there is no way it should be accepted anywhere else, because it's an inhumane policy.
