It's not done much in the way of prevention that's for sure. Look how many are dying from these lethal opioids that are coming from all over? How many lives of kids have been destroyed from gang violence crossfire to gang recruitment to the neighborhoods that are so blighted that drug money is the only way they can see that could make any money? Even the reason the war exists is lopsided: it's not illegal for the harm caused but because the government didn't get their cut. It's just like illegal gambling and casinos: casinos kicked up to their gov masters so they're ok. Some drugs shouldn't be legal of course but they should actually receive government effort in being stopped vs the half assed waiting for a bribe way it is now.
The war on drugs has cost many people their lives, from being killed in drug raids to going to prison. The idea of the drug war is to protect people from drugs, but the end result of it has been to create a police state, in some respects. Too many people die, as a result.
The war on drugs ranks among the most colossal and complete and utter failures of government. It really is emblematic of exactly why government is too big and not effective. The war on drugs only serves to keep union law enforcement employed. Time to end this useless war and let people keep the money they pay for the failure.
It is time for South American Governments to tell the US and UN where they can place their drug war and start standing up for the interests of the people they are supposed to represent. The US is prepared to see poorer countries torn to pieces so they don't have to deal with the conflict on their own territory.
The war on drugs has not been a failure, because some people have been saved by it. Not everyone has been helped, and there are still many addicts out there. But for the few people who have not had access to drugs because of the war on drugs, the policy has been well worth it to them and to their families.
