The probation of drugs in US is bringing much damage to neighboring supplier countries south of the border such as Mexico where the real costs of the drugs are felt in human lives. The war on drugs is exactly the same problem as we had during the alcohol probation in the 1930s, maffia like Alcapone taking over Chicago, if the state legalizes the drugs there is better opportunity to treat and help the drug users. As long as there are drug users there will be drug suppliers.
