An anonymous reader writes: We've known for a while: the War on Drugs isn't working. Scientists, journalists, economists, and politicians have all argued against continuing the expensive and ineffective fight. Now, the World Health Organization has said flat out that nations should work to decriminalize the use of drugs. The recommendations came as part of a report released this month focusing on the prevention and treatment of HIV. "The WHO's unambiguous recommendation is clearly grounded in concerns for public health and human rights. Whilst the call is made in the context of the policy response to HIV specifically, it clearly has broader ramifications, specifically including drug use other than injecting. In the report, the WHO says: 'Countries should work toward developing policies and laws that decriminalize injection and other use of drugs and, thereby, reduce incarceration. ...Countries should ban compulsory treatment for people who use and/or inject drugs." The bottom line is that the criminalization of drug use comes with substantial costs, while providing no substantial benefit.
