A group of 22 medical experts convened by Johns Hopkins University and The Lancet, Britain's foremost medical journal, on March 24 issued a call for the decriminalization of all non-violent drug use and possession, flatly calling the international war on drugs a failure. The paper by the Johns Hopkins-Lancet Commission on Public Health and International Drug Policy (PDF) calls on the world's governments to "move gradually toward regulated drug markets and apply the scientific method to their assessment." Dr. Chris Beyrer, a professor at Johns Hopkins Bloomberg School of Public Health and the senior author of the report, told the CBC: "We've had three decades of the war on drugs, we've had decades of zero-tolerance policy. It has had no measurable impact on supply or use, and so as a policy to control substance use it has arguably failed. It has evidently failed."
