Dan Baum has a lengthy article in the latest Harper's titled, "Legalize It All: How to Win the War on Drugs."
Here is an excerpt:
Experiments in alternatives to harsh prohibition are already under way both in this country and abroad. Twenty-three states, as well as the District of Columbia, allow medical marijuana, and four — Colorado, Washington, Oregon, and Alaska — along with D.C., have legalized pot altogether. Several more states, including Arizona, California, Maine, Massachusetts, and Nevada, will likely vote in November whether to follow suit. Portugal has decriminalized not only marijuana but cocaine and heroin, as well as all other drugs. In Vermont, heroin addicts can avoid jail by committing to state-funded treatment. Canada began a pilot program in Vancouver in 2014 to allow doctors to prescribe pharmaceutical-quality heroin to addicts, Switzerland has a similar program, and the Home Affairs Committee of Britain’s House of Commons has recommended that the United Kingdom do likewise. Last July, Chile began a legislative process to legalize both medicinal and recreational marijuana use and allow households to grow as many as six plants.
