First U.S. marijuana cafe opens in Portland

The United States' first marijuana cafe opened on Friday, posing an early test of the Obama administration's move to relax policing of medical use of the drug.

The Cannabis Cafe in Portland, Oregon, is the first to give certified medical marijuana users a place to get hold of the drug and smoke it -- as long as they are out of public view -- despite a federal ban.

The creation of the cafe comes almost a month after the Obama administration told federal attorneys not to prosecute patients who use marijuana for medical reasons or dispensaries in states which have legalized them.

About a dozen states, including Oregon, followed California's 1996 move to adopt medical marijuana laws, allowing the drug to be cultivated and sold for medical use. A similar number have pending legislation or ballot measures planned.
