An attempt by two California counties to ban the use of medical marijuana has been rejected by the U.S. Supreme Court, which refused to hear a case brought by San Diego and San Bernardo counties.
They argued that the federal law outlawing marijuana should take priority over a California law that allows the use, cultivation and possession of marijuana for medical purposes, Agence France Presse reported.
The California law was adopted by referendum in 1996. Twelve other states have similar laws.
San Diego and San Bernardo lost twice in lower courts and again on appeal. The California Supreme Court refused to take up an appeal. The U.S. Supreme Court's rejection means the case is now closed, AFP reported.
