"The U.S. Supreme Court handed medical marijuana patients and advocates a resounding victory on Monday, refusing to hear a case brought by San Diego County, which has long chafed at implementing statewide medical marijuana laws. The courts have made clear that federal law does not preempt California’s medical marijuana law and that local officials must comply with that law,” said Joe Elford, chief counsel with Americans for Safe Access (ASA), a national medical marijuana advocacy group with a large presence in California. “No longer will local officials be able to hide behind federal law and resist upholding California’s medical marijuana law."
