Medical Marijuana

Medical marijuana has strong support from voters and health organizations. The federal government, however, has resisted any change to marijuana's illegal status at the federal level. The Supreme Court ruled in 2005 in Raich v. Gonzales that the federal government can prosecute medical marijuana patients, even in states with compassionate use laws, and several medical marijuana dispensaries in California have since been subject to Drug Enforcement Administration raids.
