Congress passed a measure that would deny the Drug Enforcement Agency to spend federal money interfering with state approved medical marijuana businesses. Dan Riffle of the Marijuana Policy Project says the key to getting the measure passed this time was the 49 Republicans who voted in favor. Normally, Republicans see medical marijuana as a liberal issue, but now they are beginning to recognize it as a states' rights issue. California Representative Dana Rohrabacher sponsored the measure. Many California marijuana dispensaries and patients have been raided or arrested by the DEA.
