The bill includes an amendment that prohibits the Department of Justice — which includes the Drug Enforcement Administration — from using funds to interfere with state medical marijuana laws. A similar amendment has been offered seven times in Congress, failing in 2003, 2004, 2005, 2006, 2007, and 2012. The House finally approved it in May when it was offered by Rep. Dana Rohrabacher (R-CA) as an amendment to the Commerce, Justice, Science, and Related Agencies Appropriations Act.
