Federal Legal Information

The guidance from the U.S. Department of Justice (USDOJ) does not make the use of medical marijuana legal under federal law, and does not create a defense to a federal prosecution for a drug related offense.

On August 29, 2013, the USDOJ announced an update to its federal marijuana enforcement policy in light of recent state ballot initiatives that legalize, under state law, the possession of small amounts of marijuana and provide for the regulation of marijuana production, processing and sale.

The guidance makes clear that marijuana remains an illegal drug under the Controlled Substances Act and that federal prosecutors will continue to aggressively enforce this statute. To this end, the Department identifies eight enforcement areas that federal prosecutors should prioritize.
