The US Food and Drug Administration is reviewing the medical evidence surrounding the safety and effectiveness of marijuana, a process that could lead to the agency downgrading the drug's current status as a Schedule I drug, the most dangerous classification. "FDA conducts for Health and Human Services a scientific and medical analysis of the drug under consideration," FDA Press Officer Jeff Ventura said. "HHS then recommends to DEA that the drug be placed in a given schedule. DEA considers HHS’ analysis, conducts its own assessment, and makes a final scheduling proposal in the form of a proposed rule." (See also: Scheduling in the international drug control system)
