In January 2008, the American College of Physicians called for a review of cannabis's Schedule I classification in its position paper titled "Supporting Research into the Therapeutic Role of Marijuana" It stated therein: "Position 4: ACP urges an evidence-based review of marijuana's status as a Schedule I controlled substance to determine whether it should be reclassified to a different schedule. This review should consider the scientific findings regarding marijuana's safety and efficacy in some clinical conditions as well as evidence on the health risks associated with marijuana consumption, particularly in its crude smoked form."
