Marijuana use should be decriminalized and federal officials should reclassify cannabis as a less dangerous drug to spur vital medical research, the leading group of U.S. pediatricians recommended Monday. In an update to its 2004 policy statement on pot, the American Academy of Pediatrics (AAP) also recognized marijuana may be a treatment option for kids "with life-limiting or severely debilitating conditions for whom current therapies are inadequate." Sharon Levy, chair of AAP's committee on substance abuse and assistant professor of pediatrics at Boston Children's Hospital, is one of the statement's coauthors.
