The U.S. Justice Department is moving to make marijuana use a less serious federal crime with a proposal to reclassify the drug as on par with Tylenol with codeine, rather than heroin, according to sources. Under the Controlled Substances Act, marijuana is listed as a schedule one substance, meaning it has a high potential for abuse and no current accepted medical use. The Department of Justice, which oversees the Drug Enforcement Administration, recommended that cannabis be classified as a so-called schedule three drug, with a moderate to low potential for physical and psychological dependence.
