In May, the Department of Justice issued a notice of proposed rulemaking (NPRM) that proposed the reclassification of marijuana from a Schedule I to a Schedule III controlled substance under the Controlled Substances Act. The DOJ’s notice follows the recommendation of the Department of Health and Human Services (HHS) to reclassify marijuana. The NPRM is silent on what impact the reclassification of marijuana as a Schedule III drug will have on federally mandated drug testing for transportation workers, although U.S. Transportation Secretary, Pete Buttigieg, suggested in testimony before Congress the Department of Transportation would continue to require marijuana testing. If the DOJ eventually reclassifies marijuana to a Schedule III drug, the DOT will need to provide guidance about the impact the reclassification may have on motor carriers, if any.
