Schedules of Controlled Substances: Placement of Diphenidine in Schedule I

The Drug Enforcement Administration proposes placing diphenidine (1-(1,2-diphenylethyl)piperidine), including its salts, isomers, and salts of isomers whenever the existence of such salts, isomers, and salts of isomers is possible, in schedule I of the Controlled Substances Act. This action is being taken, in part, to enable the United States to meet its obligations under the 1971 Convention on Psychotropic Substances. If finalized, this action would impose the regulatory controls and administrative, civil, and criminal sanctions applicable to schedule I controlled substances on persons who handle (manufacture, distribute, reverse distribute, import, export, engage in research, conduct instructional activities or chemical analysis with, or possess) or propose to handle diphenidine.

Schedules of Controlled Substances: Temporary Placement of 2-Fluorodeschloroketamine in Schedule I

The Drug Enforcement Administration (DEA) issues this temporary order to schedule 2-(2-fluorophenyl)-2- (methylamino)cyclohexan-1-one (commonly known as 2- fluorodeschloroketamine or 2-FDCK), including its salts, isomers, and salts of isomers whenever the existence of such salts, isomers, and salts of isomers is possible within the specific chemical designation, in schedule I of the Controlled Substances Act. DEA bases this action on a finding that placing 2-fluorodeschloroketamine in schedule I is necessary to avoid an imminent hazard to public safety. This order imposes the regulatory controls and administrative, civil, and criminal sanctions applicable to schedule I controlled substances on persons who handle (manufacture, distribute, reverse distribute, import, export, engage in research, conduct instructional activities or chemical analysis, or possess), or propose to handle this substance.

Schedules of Controlled Substances: Rescheduling of Food and Drug Administration Approved Products Containing Marijuana From Schedule I to Schedule III; Corresponding Change to Permit Requirements

With the issuance of this final rule, which constitutes a final order, the Acting Attorney General of the U.S. Department of Justice places drug products containing marijuana that have been approved by the Food and Drug Administration (FDA) in schedule III of the Controlled Substances Act ("CSA"). This action is required to satisfy the responsibility of the Administrator under the CSA to place a drug in the schedule he deems most appropriate to carry out United States obligations under the Single Convention on Narcotic Drugs, 1961. In general, this final rule applies to marijuana as defined in the CSA, marijuana extracts, and delta-9-tetrahydrocannabinol and other compounds derived from the marijuana plant (other than the mature stalks and seeds) that falls outside the definition of hemp, to the extent that any of these are included in an FDA-approved drug product or are subject to a state-issued license to manufacture, distribute, and/or dispense marijuana or products containing marijuana for medical purposes ("state medical marijuana license"). Also consistent therewith, this final rule adds such drugs to the list of substances that may only be imported or exported pursuant to a permit. This final rule also establishes an expedited registration process under 21 CFR part 1301 for entities holding state medical marijuana licenses, enabling such entities to engage in the manufacture, distribution, and/or dispensing of marijuana for medical purposes under federal law consistent with the requirements of the Single Convention.

Procedures for Transportation Workplace Drug and Alcohol Testing Programs: Addition of Fentanyl to the Department of Transportation's Drug-Testing Panel; Harmonization With Certain Items in the HHS Mandatory Guidelines for Urine and Oral Fluid; and Technical Amendments

The U.S. Department of Transportation (Department or DOT) proposes to amend its drug-testing program regulation, 49 CFR part 40 (part 40), to add fentanyl (a synthetic opioid) and norfentanyl (a metabolite of fentanyl) to its drug testing panels. The proposed rulemaking would harmonize part 40 with the U.S. Department of Health and Human Services (HHS) Mandatory Guidelines for Federal Workplace Drug Testing Programs (Mandatory Guidelines), which DOT must follow for the minimum list of drugs for which DOT requires testing, and the comprehensive standards for laboratory drug testing per the Omnibus Employee Testing Act of 1991. Adding fentanyl and norfentanyl is also in the interest of transportation safety, given compelling information regarding the number of overdose deaths in the United States involving fentanyl. The Department also proposes to amend certain provisions of part 40 to harmonize, as appropriate, with the current HHS Mandatory Guidelines using urine (UrMG) and oral fluid (OFMG). This NPRM also proposes to clarify certain existing part 40 drug testing program provisions and to make technical amendments.
