{"abstract":"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.","action":"Notice of proposed rulemaking.","agencies":[{"raw_name":"DEPARTMENT OF JUSTICE","name":"Justice Department","id":268,"url":"https://www.federalregister.gov/agencies/justice-department","json_url":"https://www.federalregister.gov/api/v1/agencies/268","parent_id":null,"slug":"justice-department"},{"raw_name":"Drug Enforcement Administration","name":"Drug Enforcement Administration","id":116,"url":"https://www.federalregister.gov/agencies/drug-enforcement-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/116","parent_id":268,"slug":"drug-enforcement-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2026/05/26/2026-10380.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"1308","title":21}],"citation":"91 FR 30519","comment_url":"http://www.regulations.gov/commenton/DEA-2026-0892-0001","comments_close_on":"2026-06-25","correction_of":null,"corrections":[],"dates":"Comments must be submitted electronically or postmarked on or before June 25, 2026.
