Schedules of Controlled Substances: Temporary Placement of MGM-15 and MGM-16 in Schedule I
Published . Updated .
The Drug Enforcement Administration (DEA) is issuing this notice of intent to publish a temporary order to schedule two 7- hydroxymitragynine-related substances (MGM-15 and MGM-16), including their isomers, esters, ethers, salts, and salts of isomers, esters, and ethers, whenever the existence of such isomers, esters, ethers, and salts is possible, in schedule I of the Controlled Substances Act (CSA). On August 26, 2026, DEA published a temporary order placing mitragynine pseudoindoxyl, MGM-15, and MGM-16 in schedule I of the CSA. Today, DEA is providing notice of its intent to publish a new temporary order for MGM-15 and MGM-16 that will maintain the temporary placement of these substances in schedule I of the CSA without change. Separately in this Federal Register, DEA is publishing a notice of intent relating to mitragynine pseudoindoxyl, in response to a letter sent by the Department of Health and Human Services (HHS) dated October 6, 2026. HHS's letter related only to mitragynine pseudoindoxyl. Therefore, DEA is publishing this notice of intent only for the technical and procedural purpose of distinguishing MGM-15 and MGM-16 from mitragynine pseudoindoxyl. When issued, the temporary scheduling order addressing MGM-15 and MGM-16 will continue to 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 these two 7-hydroxymitragynine-related substances. The August 26, 2026 temporary order placing these substances in schedule I of the CSA remains in effect until either it expires or the new temporary order is published and the previous order is withdrawn, whichever occurs first.
