The publisher's summary

The Drug Enforcement Administration issues this temporary order to schedule O-desmethyltramadol (other names: O-DSMT; desmetramadol; 3-[(1R,2R)-2-[(dimethylamino)methyl]-1- hydroxycyclohexyl]phenol), including its isomers, esters, ethers, salts, and salts of isomers, esters and ethers, in schedule I of the Controlled Substances Act. DEA bases this action on a finding that placing O-DSMT 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 with, or possess) or propose to handle O-DSMT.
