DEA Bans Mind-Bending 3-MeO-PCP in Schedule I Crackdown
Published Date: 3/23/2026
Rule
Summary
Starting April 22, 2026, the DEA is putting 3-methoxyphencyclidine (3-MeO-PCP) into Schedule I, meaning it’s now officially a highly controlled substance with strict rules. This affects anyone who makes, sells, studies, or even possesses 3-MeO-PCP, who will face serious legal consequences. This move helps the U.S. follow international drug laws and keeps communities safer.
Analyzed Economic Effects
5 provisions identified: 1 benefits, 4 costs, 0 mixed.
3‑MeO‑PCP Placed Into Schedule I
Starting April 22, 2026, the Drug Enforcement Administration places 3-methoxyphencyclidine (3-MeO-PCP) in Schedule I of the Controlled Substances Act. That means possession, manufacture, distribution, importation, exportation, or other handling of 3-MeO-PCP is subject to the strict criminal, civil, and administrative penalties that apply to Schedule I substances.
DEA Registration Required to Handle 3‑MeO‑PCP
If you handle 3-MeO-PCP (manufacture, distribute, research with, import, export, or possess), you must register with DEA under 21 U.S.C. 822, 823, 957, and 958 and follow 21 CFR parts 1301 and 1312. Any person who currently handles 3-MeO-PCP and is not registered must submit an application and may not continue to handle it unless DEA approves the registration before the effective date.
Strict Compliance Rules for Registrants
DEA registrants handling 3-MeO-PCP must follow Schedule I controls including security requirements, labeling and packaging rules, quotas for manufacture, and recordkeeping and reporting. Registrants must take an initial inventory on the date they first handle controlled substances and thereafter inventory all controlled substances (including 3-MeO-PCP) every two years, and must comply with disposal rules and order form, import/export, and quota requirements.
Research Allowed but Requires Schedule I Registration
The final rule states that placing 3-MeO-PCP in Schedule I does not preclude research, but researchers must comply with DEA's Schedule I registration processes and requirements to conduct research legally. Those who wish to study 3-MeO-PCP must follow the DEA registration process for Schedule I substances before engaging in research.
DEA Says Limited Small‑Entity Economic Impact
DEA certifies under the Regulatory Flexibility Act that this final rule will not have a significant economic impact on a substantial number of small entities. The agency notes there appear to be no legitimate marketed sources for 3-MeO-PCP in the U.S., though legitimate suppliers sell it for scientific research, and there is no evidence of significant diversion from legitimate suppliers.

2026-16413, Schedules of Controlled Substances: Temporary Placement of O-Desmethyltramadol in Schedule I
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.

If finalized, this action would impose the regulatory controls and administrative, civil, and criminal sanctions applicable to schedule V 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 suvorexant, lemborexant, and daridorexant.
2026-15624, Amendment to 3,4-MDP-2-P Methyl Glycidic Acid, a List I Chemical
The Drug Enforcement Administration is proposing to modify the listing of the list I chemical 3,4-MDP-2-P methyl glycidic acid (also known as PMK glycidic acid) to include esters of 3,4-MDP-2-P methyl glycidic acid, not listed elsewhere in the Controlled Substances Act (CSA), as list I chemicals under the CSA. The current listing of 3,4- MDP-2-P methyl glycidic acid includes its salts, optical and geometric isomers, and salts of isomers. DEA proposes the new listing to read as follows: 3,4-MDP-2-P methyl glycidic acid (PMK glycidic acid) and its esters, not listed elsewhere in the CSA, its optical and geometric isomers, its salts, salts of its optical and geometric isomers, salts of its esters, not listed elsewhere in the CSA, and any combination thereof, whenever the existence of such is possible.
