The DEA Gives 3-CMC Its Own Official Drug-Code Listing
Published Date: 11/6/2026
Rule
Summary
The DEA is officially listing 3-chloromethcathinone (3-CMC) as a Schedule I drug with its own code, making it clear this substance is illegal like its close cousin 4-CMC. This change starts November 6, 2026, and affects anyone handling or selling this drug, tightening control and enforcement. No new costs are expected, just clearer rules to keep things safe and straightforward.
Analyzed Economic Effects
4 provisions identified: 3 benefits, 1 costs, 0 mixed.
3-CMC continues to be a Schedule I controlled substance
The rule states that 3-CMC has been and remains a Schedule I controlled substance (it was controlled as a positional isomer of 4-CMC since December 17, 2025). All regulations and criminal sanctions that apply to Schedule I substances continue to apply to 3-CMC.
3-CMC gets its own Schedule I listing
The DEA added 3-chloromethcathinone (3-CMC; 1-(3-chlorophenyl)-2-(methylamino)propan-1-one) as a separately listed Schedule I substance and assigned it DEA drug code 1241. This specific listing is effective November 6, 2026 and formally clarifies that 3-CMC is controlled under Schedule I.
DEA can set production and manufacturing quotas
By assigning a separate code for 3-CMC, DEA can establish an aggregate production quota and grant individual manufacturing and procurement quotas under that code to DEA-registered manufacturers. The rule notes manufacturers previously received quotas under the 4-CMC code, and the change is effective November 6, 2026.
No new paperwork or reporting requirements
The DEA states this final rule does not create new information collection, recordkeeping, or reporting requirements under the Paperwork Reduction Act and would not impose new recordkeeping or reporting duties on State or local governments, individuals, businesses, or organizations.
