Is Ketamine legal in United States?

Confirmed against a primary sourceVerified August 31, 2026
Legal status
Schedule III controlled substance under federal law
Consequences if caught
Federal: Schedule III. Ketamine, its salts, isomers and salts of isomers are listed at 21 CFR 1308.13(c) — DEA code 7285. Placed into Schedule III by the DEA final rule at 64 FR 37673, published 13 July 1999 and effective 12 August 1999, corrected at 64 FR 39560 on 22 July 1999. Schedule III substances carry a lower penalty tier than Schedule I or II, but unauthorised distribution and possession remain federal offences.
If prescribed or medical
Available on prescription as an anaesthetic, and as esketamine under a restricted REMS programme. Schedule III prescriptions are refillable within federal limits.
Documentation
Federal scheduling is uniform across the United States. STATE LAW IS NOT, and the federal schedule is not the whole answer for any substance: states set their own offences, thresholds and penalties, and these differ substantially. This states the federal position only.
