Schedule III Is Here for Medical Cannabis: What the 2026 Federal Rescheduling Order Means for Operators

Federal cannabis policy has finally moved. On April 22, 2026, the Acting Attorney General issued a final order — effective April 28 — placing marijuana in Schedule III of the Controlled Substances Act, but only where it is an FDA-approved drug product or subject to a qualifying state-issued medical marijuana license. Everything else, including state-licensed adult-use cannabis, remains in Schedule I for now.

The order has already survived its first court test. On September 9, 2026, a three-judge panel of the U.S. Court of Appeals for the D.C. Circuit refused to pause the order while legal challenges proceed. Those challenges are still pending on the merits, so the order stands — but operators should understand that litigation could continue for a year or more.

For state-licensed medical operators, the tax implications are immediate and significant. Because Internal Revenue Code Section 280E applies only to Schedule I and II substances, qualifying medical marijuana businesses can now deduct ordinary business expenses — a change that can cut effective federal tax rates dramatically. The final rule also created an expedited federal registration process for entities holding qualifying state medical licenses.

Adult-use operators are in a different position. A separate DEA rulemaking on moving all marijuana to Schedule III went through an eleven-day evidentiary hearing in June and July 2026, and the parties are now awaiting the administrative law judge's recommended decision. Until a final rule issues, adult-use businesses remain subject to 280E and the existing federal-state conflict.

What should operators do now? Medical licensees should confirm their state license qualifies under the order, complete the expedited federal registration, and work with tax counsel on amended positions and going-forward deductions. Adult-use operators should prepare for a possible broader Schedule III rule while continuing to plan under current law. Either way, entity structures, intercompany agreements, and compliance documentation should be reviewed with counsel now — the businesses that prepared early will capture the benefits fastest.
