Federal Cannabis & Hemp Update: Major Changes Ahead
Two significant federal developments are poised to reshape the cannabis and hemp landscape:
A narrowing of the federal definition of “hemp” under Public Law 119-37, effective November 12, 2026; and
Accelerated efforts to reschedule marijuana from Schedule I to Schedule III under the federal Controlled Substances Act (21 U.S.C.).
While neither change legalizes marijuana federally, both carry substantial regulatory and economic implications.
1. Federal Hemp Law Update — Effective November 12, 2026
Congress has enacted major revisions to the federal hemp framework that significantly narrow what qualifies as lawful hemp.
Key Change: Synthetic and Converted Cannabinoids Excluded
Under the updated definition, hemp will no longer include:
Delta-8 THC
Delta-10 THC
THC-O
HHC
THCP
Other synthetic or chemically converted cannabinoids
The law places strict limits on THC and THC-like compounds in consumer hemp products, effectively restricting hemp to non-intoxicating uses.
Congress also authorized the FDA to determine which cannabinoids have effects similar to THC or are marketed as intoxicating, granting regulators broad discretion in enforcement.
Practical Impact
This change is aimed at cannabinoid conversion and chemical manipulation—not traditional hemp cultivation. The regulatory focus is on chemistry, not crops.
Businesses operating in the hemp-derived cannabinoid market should evaluate inventory models, product lines, and supply chains well in advance of the effective date.
2. Cannabis Rescheduling: Schedule I to Schedule III
Separately, federal officials have accelerated efforts to move marijuana from Schedule I to Schedule III under the Controlled Substances Act.
On December 18, 2025, the President signed an Executive Order directing the Attorney General and relevant agencies to expedite the rescheduling process. Formal rescheduling will still require federal rulemaking and administrative action.
While rescheduling would not legalize marijuana federally, it could produce meaningful regulatory changes.
Potential Effects of Schedule III
Tax Treatment
The most immediate impact would involve Internal Revenue Code § 280E.
Section 280E disallows ordinary business deductions for businesses trafficking in Schedule I or II controlled substances. If marijuana is placed in Schedule III, § 280E would no longer apply to marijuana operators under the statute’s plain language.
This would allow standard business deductions for general operational costs.
For state-licensed operators, this change could be economically significant.
Banking
Rescheduling may reduce perceived compliance risk for financial institutions. However, it would not eliminate Bank Secrecy Act obligations or suspicious activity reporting requirements.
Meaningful expansion of traditional banking access likely requires separate federal legislation.
Research
Schedule III status would reduce DEA research barriers. Researchers would still be subject to DEA registration requirements, FDA oversight where applicable, and state-level compliance rules.
Rescheduling would ease—but not eliminate—federal research constraints.
Interstate Commerce
Rescheduling alone would not open interstate commerce.
Because the change would occur through administrative rulemaking—not congressional legalization—federal prohibition would remain in place. Interstate cannabis commerce would likely require additional federal statutory reform.
In practical terms, Oklahoma’s medical marijuana market would continue operating primarily intrastate for the foreseeable future.
Bottom Line
The federal hemp revisions represent a contraction of the intoxicating hemp market beginning November 12, 2026.
The proposed marijuana rescheduling represents regulatory recalibration—not legalization.
Both developments signal continued federal involvement in cannabinoid regulation. Businesses operating in hemp or state-licensed cannabis markets should monitor rulemaking closely and begin strategic planning well in advance of implementation.
Further federal guidance and enforcement priorities will determine the full impact of these changes.
