Challenging 280E: Why 'Within the Meaning' Matters

The language of IRC Section 280E is deceptively simple on its surface, but a close reading reveals interpretive space that cannabis operators should be leveraging. The statute denies deductions to businesses trafficking in controlled substances "within the meaning of" the Controlled Substances Act. That phrase - "within the meaning of" - is doing a lot of heavy lifting.

The HHS Recommendation

In August 2023, HHS formally recommended that cannabis be moved from Schedule I to Schedule III of the Controlled Substances Act. This recommendation was based on a thorough scientific and medical review concluding that cannabis has accepted medical use and a lower potential for abuse than Schedule I classification implies.

If HHS - the agency with statutory authority over scientific and medical scheduling determinations - has concluded that cannabis does not meet the criteria for Schedule I, then cannabis is arguably no longer a Schedule I substance "within the meaning of" the CSA's definitional framework. The DEA's failure to act on that recommendation does not change the underlying scientific determination.

DOJ and OLC Support

In April 2024, the Department of Justice's Office of Legal Counsel issued an opinion supporting a more flexible standard for evaluating scheduling criteria. The OLC found that the DEA's historical approach to defining "accepted medical use" was unduly rigid and that a broader, evidence-based standard was appropriate. This opinion directly supports the argument that cannabis's scheduling status should be evaluated based on current evidence rather than formal classification alone.

The IRS Position

The IRS has consistently insisted that 280E remains in full effect until cannabis is formally reclassified. But there is a meaningful gap between IRS guidance and IRS enforcement. While the IRS has issued statements and internal memoranda asserting 280E's continued applicability, the agency has not disputed the strategy in Tax Court. This gap is significant.

Section 471(c) as a Practical Tool

For cannabis businesses with gross receipts under $29 million, IRC Section 471(c) provides a practical mechanism for capturing additional deductions through inventory accounting methods. This section allows qualifying small businesses to use alternative accounting methods that effectively move costs into cost of goods sold - the one category of deduction that 280E does not disallow.

Section 471(c) is not a theoretical argument - it is a practical, codified tool that cannabis businesses can and should be using right now.

The Path Forward

Cannabis operators have two primary options: amend past returns to claim deductions that were foregone under a conservative reading of 280E, or stop complying with 280E going forward based on the legal arguments supporting reclassification. Both approaches carry risk, but both are legally defensible when properly documented and disclosed.
