Schedule III and rescheduling

Rescheduling moves a substance from one schedule of the Controlled Substances Act to another. In April 2026, marijuana covered by a qualifying state medical license moved from Schedule I to Schedule III, while adult-use marijuana remains in Schedule I.

How federal drug scheduling works

The Controlled Substances Act sorts drugs into five schedules. Schedule I is the most restrictive and covers substances considered to have a high potential for abuse and no accepted medical use. Schedules II through V cover substances with accepted medical uses and decreasing potential for abuse.

For decades, all marijuana sat in Schedule I. That classification drove the cannabis industry's biggest financial problems, including Section 280E and banks' reluctance to serve cannabis businesses.

What changed in April 2026

In April 2026, marijuana covered by a qualifying state medical license moved to Schedule III. Adult-use marijuana remains in Schedule I. The practical effects include:

  • Taxes: Section 280E no longer applies to qualifying medical activity, so those operators may deduct ordinary business expenses.
  • Recordkeeping: Operators with both medical and adult-use activity need records that clearly separate the two.
  • Legal status: Rescheduling does not make marijuana federally legal. Medical marijuana remains a controlled substance, and adult-use marijuana remains in Schedule I.

What it means for banking

Financial institutions still apply due diligence and ongoing monitoring to cannabis accounts under the Bank Secrecy Act. Requirements can vary by institution, so operators should keep licensing, ownership and financial records current and ask their bank how its program applies to medical and adult-use activity.

How Safe Harbor helps
