Do you expect medical marijuana prices in your area to decrease due to new tax deductions?

The federal government reclassified medical marijuana from a Schedule I to a Schedule III drug, a change that took effect April 22, 2026. This order applies retroactively to January 1, 2026, and alters the tax landscape for marijuana businesses.

Why it matters

By moving to Schedule III, businesses gained the ability to deduct ordinary operating expenses, shifting their tax burden from gross profit to net income. This change aims to align tax treatment for these entities with standard business practices across the United States.

Federal rules now permit deductions for expenses, replacing a previous structure that taxed gross profit. While the regulation applies to businesses, Arkansas saw sales drop 2.6% to $140.3 million during the first half of 2026 despite active patient counts rising to 119,013 by September.

The players

Drug Enforcement Administration

The federal agency responsible for enforcing the controlled substances laws and managing the rescheduling requirements for businesses.

U.S. Treasury

The federal department overseeing the potential amendment of tax filings for marijuana businesses following the rescheduling.

The details

Previously, federal tax codes prevented medical marijuana dispensaries from deducting standard business expenses, forcing them to pay taxes on their total gross revenue. Now, these entities can deduct operational costs to arrive at a net income figure for tax purposes, though they face stricter DEA regulatory compliance requirements. These new overhead costs for compliance may offset the savings generated by the tax change.

January 1, 2026: The federal rescheduling order became retroactively effective.
April 22, 2026: The federal rescheduling order officially took effect.
First half of 2026: Arkansas medical marijuana sales declined by 2.6%.
September 2026: The count of active medical marijuana patients in Arkansas reached 119,013.

Money Landscape

This policy update marks a significant shift in the federal oversight of the medical marijuana industry. It represents the first major change in tax treatment for these businesses under the Controlled Substances Act.

While these tax changes apply directly to business operations, they may indirectly influence the price and availability of medical marijuana for registered patients. Households should speak with a tax professional regarding how industry-wide regulatory shifts could impact local market costs.

The takeaway

The move to Schedule III fundamentally changes how dispensaries handle their taxes by allowing standard business expense deductions. Monitor local pricing and availability, as the increased compliance requirements for businesses could affect your out-of-pocket costs at the dispensary.
