The federal rescheduling of state-licensed medical marijuana to Schedule III is the most significant change to federal marijuana policy in U.S. history. The information below is intended to give Oklahoma medical marijuana licensees a clear, plain-English picture of what changed, what is required, and what your business should be doing now — sourced directly from the Final Order, the Final Rule, and the relevant federal regulations rather than from secondhand reporting.
At a Glance
- Federal deadline: June 26, 2026. OMMA-licensed businesses that want to keep operating lawfully under the new federal framework must register with the DEA within 60 days of the April 28, 2026 Federal Register publication.
- Registration type follows your OMMA license. Processors and growers register as manufacturers; OMMA transport licensees register as distributors; dispensaries register as dispensers (using the new Form 224-MMP through the DEA’s dedicated medical marijuana portal).
- Only the dispensary portal is live. Manufacturer and distributor portals have not yet rolled out, and we recommend preparing — but not yet filing — those applications until program-specific guidance is published.
- A closed-loop system is forming. DEA registrants will only be permitted to do business with other DEA registrants, so registration is functionally required for any operator that intends to remain in the supply chain.
- Section 280E no longer applies. Medical marijuana businesses can begin taking normal business deductions immediately, and protective IRS refund claims for prior tax years should be considered before statute-of-limitations deadlines run.
- Labeling, security, and reporting requirements largely track state law, with one new federal warning label addition required under 21 U.S.C. § 825(c).

We have received numerous client inquiries about the DEA rescheduling of medical marijuana relevant to state-licensed businesses. Rather than rush to publish, we wanted to take the necessary time to review the actual letter of the law and provide information you can trust to be accurate (and not unverified AI output). Sources for the information below include the Final Order issued by the Department of Justice on April 23, 2026, the corresponding Final Rule published to the Federal Register on April 28, 2026, 21 C.F.R. § 1301.13, the official U.S. Department of Justice, Drug Enforcement Administration website, and other cited sources. This is one of the most significant changes to federal marijuana policy in U.S. history. It is certainly not the time to take shortcuts, by you or the professionals you rely on. With that said, let’s get into it…
Types of Registrations
One of the first challenges to submitting a registration application with the DEA is determining which type of registration you need. Similar to how the business license types issued by OMMA do not directly correspond with the registrations issued by the OBNDD, the same is true for DEA registration types. The Final Rule requires the DEA to “establish an expedited review process for entities holding state medical marijuana licenses who seek registration as a marijuana manufacturer, distributor, or dispenser.” Based on the definitions found in 21 C.F.R. § 1301.13, your registration types will be as follows:
- OMMA Licensed Processors and Growers = Manufacturer Registration
- A “registered manufacturer… may cultivate, produce, process, package, label, and transfer marijuana and products containing marijuana to registered distributors or other registered manufacturers, subject to the limitations of its state license.”
- OMMA Transport Licenses = Distributor Registration*
- A “registered distributor… may receive marijuana and products containing marijuana from registered manufacturers and transfer marijuana and products containing marijuana to registered dispensers or other registered distributors, subject to the limitations of its state license.”
- OMMA Licensed Dispensaries = Dispenser Registration
- A registered dispenser may dispense marijuana and products containing marijuana to individuals authorized by state law to possess marijuana and products containing marijuana for medical purposes, subject to the limitations of its state license.
When to File By
As you have likely already heard, you need to register your state licensed medical marijuana business within 60 days…but within 60 days of what date? The 60-day window is based on when the changes to the statute were published with the Federal Register, which was on April 28, 2026. This means your registration deadline is June 26, 2026.
DEA Registration Applications and Costs
We can anticipate further guidance from the DEA as the new state medical marijuana registrations integrate into the existing DEA registration framework. For now, here is what we know about registration applications and costs:
- Processors and Growers:
- Per the Final Rule issued by the DOJ, the cost for a state licensed medical marijuana manufacturer is $3,699 annually. However, as of the date of this publication, the DEA has not rolled out a specific registration portal or program-specific form for state medical marijuana manufacturer registrants as has been done for dispensaries, so this could change. It may be wise to prepare for but not yet file for manufacturer registrations with the DEA due to anticipated rollouts to come.
- Transporters*:
- ◦ The DOJ’s Final Rule states the fee for distributor registrations to be $1,850 annually. However, as explained in relation to manufacturer registrations, this could change upon a program-specific registration rollout, and we would caution against registering before that time. *Note, it remains unclear if all business licensees would need to register as a distributor in addition to a manufacturer or dispenser registration in order to transport medical marijuana product under the transport license that OMMA issues along with each business license. Many other states have a specific “distributor” license that Oklahoma does not have. In Oklahoma, stand-alone transport licenses issued by OMMA would fall into this category.
- Dispensaries:
- The DEA’s traditional “dispenser” registration fee is $888 for a three-year period, which is what the Final Rule indicated the cost would be. However, the new medical marijuana dispensary registration portal (and newly created Form 224-MMP) currently reflects a fee of $794, which appears to be a program-specific (or perhaps a prorated) amount. Note, it is also unclear if this new program-specific registration will be for a three-year period.
NEW Registration Portal for State Medical Marijuana Dispensaries
The DEA recently launched a new registration portal specifically for state licensed medical marijuana dispensaries. On the surface, the application seems fairly simple. However, the required disclosures make the process far more complicated. For example, you are required to disclose any past agency actions (by OMMA or OBNDD) filed against the business or its owners, changes in ownership over the past 12 months, and any past disciplinary actions against “each individual you anticipate having access to controlled substances” meaning all employees and their legal history will need to be disclosed. You will also have to disclose “each supplier” you intend to procure medical marijuana products from. This relates to the closed-loop system DEA registration is creating for state medical marijuana licensees, which is discussed below. The DEA website has the instructions for registration available to preview before beginning your application. We strongly suggest you gather all the information outlined in the instructions immediately and before you begin the application process.
Tax Changes Now That 280E No Longer Applies
One of the major bonuses referenced in the DOJ Order is that IRS Section 280E — which disallowed businesses “trafficking in controlled substances… in a schedule I or II” normal business tax deductions — will no longer apply to medical marijuana licensed businesses since medical marijuana is now in Schedule III. The DOJ Order explicitly says state licensees “will no longer be subject to the deduction disallowance imposed by Section 280E” and encourages the Treasury Secretary “to consider providing retrospective relief” for past taxable years.
This change will allow you to start taking normal business tax deductions immediately. And there is potential to save more if the Treasury Secretary decides to provide retrospective relief. Medical marijuana businesses may want to file protective refund claims with the IRS for prior tax years where 280E disallowances were applied. Refund claims are generally limited to three years from the date of filing (or two years from payment). If you would like to receive information on filing protective refund, please provide your information in the form HERE. There is no guarantee retroactive application of the change will be applied, but you can secure your position if it does.
Clarifying Confusion and Answers to Specific Questions
Since April 23, our office has received an onslaught of inquiries from clients and colleagues seeking to gain clarity amid the chaos. Below we address the most common questions and misconceptions we have seen thus far and do our best to provide some answers.
Q: Is registering my state medical marijuana business license with the DEA necessary? (Thank you to this OMMA email for causing confusion).
A: Technically, no… but if you want to stay in business, yes. Here’s why…
As mentioned in the section on registering your dispensary, the DEA registration is going to create what we are referring to as a “closed-loop system” meaning only DEA registrants may do business with other DEA registrants. If you revisit the definitions provided under the “Types of Registrations” section above, you will see that manufacturers may only transfer medical marijuana “to registered distributors or other registered manufacturers” and distributors may only transfer medical marijuana “to registered dispensers or other registered distributors.” Meaning, if you want to do business with any business that DOES register with the DEA, you will need to also.
*It is also important to note that as it reads now, manufacturers can only transfer to “distributors” (i.e. transporters), who can then transfer to “dispensers” (i.e. dispensaries) which may require you register your business as a “distributor” if you do not use a separate transportation company to transport product.
Q: Are labeling requirements changing?
A: Yes, but only minimally.
The Final Rule specifically states that state medical marijuana businesses that register with the DEA will be “exempt from the labeling, packaging, and sealing requirements under part 1302 of this chapter, and other provisions of these rules so long as they label, package, and seal marijuana and products containing marijuana in conformity with state law and so long as the label includes the warning required by 21 U.S.C. 825(c), where applicable.”
The warning label requirements you do need to add must “contain a clear, concise warning that it is a crime to transfer the drug to any person other than the patient.”
Q: Can you purchase out of state medical marijuana and/or have it shipped to you?
A: No. At least not yet.
Opening interstate cannabis commerce will require an act of Congress — whether through broad cannabis reform legislation or a narrowly tailored amendment to the Controlled Substances Act. The STATES Act, the Cannabis Administration and Opportunity Act (CAOA), and other pending bills represent the most viable legislative pathways to achieving this. That said, rescheduling may lower political barriers and generate renewed congressional momentum in the near term.
Q: Do I have new reporting requirements?
A: No, but you need to make sure all reporting is compliant with state laws and available for inspection by the DEA.
The DEA is going to accept your state reporting “to the maximum extent permissible” to comply with Federal security requirements. We anticipate additional guidance will be issued on this (and all) topics, but one thing the Final Rule makes clear is that what is reported to the state will be disclosed to the Feds as well. Now is the time to button up compliance.
Q: Does all medical marijuana from my grow have to be sold to the DEA first now?
A: Yes. In order to comply with the United Nations Single Convention on Narcotic Drugs, all marijuana in the country must be purchased and be wholly monopolized by the DEA.
However, this is a formality. In practice, the DEA purchases all marijuana crops at a nominal rate and then sells it back to the business it purchased it from at the same price along with an administrative fee. Additionally, the DEA must be able to access storage facilities where marijuana is held at all times and can inspect at any time on demand. Again, we can anticipate more guidance on this topic soon.
Q: Do I need to update any of my security?
A: No. Not as long as you are compliant with state laws.
Although the dispensary application does ask for specific security measures to be disclosed, the Final Rule indicates that so long as you are compliant with state requirements, you will satisfy DEA requirements. That said, it is definitely a good time to make sure all security measures are up to par.
