March 2026 Newsletter for

Ohio's CTR Physicians

This newsletter is distributed to physicians with an active Certificate to Recommend Medical Marijuana (CTR) and provides important updates for the Ohio Medical Marijuana Control Program (OMMCP). 

The State Medical Board of Ohio has approved 2 new certificate to recommend medical marijuana (CTR) applications since the February board meeting. As of March 11, 2026, the total number of active certified physicians is 513.

CTR Renewal

As a reminder, your Certificate to Recommend is an endorsement that attaches to your current license. It will remain active when you renew your license. You are required to complete 2 hours of CME each year and attest to completion during the online license renewal process. If you have questions about your CTR, email license@med.ohio.gov.

Standard of Care

All physicians with an active CTR must follow the full list of requirements in Ohio Administrative Code 4731-32-03 Standard of Care.

Ohio Division of Cannabis Control Updates

Patient Days’ Supply Increase & Updated OARRS Naming Convention 

The Division of Cannabis Control (DCC or Division) is updating the days’ supply limitations for medical cannabis patients and caregivers, pursuant to Ohio Administrative Code (OAC) 1301:18-8-09. 

Beginning March 24, 2026, medical cannabis patients and their caregivers may purchase up to 2.5 ounces of plant material and 15,000 milligrams of THC for non-plant-material products per day.  

• These amounts increase patient purchase limits, matching those available under statute to non-medical consumers. However, unlike non-medical consumers, medical marijuana patients (not caregivers) may purchase up to four days’ during a single day transaction. This will assist patients with qualifying conditions that make it difficult to get to a dispensary, since they won’t need to make as many trips.    
• Physicians may make additional notes on a patient’s recommendation in the “Instructions” field regarding the types or amounts of products the patient or the patient’s caregiver may purchase. Dispensaries are required to adhere to any such instructions, which are viewable on the patient’s recommendation within the Registry. 
• Each dispensary is responsible for ensuring that all patient transactions are appropriately reported to the Prescription Monitoring Program (i.e., OARRS).  
• While the details of each product purchased must be reported to OARRS, for these purposes only, every product will now be calculated as one day’s supply.  

Additional information, including frequently asked questions, can be found in the updated Medical Cannabis Daily Limits & 90-Day Supply Guidance. 

New Product Types, Potency Limitations, and OARRS Naming Convention 

Also effective March 24, 2026, the Division is updating the naming conventions for all products registered in Metrc beginning March 24. This includes products that were previously available under the medical cannabis program (and continue to be), as well as new product types required by Ohio law. You can review the updated naming conventions here. 

The Division created a spreadsheet to share with physicians which shows the associated package limitations for each of these new product categories, pursuant to OAC 1301:18-4-06. You can find that here.

The Ohio Medical Marijuana Control Program Toll-Free Helpline responds to inquiries from patients, caregivers, and health professionals regarding adverse reactions to medical marijuana, and provides information about available services and additional assistance as needed.
