In July 2023, the State Medical Board of Ohio (SMBO) approved the inclusion of irritable bowel syndrome (IBS) as a qualifying condition for the Ohio Medical Marijuana Control Program (OMMCP). This decision was effective immediately and brought the total number of qualifying conditions in the OMMCP to 26.

IBS is a chronic condition that affects the stomach and can cause symptoms such as cramping, abdominal pain, bloating, gas, diarrhea, and constipation. It is estimated to affect between 25 and 45 million people in the United States.

The approval of IBS as a qualifying condition for medical marijuana use in Ohio is expected to expand patient access to medical marijuana and provide relief for many Ohio patients suffering from this condition. However, the SMBO also rejected the petitions for autism spectrum disorder and obsessive-compulsive disorder (OCD) to be included as qualifying conditions.
