The Ohio Medical Marijuana Program is banning vitamin E acetate in the manufacturing of vaporization products. 

The ban comes directly on the heels of the recent findings from the CDC that found that 29 patients with vaping-related illnesses all had the acetate in their lung fluid. 

This is the first time the CDC has detected a potentially concerning chemical connected to vaping-related injuries. 

"The Ohio Department of Commerce has issued guidance on the prohibition of vitamin E acetate in Medical Marijuana Control Program products used for vaporization and will work with the licensed testing labs to ensure that these products are tested for the presence of this ingredient," said Sheryl Maxfield, Director of the Ohio Department of Commerce.

This is proactive; as of now, no current manufacturers use the ingredient.
