The Ohio Attorney General's Office said warrants were served in three counties on Friday as part of a crackdown on the sale of synthetic drugs.
Lawmen served warrants in Clark, Montgomery and Guernsey counties.
An investigation revealed three stores selling synthetic cannabinoids, which is also known as synthetic marijuana or herbal incense, according to the AG's office.
Attorney General Mike DeWine said businesses were warned in November of the risks.
"We gave business owners fair warning that if we found synthetic drugs in their stores that there would be consequences, and now we are following through with that promise," said DeWine.
The Quality Food Market in New Carlisle, Buddy's Drive Thru in Byesville and the Party Time Carryout in Cambridge were among the stores served on Friday.
