Ohio Attorney General Mike DeWine is reminding business owners that they will face serious criminal and civil penalties if caught selling synthetic drugs. 

The warning came after agents with the Bureau of Criminal Investigation (BCI) assisted Belmont County Sheriff’s deputies with serving four search warrants related to the sale of synthetic marijuana and herbal incense. 

Dewine’s office says Wednesday's search warrants were served at the Trading Post in Bridgeport and at the home of its owner, also at the Shadyside Party Center and at Bob's Cheap Smokes in St. Clairsville. 

One person was taken into custody.

Investigators found that those at the businesses were selling the synthetic drugs under names including "Caution," "California Dreams," "Kush Max," and "Mr. Happy."
