More charges are pending against David Bowen, owner of The Odyssey Shop and Jessica Staton, an employee at the businesses.
Investigators said those charges could be added when the case goes to the grand jury.
Deputies raided the Odyssey Shop in Teays Valley Wednesday and found synthetic marijuana and several guns. Investigators said one of the guns was stolen.
Investigators also recovered a large amount of cash from Bowen's Barboursville home.
They said both suspects are major players in the synthetic drug trade.
