"Operation Heat" nets 3.5 pounds of marijuana brownies and a significant amount of heroin in two separate cases.
Athens County Sheriff Patrick Kelly says 54-year-old John Wagoner is charged with aggravated trafficking in drugs.
His arrest led to two others.
32-year-old Derek Mays, who is charged with possession of a bulk amount of heroin plus tampering with evidence and 44-year-old Doug Coen, who is charged with possession of heroin.
That was Thursday.
Friday deputies stopped two juveniles - 15- and 16-years of age - who they say had ten bags of marijuana brownies.
Their charges are pending based on lab test results.
