The Ohio State Highway Patrol seized 250 pounds of marijuana during a traffic stop in Madison County.
Troopers stopped a Penske truck with Indiana registration for a speed violation on Interstate 70 at 12:19 p.m. Monday.
OSHP said criminal indicators were observed and a patrol drug-sniffing K-9 alerted to the vehicle. A probable cause search revealed the marijuana, valued at $1.2 million.
The driver, 23-year-old Benjamin Malugani of California, was taken to the Tri-County Jail and charged with possession of marijuana.
If convicted, he faces up to eight years in prison and up to a $15,000 fine.
