BURNEYVILLE, Okla. (KTEN) — The Oklahoma Bureau of Narcotics said it seized more than 45,000 marijuana plants and 700 pounds of processed cannabis during a raid in Burneyville on Tuesday.

OBN spokesperson Mark Woodward said the operators of Harvesting Valley LLC on Baston Road have been cultivating and trafficking "large quantities" of marijuana to the black market.

"OBN agents have conducted undercover purchases of marijuana from the operators of this grow facility," Woodward said in a written statement. "These defendants have ties to the targets of a marijuana trafficking investigation OBN conducted in 2022 that shut down Big Buddha farm in Wilson, Oklahoma."

One person was arrested in the raid at the Harvesting Valley facility, and OBN said additional arrests are expected.

Woodward said agents also found unsanitary living conditions and fire hazards that would jeopardize the health and safety of workers at the facility.

OBN seized hundreds of pounds of processed marijuana from a farm near Burneyville on October 10, 2023.

Cannabis farming has surged across Oklahoma since medical marijuana was legalized in the state, but law enforcement agencies say that has led to a rise in illegal activities.
