State and federal drug enforcement officials say they have pulled more than 5 million marijuana plants from public and private land this year, a record amount.

The state Department of Justice, U.S. Drug Enforcement Administration and other agencies announced Wednesday that they have seized 5.2 million marijuana plants. Most of those were on public land.

John Gaines, chief of California's Bureau of Narcotic Enforcement, says more than half the nation's domestically produced marijuana is grown in California.

State and federal agencies participating in the Campaign Against Marijuana Planting and Operation Green Acres 2 also made 143 arrests and seized 142 weapons.

The marijuana cultivation season generally runs from July through October.
