On 8 October 2020 Attorney General Xavier Becerra announced that California’s Campaign Against Marijuana Planting (CAMP) had eradicated more than 1.1 million illegally grown cannabis plants during the 2020 season, in the nation’s largest illegal-grow eradication program.[1][2] Three regional teams raided 455 grow sites across 29 counties over thirteen weeks, arresting 140 people and seizing 174 weapons, despite disruption from COVID-19 and wildfires.[1][2]

The season’s largest single haul was 293,000 plants in Riverside County in the south, and officers also destroyed 20.5 tons (about 18.6 tonnes) of processed marijuana.[2] The campaign combined the state justice department with the U.S. Forest Service, the Drug Enforcement Administration, the California National Guard, wildlife officers and local agencies.[1] Becerra called 2020 the toughest season in the program’s almost forty-year history, and said illegal grows devastate public lands with banned pesticides such as carbofuran while diverting streams for irrigation.[1][2]
