LOS ANGELES (AP) The largest illegal marijuana bust in Los Angeles County history which netted 373,000 plants that would ultimately have been worth $1 billion on the street eradicated only a fraction of the illicit grows in the Southern California high desert, authorities said Wednesday.

The problem is wide-ranging in the Antelope Valley north of Los Angeles, officials said, and has grown tremendously during the coronavirus pandemic. Armed cartel members run massive illegal grows, some spanning dozens of greenhouses, that are detrimental to the states legal marijuana market.
