COPPEROPOLIS, Calif. (AP) – Marijuana has deeply divided a Northern California county in the Sierra Nevada foothills. Calaveras County Sheriff Rick DiBasilio says he has his hands full cracking down on thousands of illegal farms in a county that has legalized cultivation for medicinal use. Growers illegal and legal have are increasingly open about their operations and starting to encroach on neighborhoods. DiBasilio estimates that there are more than 1,000 illegal farms in addition the hundreds with permits or in the process of obtaining permits in a county about the size of Rhode Island, with a population of 44,000. The influx has caused a backlash among residents and led to the ouster of some county leaders who approved marijuana cultivation.
