Part of the legalization argument is that regulating and taxing marijuana could give California enforcement agencies the funds they need to eradicate illegal farms. But Gabriel thinks it will take years before enforcement can put a dent in the illegal grows that he estimates pop up by the hundreds every year. He points to Humboldt County, about five hours northwest of Calaveras, where authorities are combing through 2,300 applications for growers who want to start selling in California’s recreational market. But there are also an estimated 12,700 illegal farms in the county.
