Print Faced with an invasion of massive, illegal pot farms in California’s high desert, Los Angeles County Supervisors have voted to boost enforcement and reconsider their current ban on commercial marijuana cultivation. The move Tuesday follows months of complaints from residents and authorities who say the large-scale black market farms have upended life in the desert. Authorities say the boom has led to forced labor, violence, water theft and the destruction of fragile desert habitat and wildlife. Longtime residents say they feel less safe, claiming black-market growers act with impunity by carrying weapons, trading gunfire with rivals and threatening those who wander too close to their farms.
