With their push to end smoking in Atlantic City’s casinos going nowhere fast in either the courts or the state Legislature, casino workers and supporters of smoke-free gambling halls demonstrated late last week outside a hotel where New Jersey’s governor was due to speak. The workers have been pushing for four years to end an exemption in New Jersey’s clean air law that allows smoking inside the nine casinos. They say they or their co-workers are becoming ill with cancer, heart disease and other conditions related to exposure to second-hand smoke. Gov. Phil Murphy has said he will sign a bill to end casino smoking once it reaches his desk.
