An anonymous reader quotes a report from USA Today: New York state is banning electronic cigarettes indoors everywhere that traditional tobacco cigarettes are prohibited, such as restaurants, bars and other workplaces. The ban goes into effect in 30 days, after Gov. Andrew Cuomo signed the Clean Indoor Air Act on Monday. About 70% of the state's cities already ban e-cigarettes, so the statewide policy captures the rest, according to the American Lung Association. Cuomo signed legislation in July that banned e-cigarettes in public and private schools. The industry, which the Centers for Disease Control and Prevention estimates at $2.5 billion per year, contends that e-cigarettes are safer than traditional tobacco products. Smokers say inhaling the nicotine through a vapor produced by the devices helps them quit traditional cigarettes. But the New York State Health Department warned that vaping carries its own risks because the aerosol emissions can include formaldehyde, cadmium found in batteries, benzene found in gasoline and the industrial solvent toluene.
