Nagasaki University（N.U.）in Japan will no longer accept teachers who smoke. It wants to create a healthier environment for workers and students. The university’s president S. Kono said, “Our job is to look after our staff（职员）. We think we have to discourage them from smoking.” He added, “There will be no smoking anywhere in the university from August 2022.What’s more, staff and students can’t take cigarettes into any areas of the university from next year.”
