The Navajo Nation is banning tobacco use in many indoor locations on the reservation, including its casinos. President Jonathan Nez signed legislation Saturday after tribal lawmakers approved the bill last month. Nez calls the ban, “a monumental achievement and bold step in the right direction to promote healthy living” among the Navajo people. The new law prohibits the use of cigarettes, chewing tobacco, e-cigarettes and other tobacco products in public buildings and workplaces. The ban wouldn’t apply to the ceremonial use of tobacco in homes unless the homes are being used as a business.
