Mecklenburg County commissioners are proposing to ban smoking outside of government buildings and in county parks. The ordinance, which commissioners are planning to discuss tonight, would also include bus stops. Under the ordinance, e-cigarettes would also be prohibited. Right now smoking is banned inside county buildings. State lawmakers outlawed smoking inside of state buildings and bars and restaurants in 2009. A public hearing on the proposed county ban is scheduled for this evening during the meeting of county commissioners at the government center in uptown Charlotte.
