The University of Louisville may follow the University of Kentucky in broadening a ban on outdoor smoking.UK President Lee Todd said this week that the school could approve a ban by next fall.Committees in U of L’s governing bodies are considering a similar proposal, but no timeline has been set. U of L College of Health Sciences spokesperson Ellen de Graffenreid says before a rule is put in place, the school wants to help students, staff and faculty quit smoking.“Definitely they would want to support people having a healthy workplace environment and understanding that it is difficult to quit smoking, some of those resources would be available and in fact are available through the U of L health plans at this time," she says.Smoking is already prohibited on U of L’s Health Sciences campus. Currently, Campbellsville University is the only college in Kentucky to have a ban on outdoor smoking.
