Business owners can see if a citizen complaint was filed against them for violation of the smoking ban, during the period of Dec. 7, 2006 and Apr. 24, 2007 by visiting Cincinnati.com Smoking Complaints Datacenter. The smoking ban was officially in effect as of Dec. 7, 2006, but not being enforced due to lack of regulations. The Department of Health says that these complaints will not count against businesses once enforcement begins.
