The Mardi Gras Casino is seeking an exemption from Kanawha County’s Clean Air Act to allow indoor smoking in their facilities. The worry is they’ll lose revenue without a smoking option. The Kanawha County Commission said it has not yet received an official proposal. Eyewitness News said, when the proposal is made to the health department there will be a 30 day comment period, then the commission will review it and either accept or reject.
