Ohio Revised Code Title XXXVII. Health Safety Morals § 3794.04

Because medical studies have conclusively shown that exposure to secondhand smoke from tobacco causes illness and disease, including lung cancer, heart disease, and respiratory illness, smoking in the workplace is a statewide concern and, therefore, it is in the best interests of public health that smoking of tobacco products be prohibited in public places and places of employment and that there be a uniform statewide minimum standard to protect workers and the public from the health hazards associated with exposure to secondhand smoke from tobacco.

The provisions of this chapter shall be liberally construed so as to further its purposes of protecting public health and the health of employees and shall prevail over any less restrictive state or local laws or regulations. Nothing in this chapter shall be construed to permit smoking where it is otherwise restricted by other laws or regulations.
