Restrooms are often small and poorly ventilated. People use the restroom because it is a necessary room. They expect it to be clean. When smoking is permitted, not only is the air fouled with dangerous chemicals and carcinogens, but the cigarette and cigar butts are floating in the toilet, cigarette burns are on the toilet seat, ashes are on the floor, and occasionally a fire is started in the trash bin. The smoking damage causes economic damage for businesses.
Parents take children and infants into the public restrooms.
Children are especially susceptible to smoke, and a high number are hospitalized each year from illnesses of the ear, nose, and throat as well as the respiratory system, which are caused by and exacerbated by secondhand smoking. And the fetus is very vulnerable to smoke. The scientists observed that the nonsmoking women had been around smoke in the workplace, etc. Elderly people are very vulnerable to smoke. This simple preventive health measure would hurt no one, no business, no farmer.
