Groups against smoking are urging the St. Louis County Council to make changes to the smoking ban that went into effect last year.
Currently, businesses whose food sales result in 25 percent of gross sales including food, alcoholic and non-alcoholic drinks are eligible for an exemption from the smoking ban. There are 145 businesses that currently allow smoking in the county.
A higher percentage of Missouri's workers are exposed to secondhand cigarette smoke than in any other state.
A 2007 telephone survey funded by the Missouri Foundation for Health looked at the tobacco use, health, and demographics of close to 24,000 indoor Missouri workers. About 12 percent were exposed to secondhand smoke, compared to about 7 percent of workers nationwide.
