The American Cancer Society (ACS) of Ohio has filed a lawsuit challenging the state's workplace smoking ban. The ban exempts some military veterans' halls and other private clubs -- and the ASC says this is not OK.

The exemption waters down the law and exposes people to secondhand smoke, say ACS spokeswoman Wendy Simpkins.

The smoking ban was approved by 58 percent of voters in November, took effect in December, and will result in fining beginning the first week in May. The law prohibits smoking in most public places, such as restaurants, bars, and office and excludes tobacco shops, designated hotel rooms, and enclosed areas of nursing homes. Halls and clubs can be excluded from the law only if there are no employees.

Jay Carey, spokesman for the state Health Department, says public health officials have the authority to set rules for enforcement. They ultimately decided that VFW halls and other private clubs were exempt if they had only members as employees. For the exemption to apply, such clubs also must be nonprofit and in a freestanding building. No nonmembers or children under age 18 can be present.

The ACS argues that the state rules are confusing and make the law unworkable.

Secondhand smoke rears its ugly head once again -- this time in the form of study results revealing high levels of secondhand smoke in the workplace can double the risk of lung cancer for non-smokers.

Researchers at the University of Illinois at Chicago looked at results from 22 studies conducted in the United States, Canada, Europe, India, Japan, and China. What they found -- and published in the American Journal of Public Health -- is a lung cancer risk 50 percent higher than normal for non-smokers exposed to smoke on the job for more than 30 years. They also found risk increases with level of exposure.

"We believe that our study provides the strongest evidence to date that smoking in the workplace does present a substantial risk to workers -- and particularly to workers who are working in highly exposed areas such as bar workers or restaurant workers," lead researcher Leslie Stayner said.

Previous evidence for increased lung cancer risk caused by secondhand smoke comes from studies of non-smokers married to smokers.

Secondhand smoke -- also known as passive smoke and environmental tobacco smoke -- is smoke from a cigarette, pipe, or cigar as well as smoke exhaled from the lungs of smokers and inhaled by non-smokers. It can cause cancer, respiratory problems, and asthma in non-smokers and is leading to increased efforts by communities to ban or limit smoking in the workplace.

This week in France, bans begin in offices, stores, schools, and hospitals. Come January 2008, cafes and restaurants must also comply with bans. For now, smoking in these areas is permitted in hermetically sealed rooms without any services.

Joey, my oldest child, is six years old and already quite a clever creator. He can make houses out of sticks and boats out of cardboard boxes. He can build an entire city with toy blocks and crafty cabins with the same Lincoln Logs his daddy used more than 30 years ago. Most recently, Joey has been sharpening his skills with Lego.

Today, while his daddy built him a Lego jet, Joey constructed his own masterpiece. He called it his Cancer Center.

I wasn't around to hear Joey dedicate his building to such an important cause. But I heard about it after the fact when Joey offered me a mini-tour of the structure. I learned that the center has a helicopter landing pad and offices with windows for the employees. I was shown an emergency vehicle with its own system for taking blood from patients, rendering it healthy, and then returning it to the body. And then just as I wanted more -- more details, more specifics, more history on just why he built this cancer center -- Joey's attention moved elsewhere. And so I know nothing more about the cancer center sitting in the playroom of my house.

Cancer is no strange topic for Joey who has been along on my own cancer ride for the past two years -- so perhaps I am the inspiration for his architectural creation. But I suspect the real driving force behind Joey's latest project is the vacant land we passed yesterday. This land is the future site of a new cancer center in our city, and Joey probably heard me talking about the ground breaking ceremony that just took place. Regardless, cancer was on his mind this morning. And while the topic may be far from his mind now -- and I'm sure the building will be demolished by the day's end -- I am touched that for mere moments, Joey was invested in a noble cancer endeavor.

In 11 years, ABC management is claiming that nine women from the Brisbane Toowong studios have been diagnosed with breast cancer. A Brisbane law firm is claiming as many as 12 women have been diagnosed with breast cancer. Either way, the staff and journalists have come to the conclusion they are working in the midst of a cancer cluster and the Media Entertainment and Arts Alliance union who represents them wants the offices relocated by the end of next week. In the meantime, the union does not believe any of the staff should be forced to return to work until the offices are relocated.

But ABC management is saying independent surveys have shown there is no link between the incidence of breast cancer and the workplace. When Queensland Health investigated, they called the high incidence of breast cancer cases excessive, but stopped short of calling the circumstances the result of a cancer cluster. Let's see. The mother of two in her early 30s -- who was forced to undergo a mastectomy last week -- was the 12th woman to be diagnosed with breast cancer -- and the seventh to work in the same room at the Toowong studios.

What is the distinction made by Queensland Health, between cancer excess and cancer cluster? Would you continue working in an environment where a high number of cancer cases seem to be keep occurring?
