You should think about protecting your pets from secondhand smoke. According to researchers at Oklahoma State University, secondhand smoke has been determined cancer-causing for household pets, such as dogs, cats, and birds

"There have been a number of scientific papers recently that have reported the significant health threat secondhand smoke poses to pets," says Dr. Carolynn MacAllister, an Oklahoma State University Cooperative Extension Service veterinarian. "Secondhand smoke has been associated with oral cancer and lymphoma in cats, lung and nasal cancer in dogs, as well as lung cancer in birds."

The news about smoking just keeps getting worse and worse. When we will get the hint?

Vincent Rennich, veteran casino worker and non-smoker, is suing the Atlantic City Tropicana Casino and Resort because he claims a quarter-century of inhaling secondhand smoke gave him lung cancer. And if that's not enough to make this man upset, getting fired seals the deal.

"They threw me under the bus," Rennich said yesterday, the day after a supervisor told him he was terminated from his job. "How can you fire a guy with lung cancer who's suing you? Maybe they don't realize the ramifications. Or maybe they're heartless. Or maybe all of the above."

Tropicana officials say that Rennich was not singled out in any way, that he was just one of many let go due to a restructuring of the company. Since last January, more than 200 people have been laid off.

Rennich, 49 and a table games supervisor, has been a vocal advocate of a total smoking ban in Altantic City's 11 casinos. He has been speaking out on behalf of everyone working on the casino floors, and for himself personally.

Rennich had a third of his right lung removed in September 2005 and sees a doctor every three months to ensure his cancer does not reappear. Now that he's been fired, his health insurance will lapse in 30 days, leaving him with a monthly payment of $800 in medical bills.

Atlantic City was slated to ban all casino smoking this past January. But fierce opposition from the casino industry, predicting an estimated revenue loss of 20 percent and job losses of more than 3,400, led to a compromise. And now, effective April 15, smoking will be restricted to no more than 25 percent of the gambling floor.

Rennich is not happy about this -- or his cancer or his termination. And while he is not sure what his next step will be, he says he is definitely not backing down from his anti-smoking platform.

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.

This past summer, a man in the business of helping smokers quit, was diagnosed with inoperable lung cancer. Just months later, anti-smoking guru Allen Carr lost his battle with cancer. On November 29th, Carr died at his home in Malaga, Spain.

A heavy smoker for 33 years before quitting 23 years ago, Carr claimed to have found an easy way to quit smoking. From that discovery, he founded The Easy Way to Stop Smoking Program, which would eventually grow into 70 clinics in 30 countries. In addition, his company publishes how-to quit smoking books, CDs, tapes and DVDs.

Using cognitive therapy, Carr told smokers interested in quitting that they could do it without willpower, without suffering withdrawal and without gaining weight. The celebrity endorsements for his program include Sir Anthony Hopkins, Sean Bean, Marie Helvin, Johnny Cash, George Harrison, Lisa Stansfield, Sir Richard Branson, Britney Spears, Susannah York, Bruce Oldfield, Stefano Gabbana and Julie Christie.

Carr is credited with helping over 25 million people to quit smoking.

An Easy Way to Stop Smoking Program clinic spokesperson was quoted as saying, "Allen spent many years in smoke-filled rooms after he quit, while treating smokers for addiction. He is certain that had he not quit, he would have died 20 years ago." Near the time of his death, Carr wrote a letter to Tony Blair urging his government and NHS to accept the easy method program. Carr was 72.

Is smoking or not smoking a choice for everyone? While some cities are banning smoking in public places and some conscious efforts around the US are setting standards to stop smoking in the work place -- and restaurants are following a pattern to either end smoking in their establishments or to designate an area just for smokers -- it is still up to a lot of individuals to make choices where they will go in public to avoid cigarette smoke.

Twenty percent of lung cancers in women are from non-smokers who were exposed to second hand smoke. This statistic seems to be on the rise. But it is not just lung cancers that are affected by second hand smoke. Other types of cancers have been related to smoking or second hand smoke.

As adults we all have to make choices daily whether to go hang out with friends in a bar or night club that allows smoking, or to visit with a friend or family member in their house and they are a smoker. But what about the children? What choices do they have to stay away from parents, guardians, or baby sitters or other family members that are smokers? Children face a higher risk than adults of the negative effects of second hand smoke. Not only is a child's body still developing physically, but their breathing rate is faster than that of adults. Children breathing second hand smoke have many more illnesses like ear infections, bronchitis, allergies, and stunted growth.

So if you are trying to find some way to help you quit smoking, think about the health of your children or the children you are around. If you need another reason, remember that kids of a parent that smokes are more likely to start smoking themselves when they get older.  Do you want your kids to have an increased risk of lung cancer or heart attacks because they learned to smoke from you?

If you just can't quit, then make a conscious effort to smoke outside of the home and do not smoke in the car.  Also consider using smokeless ashtrays.  Cut down on the amount of exposure to second hand cigarette smoke for your child who does not have the choice.
