A. How an Anti-smoking Workplace Affects Smokers

Narrator: Narrator: This is Science Today. Smokers working in a non-smoking environment are more likely to quit than those not in a smoke-free workplace. Dr. Joel Moskowitz of the University of California, Berkeley's School of Public Health, was co-author of a new study which looked into whether California smoking laws had any effect on workers' ability to quit.

Moskowitz: We were able to merge the smoking data with the smoking law data and look at the relationships between smoking laws and quitting smoking, controlling for a whole host of other factors related to the type of smoker and the type of workplace. Then, seek above and beyond all those factors, whether a person worked in a community with no law versus one that worked in a community with a weak or strong law - whether it made any difference in terms of their ability to quit smoking.

Narrator: They found that smokers in anti-smoking areas were thirty-eight percent more likely to quit over a six month period than those in environments without strong anti-smoking laws.

Moskowitz: The more you can structure environments for smokers such that there's no smoke around them, the easier it is for them to quit smoking.
