Narrator: This is Science Today. A University of California, San Francisco study has found that teen smokers are more likely to quit due to their belief that secondhand smoke will harm others. These findings may add another element to anti-smoking campaigns directed at teens. For example, researcher Joel Moskowitz of the University of California, Berkeley, has found that adults in a smoke-free workplace were more likely to quit smoking due to what he calls the 'nuisance' factor.
Moskowitz: If people smoke, non-smokers are quite aware of it and it bothers them and often times they speak up, particularly if the press does its job in sort of featuring the aspects of smoking that are really dangerous and deadly to the non-smoker as well as the smoker.
Narrator: Moskowitz found that stricter anti-smoking laws, which result in a non-smoking environment, helped adults break the habit.
Moskowitz: Because they're simply smoking fewer cigarettes and perhaps because one of the predictors of the ability to quit is how addicted you are to nicotine, because they're smoking fewer cigarettes, they may ultimately find it much easier to quit.
