D. A Kiss Isn't Always Just A Kiss

Narrator: A KISS isn't always just a kiss. This is Science Today. Environmental health expert Katherine Hammond of the University of California, Berkeley did a study showing that workplaces that allow smoking expose non-smokers to dangerously high levels of passive smoke. Now, closer to home, she's working on a program called KISS -- Keeping Infants Safe from Smoke. That is, their parents' cigarette smoke.

Hammond: Young children are very much at risk from passive smoking. It's been clearly demonstrated that they have higher rates of bronchitis, pneumonia, various lung diseases. And attacks of asthma are much more serious among children whose parents smoke, and they have them more frequently.

Narrator: Hammond is looking at ways to motivate parents to reduce their kids' exposure to passive smoke.

Hammond: Obviously the best would be if the parents didn't smoke at all, but we understand that smoking is a very very addictive habit, extremely difficult to break, and I think we all of us have to be tolerant of smokers. But at the same time non-smokers should not be exposed to this toxic material.
