A recent study conducted by the Harvard School of Public Health found that children living in smoke-free homes had 39% lower levels of the nicotine byproduct cotinine in their systems compared with children living in homes that were not smoke-free. This suggests that clean indoor air laws are an effective method of lowering children's exposure to secondhand smoke.
