Scientists at the University of California, Riverside have found that second hand tobacco smoke can result in nonalcoholic fatty liver disease (NAFLD). This disease involves people who drink little or no alcohol yet still have fat deposits in their liver. NAFLD can eventually lead to liver dysfunction, which is fatal.

"Our study provides compelling experimental evidence in support of tobacco smoke exposure playing a major role in NAFLD development," said Manuela Martins-Green, who led the study.

This study shows that not only does second hand smoke cause cardiovascular disease and pulmonary disease, but is now linked to liver disease as well. The diseases that have already been established as being associated with second hand smoke are cancer, heart disease, bronchitis, asthma, and pneumonia.

The people who are most commonly affected by second hand smoke are children and partners who live in a household with someone that smokes. The new findings are just another reason why it's important to quit smoking not only for yourself for your loves ones around you.
