Flavoring Liquids Used in E-cigarettes could Damage Lungs: Study

Flavoring liquids used in e-cigarettes could damage lungs, a US study claims. Findings of a new study have shown that e-cigarette liquids sweetened with flavorings like vanilla and cinnamon can lead to liver disease even if these chemicals do not contain nicotine.

The study was published in Frontiers in Physiology on Jan. 11, by a team of researchers from the University of Rochester Medical Center in upstate New York.

The team investigated the effect of these flavoring compounds on monocytes, a type of white blood cell by exposing to the flavoring chemicals that are used in popular e-cigarette liquids. The researchers found that even without nicotine, the flavoring chemicals caused inflammation and tissue damage to the cells. Many of these compounds also caused the lung cells to die.

They also found that this type of cell damage can lead to a range of lung problems which include fibrosis, asthma, and chronic obstructive pulmonary disorder, according to senior study author Irfan Rahman, an environmental health researcher at the University of Rochester Medical Center in upstate New York.

The researchers stated, “Our data suggest that the flavorings used in e-juices can trigger an inflammatory response in monocytes, mediated by ROS production, providing insights into potential pulmonary toxicity and tissue damage in e-cigarette users.”

However, flavoring chemicals are considered safe to ingest, but these new study findings suggest they are not safe for inhalation. Flavoring liquids used in e-cigarettes could damage lungs.

Rahman said that the research results show that e-liquid flavors should be regulated and they advise regulatory agencies to act to protect public health.
